摘要: 本文采用湿法包覆法成功制备了聚(3,4-亚乙基二氧噻吩):聚(苯乙烯磺酸盐) (PEDOT:PSS)包覆的LiNi0.8Co0.15Al0.05O2正极材料，研究了包覆改性前后材料的微观结构及电化学性能。LiNi0.8Co0.15Al0.05O2颗粒表面的聚合物PEDOT:PSS包覆层厚度大约为14 nm，PEDOT:PSS包覆的LiNi0.8Co0.15Al0.05O2具有良好的电化学性能，在0.1 C倍率下首次放电比容量193.8 mAh/g，1 C循环100次后容量保持率为90.3%。PEDOT:PSS包覆层具有高电导率，可以提高材料的导电性，因此PEDOT:PSS包覆的LiNi0.8Co0.15Al0.05O2具有高放电比容量、好的循环稳定性和良好的倍率性能。
Abstract: The poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) coated LiNi0.8Co0.15Al0.05O2 cathode material was successfully prepared by wet coating method, and their microstructure and electrochemical properties were studied. The conductive polymer films on the surface of the LiNi0.8Co0.15Al0.05O2 particles are about 14 nm thick, and the PEDOT:PSS-coated LiNi0.8Co0.15Al0.05O2 has good electrochemical performance. The first discharge specific capacity was 193.8 mAh/g at 0.1 C, and the capacity retention rate was 90.3% at 1C after 100 cycles. The PEDOT:PSS cladding layer has high electrical conductivity and can improve the electrical conductivity of the material. Therefore, the PEDOT:PSS-coated LiNi0.8Co0.15Al0.05O2 has high discharge specific capacity, good cycle stability, and good rate performance.
