Development and Electrochemical Performance Analysis of Arm Solid-state Lithium Battery Electrolyte Based on Synthetic Chemistry
This paper presents a novel chemical engineering synthesis method for developing an acrylic acid ester random copolymer(ARM)as a new type of solid-state lithium battery electrolyte.By adding inorganic fillers(such as A2O3 and SiO2)and optimizing the preparation process of the electrolyte,the ionic conductivity and electrochemical performance of the electrolyte were successfully improved.Experimental results show that the ARM-based electrolyte has an ionic conductivity of 3.2×10-4 S/cm at room temperature,with a lower activation energy and good lithium ion transference number.This electrolyte exhibits excellent cycle stability and rate performance in NCM811|Li full cells,demonstrating its potential for application in high-safety,high-energy-density solid-state lithium batteries.
