摘要

研究了应用于微型全固态薄膜锂离子电池的正极材料钴酸锂LiCoO

薄膜材料

采用磁控溅射法来制备

对其进行400℃退火处理后

进行XRD分析和SEM分析

表明在低气压条件下制备的薄膜呈非晶态

经过退火后

形成了排列致密的晶体结构

薄膜沿（003）晶面平行于基底择优生长;循环伏安测试和恒电流充放电测试表明

未经过退火处理的LiCoO

薄膜不具有锂离子嵌入/脱出的可逆性

而经过退火处理的LiCoO

薄膜从第二圈开始具有较好的可逆性。制备的LiCoO

薄膜结晶状态优良、质地紧密、与衬底薄膜紧密接触、循环性能和循环充放电性能良好

可以用于微型全固态薄膜锂离子电池。

Abstract

As positive electrode material

LiCoO

thin films used for all-solid-state thin film lithium ion microbattery are studied. The phase of LiCoO

thin films are amorphous

it is fabricated by magnetron sputtering in low gas pressure and it changes to crystalline and array closely after annealed at 400 ℃. The electrochemical properties of LiCoO

thin-films are then investigated. The cyclic voltammetry and constant current charge-discharge tests indicate that the LiCoO

thin films without annealed have no oxidation / reduction peaks

which indicates that they do not have lithium-ion insertion / extrusion of reversibility

whil

e the LiCoO

thin films after annealed have a good reversibility from the second lap. The prepared LiCoO

thin films closely adhere to the substrate with good crystalline state

close texture and good cycling performance

can be used for all-solid-states thin film lithium-ion microbatteries.
