Exploiting the synergy between organic polymer electrolytes and inorganic electrolytes via the development of composite electrolytes can suggest solutions to the current challenges of next‐generation solid‐state lithium‐metal batteries (SSLMBs). Depending upon a mass fraction of inorganic fillers and organic polymers, composite electrolytes are broadly classified into “ceramic‐in‐polymer” (CIP) and “polymer‐in‐ceramic” (PIC) categories, inheriting distinct structure and electrochemical properties. Since the stability and electrochemical characteristics of the inorganic phase are superior to those of the organic phase for lithium‐ion conduction, applying lithium‐enrich active filler in PIC seems more promising. The inorganic phase preserves the primary migratory channels in the PIC electrolyte, while the viscoelastic properties attempt to be introduced from the organic binder or host. The present work overviews the studies on state‐of‐the‐art PIC electrolytes, the fundamental mechanism of ionic conduction, preparation methods, and current progress in materials development for SSLMBs. In addition, the modification strategies for improving the electrode–electrolyte interface are also emphasized. Moreover, it further prospects the current challenges and effective strategies for the future development of PICs‐based CPEs to accelerate the practical application of SSLMBs. This review examines the progress and outlook of PIC‐based electrolytes for next‐generation lithium batteries.

Emerging portable energy systems with integrated sustainability and improved safety have garnered growing interest in wearable electronics. Herein, a self-charging zinc-ion battery is successfully developed by integrating a PVDF−ZnO piezoelectric separator immersed in a quasi-solid-state hydrogel electrolyte (prepared using a 3 m Zn(CF 3 SO 3 ) 2 ) solution that is sandwiched between a FeVO 4 cathode and a zinc anode. This battery effectively captures energy through controlled tapping, eliminating the need for external charging and enabling sustainable energy storage. This self-charging battery can be charged up to 181.23 mV under continuous tapping for 300 s. Upon the cease of tapping, there is a slight decline in the induced potential, which then stabilizes and maintains a consistent potential. Five self-charging batteries connected in series and tapped simultaneously for 300 s generate a potential of 290 mV, whereas five batteries connected in series and tapped one by one induce a potential of 345 mV. This is the first time that a piezoelectric self-charging zinc-ion battery is reported. This study unveils a transformative strategy for realizing nextgeneration wearable electronics with a self-charging zinc-ion battery design that prioritizes both sustainability and safety.
