“…[88][89][90] Additionally, aqueous electrolyte also has the features of environmental benignity (nonvolatility and nontoxicity) and capability of fast charging and, thus, high power density based on the potentially high ionic conductivity of aqueous electrolyte. [91][92][93] Except for the obvious advantages, the practical applications of aqueous electrolyte are limited by its theoretically narrow electrochemical window of 1.23 V ( Figure 5A), 94 resulting in a low voltage and insufficient energy density of practical batteries. The risk of oxygen evolution reaction (OER) occurs at the cathode part and hydrogen evolution reaction (HER) at the anode part, resulting in electrolyte consumption, side reactions, and severe capacity decay.…”

Lithium ion battery has achieved great success in portable electronics and even recently electronic vehicles since its commercialization in 1990s. However, lithium-ion batteries are confronted with several issues in terms of the sustainable development such as the high price of raw materials and electronic products, the emerging safety accidents, etc. The recent progresses are herein emphasized on lithium batteries for energy storage to clearly understand the sustainable energy chemistry and emerging energy materials. The Perspective presents novel lithium-ion batteries developed with the aims of enhancing the electrochemical performance and sustainability of energy storage systems. First, revolutionary material chemistries, including novel low-cobalt cathode, organic electrode, and aqueous electrolyte, are discussed. Then, the characteristics of safety performance are analyzed and strategies to enhance safety are subsequently evaluated. Battery recycling is considered as the key factor for a sustainable society and related technologies are present as well. Finally, conclusion and outlook are drawn to shed lights on the further development of sustainable lithium-ion batteries.

Rechargeable alkali metal (i.e., lithium, sodium, potassium)‐based batteries are considered as vital energy storage technologies in modern society. However, the traditional liquid electrolytes applied in alkali metal‐based batteries mainly consist of thermally unstable salts and highly flammable organic solvents, which trigger numerous accidents related to fire, explosion, and leakage of toxic chemicals. Therefore, exploring non‐flammable electrolytes is of paramount importance for achieving safe batteries. Although replacing traditional liquid electrolytes with all‐solid‐state electrolytes is the ultimate way to solve the above safety issues, developing non‐flammable liquid electrolytes can more directly fulfill the current needs considering the low ionic conductivities and inferior interfacial properties of existing all‐solid‐state electrolytes. Moreover, the electrolyte leakage concern can be further resolved by gelling non‐flammable liquid electrolytes to obtain quasi‐solid electrolytes. Herein, a comprehensive review of the latest progress in emerging non‐flammable liquid electrolytes, including non‐flammable organic liquid electrolytes, aqueous electrolytes, and deep eutectic solvent‐based electrolytes is provided, and systematically introduce their flame‐retardant mechanisms and electrochemical behaviors in alkali metal‐based batteries. Then, the gelation techniques for preparing quasi‐solid electrolytes are also summarized. Finally, the remaining challenges and future perspectives are presented. It is anticipated that this review will promote a safety improvement of alkali metal‐based batteries.

Aqueous electrolytes were once the rule for the battery industry. Until the advent of lithium ion batteries, a majority of commercially relevant batteries utilized water as the solvent for ion exchange. The development of the intercalation‐based lithium ion battery upended the industrial aqueous electrolyte paradigm: the high energy density of the lithium‐ion battery was revolutionary but required the use of organic electrolytes capable of passivating strongly redox active electrodes. With the safety of organic electrolytes becoming an issue in the early 1990s, a small community re‐examined aqueous electrolytes for lithium ion batteries. The first such audacious attempt was by Dahn et al., who conceptualized an aqueous lithium‐ion battery chemistry based on electrode materials suitable for the narrow electrochemical stability window of water, sacrificing energy density and cycle life for safety and low cost. The concept of an aqueous lithium‐ion battery was revived in the mid‐2010s with “highly concentrated” electrolytes, expanding the electrochemical stability window of water to regions comparable with nonaqueous electrolytes. Since then, significant efforts have been made around the world, aiming to understand the nature of the interfacial stability in those high‐concentration electrolytes as well as to further make the system viable for practical batteries. This review summarizes these efforts in this emerging frontier of new battery chemistries.
