Abstract

Li-ion battery is currently considered to be the most proven technology for energy storage systems when it comes to the overall combination of energy, power, cyclability and cost. However, there are continuous expectations for cost reduction in large-scale applications, especially in electric vehicles and grids, alongside growing concerns over safety, availability of natural resources for lithium, and environmental remediation. Therefore, industry and academia have consequently shifted their focus towards ‘beyond Li-ion technologies’. In this respect, other non-Li-based alkali-ion/polyvalent-ion batteries, non-Li-based all solid-state batteries, fluoride-ion/ammonium-ion batteries, redox-flow batteries, sand batteries and hydrogen fuel cells etc. are becoming potential cost effective alternatives. While there has been notable swift advancement across various materials, chemistries, architectures, and applications in this field, a comprehensive overview encompassing high-energy ‘beyond Li-ion’ technologies, along with considerations of commercial viability, is currently lacking. Therefore, in this review article, a rationalized approach is adopted to identify notable ‘post-Li’ candidates. Their pros and cons are comprehensively presented by discussing the fundamental principles in terms of material characteristics, relevant chemistries, and architectural developments that make a good high-energy ‘beyond Li’ storage system. Furthermore, a concise summary outlining the primary challenges of each system is provided, alongside the potential strategies being implemented to mitigate these issues. Additionally, the extent to which these strategies have positively influenced the performance of these ‘post-Li’ technologies is discussed.

INID/INID WOU be SMahver an that OF LIDS due tO We 1oOWer (more negative) redox potential of Li (—3.05 V vs. SHE) against Ni (—2.71 V vs. SHE) and K (—2.93 V vs. SHE). However, this argument is too simplistic as the redox poten- tial depends on the type of solvent used (large deviation may occur between aqueous and non-aqueous electrolytes), and the properties of the applied electrodes. Even though the electrode potential depends on the half-cell configuration, to obtain a high full-cell voltage, suitable intercalation electrodes need to be selected for which the negative one releases very little energy during interaction with Na/K ions (redox potential close to Na/Nat or K/K* = 0 V) while the positive elec- trode releases a large amount of energy during interaction with Na/K ions (redox potential much positive than Na/Na* or K/K* = 0 V). This indicates that the cell voltage (E..1)) is dependent on the Gibbs energy change of the cell reaction (AG®), according to the following well-known relation [70] V.2.9. YWaAUIUUS IHIaleridalo. LU AUIOUe CUOMIOMEHL Plays PiVOtdalL role on the performance of NIBs/KIBs, and it accounts for 1/3rd of the total expense of the battery pack [79, 80]. Intensive R&D activities are going on around the globe to explore appro- priate cathode materials having distinct structures. Amongst three types of cathode materials (such as LTMO, polyanionic compound, and PBA), LTMOs are used extensively, as they can accommodate the higher ionic radii of Nat/K* (against Lit) within the interlayer spacings during intercalation, to withstand the volume expansion [72], leading to higher capa- city than the others. But the aforementioned volume expan- sion sometimes leads to poor stability of the cathode. However, polyanion-based and PBA cathodes show longer stability, and higher working voltage due to the inductive effect and strong covalent bonds to form stable framework [74]. Especially, the PBA systems show higher volumetric as well as gravimetric energy density against LTMOs and polyanion-based cathodes with increasing alkali-ion size [38]. This implies that, com- paratively, for KIBs, PBAs work best, while LTMOs perform- ance are relatively better for LIBs, whereas polyanionic cath- odes perform well in Na-systems. Obviously, this is a general notion, and with proper modulations, these electrodes can be optimized for best performance in NIB/KIB systems too. Few types of NIB/KIB cathodes are shown in table 4. Rest can be found in the following references [56, 66, 67, 71, 73, 75, 76, 80-90].

