“…revealed that during the charging-discharging processes after in situ polymerization, the unreacted residual monomers in GPEs tend to decompose or deposit on the surface of the electrodes, which significantly increases the electrode//electrolyte interfacial resistance and results in a deterioration of cycle performance (especially at low temperature or high rate). 55 Approaches such as limiting the addition of active monomers, applying initiators with higher initiation efficiency and appropriately increasing the amount of initiators can reduce the content of residual monomers in the GPEs and therefore lead to an enhanced electrochemical performance of the polymer batteries. Furthermore, the highly active initiators and monomers deteriorate during the storage at room temperature, which decreases the uniformity of the as-prepared batteries.…”

Polymer electrolytes have attracted great interest for next-generation lithium (Li)-based batteries in terms of high energy density and safety. In this review, we summarize the ion-transport mechanisms, fundamental properties, and preparation techniques of various classes of polymer electrolytes, such as solvent-free polymer electrolytes (SPEs), gel polymer electrolytes (GPEs), and composite polymer electrolytes (CPEs). We also introduce the recent advances of non-aqueous Li-based battery systems, in which their performances can be intrinsically enhanced by polymer electrolytes. Those include high-voltage Liion batteries, flexible Li-ion batteries, Li-metal batteries, lithium-sulfur (Li-S) batteries, lithium-oxygen (Li-O 2 ) batteries, and smart Li-ion batteries. Especially, the advantages of polymer electrolytes beyond safety improvement are highlighted. Finally, the remaining challenges and future perspectives are outlined to provide strategies to develop novel polymer electrolytes for high-performance Li-based batteries.

“…The capacity retention ratios are 82.0% and 86.0% for the GPEtype battery with Technology 2 and battery using liquid electrolyte aer 50 cycles at 0.2 C. This slight difference in cycling performance can be explained as the side reaction of the unreacted monomer at the electrode surface, which forms a resistive lm and increases the interfacial resistance. 35 In contrast, the GPE type-battery with Technology 1 only exhibits a capacity retention ratio of 68.2% aer 50 cycles at 0.2 C, which is much lower than that for Technology 2. The charge and discharge curves of PVA-CN-based polymer LIBs at 0.2 C for some selected cycle numbers are shown in Fig.…”

“…Although chemical preparation approaches exhibit obvious advantages in terms of facile operation and superior electrochemical performance, the residual unreacted monomers may deposit or decompose on the electrode surfaces, increasing the electrode|electrolyte interfacial resistance and deteriorating the battery performance. [ 142 ] Therefore, optimizing the structure and dosage of monomers as well as raising the initiation efficiency of initiators to reduce the residual monomer amount is essential to enhance the performance of quasi‐solid alkali metal‐based 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.
