Abstract Solid‐state batteries (SSBs) have attracted much attention for high‐energy‐density and high‐safety energy storage devices. Solid polymer electrolytes (SPEs) emerged as a critical component in the advancement of SSBs, owing to compelling advantages strong molecular structure‐designability, low cost, easy manufacturing, no liquid leakage. However, linear SPEs usually room‐temperature ionic conductivity due crystallization, melting at high temperature. Thus, crosslinked been proposed that chemical bonding between internal molecule chains can maintain solid state expand operational temperature, disrupt regularity segment, diminish crystalline degree, leading an enhancement conductivity. Furthermore, integration functional groups within SPE network significantly augment electrochemical performance SPEs. Herein, according structure, are categorized into four types: simple network, AB polymers (ABCP), semi‐interpenetrating (semi‐IPN), interpenetrating (IPN), then structure features disadvantages commonly used these types reviewed. In addition, with self‐healing, flame‐retardant, degradable, recyclability introduced. Finally, challenges prospects summarized, hoping provide guidance design future.