maintained without the negative and positive active materials coming into direct contact with each other. During charging, electrons released at the positive electrode (through oxidation of the electroactive species in that half-cell) are pushed round the external circuit to the negative electrode (where reduction of electroactive species in that half-cell takes place). The pro- cesses are reversed on discharge, and the cell voltage is con- stituted through the voltage difference between the negative and positive electrode reactions [289-291]. The electroactive materials are redox pairs, i.e. chemical compounds that can reversibly undergo reduction and oxidation, such as V/V (four different vacancy states of V, cf figure 8(h)), Fe/Cr, Zn/Br etc. On the other hand, most RFBs use carbon electrodes, which do not participate in the energy conversion reactions. Generally, in RFBs, glassy carbon, pristine graphite, non- activated graphite felt etc. are used, which exhibit expectedly low electric double layer capacitor (EDLC) behavior, due to the absence of defects and primary exposure of basal planes, and hence negligibly affect the overall electrochemical per- formance. However, chemical, and thermal activation of these electrodes to incorporate functional groups to improve redox activity sometimes increase the EDLC behavior due to the introduction of greater number of defects. But its influence is also marginal as these double layers do not provide relevant active sites for increase in the redox reactions to the same extent, and hence, does not affect the overall electrochemical performance significantly [292]. Also, these electrodes do not cause any side reactions (like undesirable byproducts, and gas formation) to deteriorate the battery performance [230, 293-300]. The generalized electrochemical process in RFBs can be summarized using A/A™~ as the negative, and B/B™ as the positive redox pairs {with E°(A/A~) < E°(B/B~)}, con- tained within the respective electrolytes (called anolyte and catholyte), where the reactions take place on the electrode- electrolyte interface as follows [295]: where, V°+/V** oxidation states are composed of the pair VO/VO"*, respectively. As described in figure 8(h), during charging, V*+ is oxidized to V**, losing one electron which is driven to the other half cell where it reacts with V**, reducing it to V+. State-of-charge (SoC) for the battery is defined as the percentage of charged species (V°+ and V*+) in respect to the discharged species (V*+ and V7+). Cations X+ (e.g. H*) pass through the membrane to maintain the charge neutrality. Opposite process occurs during discharge, creating a discharge potential [295]: RFBs are electrochemical storage systems that consists of two separate liquids (anolyte and catholyte in separate tanks) flowing (through pumps) on either side of an ion-selective/ion- exchange membrane within a flow cell (cf figure 8(h)), where the chemical energy contained within the system converts to electrical energy via ion exchange through the membrane, accompanied by current flow through an external circuit/load. Fundamentally, the flow cells on either side of the porous membrane act as half cells and the redox reactions during charge and discharge take place at the electrodes of the half cells. The ion-permeable membrane or separator ensures that the liquids of the half cells mix as little as possible and a charge balance between positive and negative half cells is

Table 5. Hydrogen production via different pathways. solar and wind power generation makes hydrogen production via renewables cheaper. All these lead to an increment in the production of green hydrogen, and projected to a market value of $108.64 billion by 2031. Also, the number of publications on the production of green hydrogen (via electrolysis and pho- toelectrochemical methods) has increased steadily over the last decade, as shown in figure 13(c), indicating its great potential for the development of a sustainable future [495-500]. Chemical method of hydrogen storage is a materials-based hydrogen storage system, where the hydrogen gas interacts with the storage media. This interaction can be weak van der Waals force or moderate Kubus interaction or strong ionic/covalent bond formation. Chemical method recently gained considerable attention due to the fact that hydrogen storage capacity of certain materials is considerably higher than that of compressed, cryo-compressed and/or liquified hydrogen storage methods. Typically, chemical method can be categorized into (1) solid-state storage, and (2) chem- ical storage (cf figure 14). The solid-state storage techno- logy involves on-board regenerable materials, which means the storage material can be re-charged by hydrogen on-board a vehicle, whereas in chemical storage, this hydrogen rechar- ging should be done off-board, in a centralized facility, due to unfavorable kinetics and/or thermodynamics of the gas- solid system. Apparently, on-board regeneration is conveni- ent, simple, and cost-effective than that of off-board regenera- tion, and hence, solid-state storage materials are preferred over chemical storage materials. The solid-state hydrogen storage materials (on-board regenerable) can further be divided into (i) reversible hydrides, and (ii) physisorption materials. The reversible hydrides are based on strong interactions between the hydrogen and the host, where the host can be a metal or bimetallic alloy, like MgH2, ZrMn2H,2 (AB>-type alloy), Mg 2NiHy (A2B-type alloy), FeTiH2 (AB-type alloy), LaNisHe (ABs-type alloy), etc. In this type of materials, the chem- ical bonds are having both covalent and ionic characters and the hydrogen atoms are located at the interstitial positions of the crystal lattice sites of the metal hydride. The major issues with this type of reversible hydrides are low gravi- metric capacity, high temperature synthesis, high operating temperature, high cost of rare-earth metals, among others. To overcome these shortcomings, some complex hydrides are investigated which are mainly doped versions of lighter metal

