Abstract

Gel Polymer Electrolytes (GPEs) can reduce the explosion risk of Lithium-Ion Batteries (LIBs) caused by liquid electrolytes leakage and thermal runaway, which has attracted extensive attention in recent years. Compared to all solid-state electrolytes, GPEs have the characteristics of easy processability and good interfacial compatibility. However, the poor mechanical performance and thermal stability of GPEs cannot meet the current requirements of LIBs. Metal Organic Frameworks (MOFs) have been found to be used as fillers for GPEs to improve the ionic conductivity and mechanical properties of solid-state electrolytes. Here, A novel bimetallic organic frameworks material containing Mn and Ni ions (NiMn-MOF) has been synthesized to improve the ion conductivity and thermal stability of the GPE. The LiNi_0.33Co_0.33Mn_0.33O₂(NCM-111)/Li half-cell prepared with NiMn-MOF GPE has a specific capacity of 144.4 mAh g^-1 at a rate of 0.1C and exhibits good rate performance.
