Polymer‐Based Solid‐State Electrolytes for High‐Energy‐Density Lithium‐Ion Batteries – Review

Abstract Portable electronic devices and electric vehicles have become indispensable in daily life and caused an increasing demand for high‐performance lithium‐ion batteries (LIBs) with high‐energy‐density. This work compares the intrinsic characteristics and Li + conduction mechanisms of various electrolytes, aiming at emphasizing their suitability for high‐energy‐density LIBs. Among all electrolytes, polymer‐based solid‐state electrolytes (SSEs) are the most promising candidates, as they demonstrate the most comprehensive properties. The advantages and disadvantages of commonly used polymer matrix materials of SSEs are discussed, along with typical approaches to address their limitations. As significant…