Also, the number of publications on the production of green hydrogen (via electrolysis and pho- toelectrochemical methods) has increased steadily over the last decade, as shown in figure 13(c), indicating its great potential for the development of a sustainable future [495-500]. Chemical method of hydrogen storage is a materials-based hydrogen storage system, where the hydrogen gas interacts with the storage media. This interaction can be weak van der Waals force or moderate Kubus interaction or strong ionic/covalent bond formation. Chemical method recently gained considerable attention due to the fact that hydrogen storage capacity of certain materials is considerably higher than that of compressed, cryo-compressed and/or liquified hydrogen storage methods. Typically, chemical method can be categorized into (1) solid-state storage, and (2) chem- ical storage (cf figure 14). The solid-state storage techno- logy involves on-board regenerable materials, which means the storage material can be re-charged by hydrogen on-board a vehicle, whereas in chemical storage, this hydrogen rechar- ging should be done off-board, in a centralized facility, due to unfavorable kinetics and/or thermodynamics of the gas- solid system. Apparently, on-board regeneration is conveni- ent, simple, and cost-effective than that of off-board regenera- tion, and hence, solid-state storage materials are preferred over chemical storage materials. The solid-state hydrogen storage materials (on-board regenerable) can further be divided into (i) reversible hydrides, and (ii) physisorption materials. The reversible hydrides are based on strong interactions between the hydrogen and the host, where the host can be a metal or bimetallic alloy, like MgH2, ZrMn2H,2 (AB>-type alloy), Mg 2NiHy (A2B-type alloy), FeTiH2 (AB-type alloy), LaNisHe (ABs-type alloy), etc. In this type of materials, the chem- ical bonds are having both covalent and ionic characters and the hydrogen atoms are located at the interstitial positions of the crystal lattice sites of the metal hydride. The major issues with this type of reversible hydrides are low gravi- metric capacity, high temperature synthesis, high operating temperature, high cost of rare-earth metals, among others. To overcome these shortcomings, some complex hydrides are investigated which are mainly doped versions of lighter metal

Theodore Azemtsop Manfo

Turkish Journal of Materials, 2023

Lithium-ion batteries (LIBs) have significantly impacted our lives and are now found in various devices such as cell phones, laptops, and electric vehicles. An appropriate electrolyte was produced in LIBs via a twisting route, which relates to the progress of electrode chemistry. Based on recent research and discoveries, LIB has emerged as the technology of choice for storing electrical energy for use in mobile products and electric vehicles. This is due to LIBs' desirable qualities, such as their lightweight, high-energy density, small size, little memory effect, extended lifespan, and low pollution. In this method, a metal oxide is the cathode, and porous carbon is the anode. The electrochemical interaction of lithium with anode materials can generate intercalation products that are the basis for innovative battery systems. At room temperature, structural retention makes this reaction quick and reversible. This concise overview examines the progress of LIB technology and the impact of the materials used in different technologies on cell performance. The section summarizes the evolution of LIB cells and Li + ion storage into various materials and intercalation chemistry.

