摘要
Abstract
In this thesis,Al0.25Li6.25La3Zr2O12(LLZO)-coated LiCoO2(LCO)materials were prepared by solid-phase sintering to improve interface stability and reduce interface impedance.The experimental results show that the electrochemical performance is significantly improved.When charged and discharged for 50 cycles in the voltage range of 3.0-4.62 V,the specific capacity retention rate of the coated material is 70%,which is higher than 65%of the uncoated material.In addition,the charge transfer resistance of the coated material was reduced from 22.5 Ω to 15.0 Ω,rate performance was improved.The effect of solid electrolyte LLZO coated lithium cobalt on electrical properties was studied in this work,and has great reference significance for the design of fast charge lithium cobalt oxide battery material.关键词
