ZIF-based heterojunction filler enhancing Li-ion transport of composite solid-state electrolytes

Caption

The functional heterojunction TiO2@Zn/Co–ZIF is designed as a filler to fabricate a composite solid-state electrolyte (PVZT), which provides additional selective pathways for Li+ transport and effectively restricts anion migration through its confined pore size. The synergistic effect results in a high room-temperature ionic conductivity (8.8 × 10−4 S cm−1) and a lithium-ion transference number of 0.47, enabling a LiNi0.8Co0.1Mn0.1O2/Li full cell using PVZT stable cycle 1200 times at a 2C rate.