The energy-storage frontier: Lithium-ion batteries and beyond
Elizabeth Kocs

MRS Bulletin, 2015

History of the lithium-ion battery The story of the lithium-ion (Li-ion) battery is a fascinating study in how science and technology transform expansive general ideas into specifi c technology outcomes, advanced by many scientifi c disciplines and players in diverse international settings. The fi nal product, what is now called the Li-ion battery (illustrated in Figure 1), continues to have a transformational impact on personal electronics, affecting communication, computation, entertainment, information, and the fundamental ways in which we interact with information and people. In recounting this story, we acknowledge the basic themes it illustrates: vision, challenges, course-changing discoveries, outcomes that miss intended targets yet have transformational impacts, and compelling opportunities left on the table. Several accounts of the history of Li-ion batteries have recently appeared. 1-9 This article presents a brief overview of the motivations, challenges, and unexpected solutions in Li-ion battery development, as well as the failures and triumphs that have marked their trajectory from conceptualization through commercialization to their dominant place in the market today. The concept: Li-metal anodes and intercalation cathodes It is easy to understand the appeal of Li as a battery material. As the most reducing element and the lightest metal in the periodic table, Li promises high operating voltage, low weight, and high energy-storage density. These appealing features of Li have been known and discussed for use in primary (nonrechargeable) and secondary (rechargeable) batteries since the 1950s, 10-12 and several primary batteries reacting Li with cathodes such as (CF) n , MnO 2 , aluminum, and iodine were proposed or developed in the 1960s. 13 Early work on Li rechargeable batteries used molten lithium and molten sulfur as electrodes, separated by a molten salt as the electrolyte, operating at ∼ 450°C. 13 A pathway for using lithium in room-temperature rechargeable batteries was established in the early 1970s, when Whittingham and others realized that electrochemical intercalation of guest molecules into layered hosts, previously viewed as a synthesis technique, could also be used to store and release energy in battery electrodes. 7 , 8 , 13-16 One of the triggers for this intellectual leap was the synthesis of more than

As a forefront energy storage technology, lithium-ion batteries (LIBs) have garnered immense attention across diverse applications, including electric vehicles, consumer electronics, and medical devices, owing to their exceptional energy density, minimal self-discharge rate, high open circuit voltage, and extended lifespan. However, despite their remarkable advancements and widespread commercialization, LIBs continue to face critical challenges, particularly the demand for even higher energy density, which inhibits their performance in high-power applications such as electric and hybrid electric vehicles. This review presents a comprehensive analysis of the fundamental limitations hindering LIBs from achieving superior energy density and long-term electrochemical stability. The discussion is systematically structured around four key components: cathode materials, anode materials, separators, and current collectors, with a particular emphasis on the challenges, emerging strategies, and future perspectives. By delving into recent breakthroughs in novel material architecture, electrode design optimizations, and the selection of advanced separators and current collectors, this work provides an in-depth examination of innovative approaches aimed at enhancing battery performance. Furthermore, this review explores pivotal factors such as interfacial stability, ion transport kinetics, and degradation mechanisms that significantly impact the longevity, safety, and efficiency of LIBs. By critically evaluating these aspects, it offers valuable insights into the trajectory of LIB development, helping to shape the next generation of high-performance energy storage solutions.

Emerging and Recycling of Li-Ion Batteries to Aid in Energy Storage, A Review
Shammya Afroze

Recycling

The global population has increased over time, therefore the need for sufficient energy has risen. However, many countries depend on nonrenewable resources for daily usage. Nonrenewable resources take years to produce and sources are limited for generations to come. Apart from that, storing and energy distribution from nonrenewable energy production has caused environmental degradation over the years. Hence, many researchers have been actively participating in the development of energy storage devices for renewable resources using batteries. For this purpose, the lithium-ion battery is one of the best known storage devices due to its properties such as high power and high energy density in comparison with other conventional batteries. In addition, for the fabrication of Li-ion batteries, there are different types of cell designs including cylindrical, prismatic, and pouch cells. The development of Li-ion battery technology, the different widely used cathode and anode materials, and ...

Promise and reality of post-lithium-ion batteries with high energy densities
Doron Aurbach

Nature Reviews Materials, 2016

Energy density is the main property of rechargeable batteries that has driven the entire technology forward in past decades. Lithium-ion batteries (LIBs) now surpass other, previously competitive battery types (for example, lead-acid and nickel metal hydride) but still require extensive further improvement to, in particular, extend the operation hours of mobile IT devices and the driving mileages of all-electric vehicles. In this Review, we present a critical overview of a wide range of post-LIB materials and systems that could have a pivotal role in meeting such demands. We divide battery systems into two categories: near-term and long-term technologies. To provide a realistic and balanced perspective, we describe the operating principles and remaining issues of each post-LIB technology, and also evaluate these materials under commercial cell configurations.
