In response to safety issues with liquid electrolytes, solid-state electrolytes have emerged as an attractive alternative for lithium-ion batteries. Hybrid solid electrolytes are a promising strategy for all-solid-state lithium-ion batteries (ASSLiB) due to their outstanding electrochemical and mechanical properties. In this study, we propose a hybrid solid electrolyte (HSE) fabricated by embedding LATP nanoparticles into the semi-interpenetrating network of polyacrylonitrile/poly(ethylene glycol) dimethacrylate. The HSE exhibits desirable flexibility, sufficient mechanical strength of 1.76 MPa, excellent Li+ conductivity of 1.07 x 10−3 S cm−1, and an outstanding Li+ transference number of 0.64 at room temperature in a wide electrochemical window up to 4.8 V vs. Li+/Li, maintaining the long-term stability with Li metal over 1000 cycles. Based on those excellent properties, HSE can show potential for ASSLiB.
