“…By comparison, it can be observed that the 5% weight loss temperature of the PI polymer is about 100 °C higher than that of PI-COOH, and the gap is narrowed at 10% weight loss. Although the introduction of the −COOH group lowers the thermal decomposition temperature, the thermal properties of the PI-COOH still satisfy the requirement of thermal decomposition temperature . Appropriate electrolyte adsorption of the electrode can boost the diffusion of Li + to Si particles so as to achieve the high-rate capability and high-power capacity of lithium-ion battery .…”

Silicon has been considered as one of the most promising candidate anode material for Li-ion batteries due to its high theoretical specific capacity. Nevertheless, its low cycling performance due to the huge volume change during cycling hinders the commercial application of silicon anodes. Binders play a crucial role in Li-ion batteries and can effectively relieve the volumetric expansion stress of silicon anodes. Herein, we developed a polyimide binder with an introduced carboxyl group (PI-COOH). The introduced −COOH group can effectively bond with the oxide layer on the silicon surface through forming improved interface stability and then reducing the damage of the solid electrolyte interface film during cycling. Combined with the excellent intrinsic mechanical and thermodynamic properties of polyimide, the as-prepared PI-COOH binder significantly improved the cycling stability and rate performance of silicon anode.

High‐energy‐density lithium‐ion batteries (LIBs) with high safety have long been pursued for extending the cruise range of electric vehicles. Owing to the high gravimetric capacity, silicon is a promising alternative to the convention graphite anode for high‐energy LIBs. However, it suffers from intrinsic poor interfacial stability with liquid electrolytes, inevitably increasing the risk of thermal runaway and posing serious safety challenges. In this review, we will focus on mitigating thermal runaway of silicon anodes‐based LIBs from the perspective of electrolyte design. First, the thermal runaway mechanism of LIBs is briefly introduced, while the specific thermal failure reactions associated with silicon anodes and electrolytes are discussed in detail. We then summarize the safety countermeasures (e.g., thermally stable solid electrolyte interphase, nonflammable electrolytes, highly stable lithium salts, mitigating electrode crosstalk, and solid‐state electrolytes) enabled by customized electrolyte design to address these triggers of thermal runaway. Finally, the remaining unanswered questions regarding the thermal runaway mechanism are presented, and future directions to achieve intrinsically safe electrolytes for silicon‐based anodes are prospected. This review is expected to provide insightful knowledge for improving the safety of LIBs with silicon‐based anodes.
