摘要
文章采用一种化学工程合成方法开发了丙烯酸酯无规共聚物(ARM)新型化工固态锂电池电解质。通过添加无机填料(如A_(2)O_(3)、SiO_(2))并优化电解质的制备工艺,成功提高了电解质的离子电导率和电化学性能。实验结果显示,ARM基电解质在室温下的离子电导率达3.2×10^(-4)S/cm,且具有较低的活化能和良好的锂离子迁移数。该电解质在NCM811|Li全电池中表现出优异的循环稳定性和倍率性能,展现出在高安全性、高能量密度固态锂电池中的应用潜力。
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 SiO_(2))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.
