“…[46] Therefore, using nontoxic proteins as major components to directly prepare electrolytes for rechargeable batteries has been intensively reported in different battery systems recently (Table 1). [47][48][49][50][51][52][53][54] Moreover, as a representative of biological macromolecules, the unique self-assembly properties of proteins at the molecular level show immense potential for designing aqueous electrolytes. The application of proteins to prepare electrolytes can be traced back to 2018.…”

In pursuit of reducing environmental impact during battery manufacture, the utilization of nontoxic and renewable materials is essential for building a sustainable future. As one of the most intensively investigated biomaterials, proteins have recently been applied in various high‐performance rechargeable batteries. In this review, the opportunities and challenges of using protein‐based materials for high‐performance energy storage devices are discussed. Recent developments of directly using proteins as active components (e.g., electrolytes, separators, catalysts or binders) in rechargeable batteries are summarized. The advantages and disadvantages of using proteins are compared with the traditional counterparts, and the working mechanisms when using proteins to improve the electrochemical performances of rechargeable batteries are elucidated. Finally, the future development of applying biomaterials to build better batteries is predicted.

“…Lithium-ion batteries (LIBs) are becoming increasingly important in the field of electric vehicles. − Conventional lithium-ion batteries have a safety hazard due to liquid electrolyte leakage and thermal runaway from side reactions and exothermic reactions. Solid-state LIBs with nonflammable solid-state electrolytes can overcome safety and reliability issues. − However, the low ionic conductivity of solid-state electrolytes has hindered the cycling performances of batteries at room temperature. − Since 1973, poly(ethylene oxide) (PEO, polyether-based substance) had ushered in an era of polymers as solid-state electrolytes because of its good compatibility with the cathode, good stability, low price, and excellent machinability . However, its inherent ionic conductivity (σ) was lower than that of liquid electrolytes. − Subsequently, researchers also explored other solid-state polymer electrolytes, including carbonyl-coordinating polymers, polyamines, polyalcohols, and polynitriles.…”

Solid-state lithium batteries using solid polymer electrolytes can improve the safety and energy density of batteries. Smoother lithium-ion channels are necessary for solid polymer electrolytes with high ionic conductivity. The porosity and channel structure of the polymer film affect the transfer of lithium ions. However, their controllable synthesis remains a big challenge. Here, we developed a simple synthesis approach toward wrinkled microporous polymer electrolytes by combining the amphoteric (water solubility and organic solubility) polymer in three polymer blends. The homogeneous blend solution spontaneously wrinkled to vertical fold channels as the solvent evaporated. Two minor polymers, poly(vinyl pyrrolidone) (PVP) and polyetherimide (PEI), formed close stacks, and Janus PVP was dispersed in the poly(vinylidene fluoride) (PVDF) matrix. The interfacial tensions between the three polymers were different, so stress was produced when they solidified. The solvent was evaporated to the top layer of the polymers when the temperature increased. The bottom layer wrinkled owing to the stress during solidification. The evaporation of the solvent generated micropores to form the lithium-ion channel. They helped Li + transference and created a wrinkled microporous PVDF-based polymer electrolyte, which achieved an ionic conductivity of 5.1 × 10 −4 S cm −1 and a lithium-ion transference number of 0.51 at room temperature. Meanwhile, the good flame retardancy and tensile strength of the polymer electrolyte film can improve the safety of the battery. At 0.5C and room temperature, the batteries with a LiFePO 4 cathode and the wrinkled microporous LiTFSI/PEI/PVP/PVDF electrolyte reached a high discharge specific capacity of 122.1 mAh g −1 at the 100th cycle with a Coulombic efficiency of above 99%. The results of tensile and self-extinguishing tests show that the polymer electrolyte film has good safety application prospects.

Two-dimensional (2D) silicate materials have become one of the promising candidates for constructing composite polymer electrolytes due to their advantages of low cost, high stability, good mechanical property, high ionic conductivity and potential to inhibit the growth of lithium dendrites. However, the application of 2D silicate materials in composite polymer electrolytes (CPEs) is still at the infancy stage and facing a lot of challenges. In this minireview, we summarize the structures and properties of 2D silicate materials that have been applied in CPEs, the processing methods of composite electrolytes based on 2D silicates, and the recent process of 2D silicate materials in CPEs. We hope this review could present a general overview of the 2D silicates for CPEs and promote the further study for potential applications.
