摘要：

The metal-organic frameworks (Zeolitic imidazolate framework-67, ZIF-67) were in-situ grown on the cellulose skeleton surfaces which are rich in hydroxyl groups, and combined with PEO-based electrolytes to form composite solid electrolytes (CSEs). The assembled Li/CSEs/Li exhibit an ultra-long cycle life (>2000 h, 50 C-degrees; >2500 h, 30 C-degrees) and excellent lithium-ion transference efficiency (t(Li+) = 0.46) at 50 C-degrees. This work provides a new pathway for the development of high-safety and low-cost all-solid-state batteries.
