摘要/Abstract

摘要：

采用溶液浸渍法制备了聚乙烯醇(PVA)均匀包覆的石墨并研究了其微观形貌及电化学性能. 以LiNi_0.8Co_0.15Al_0.05O₂(NCA)为正极材料、 PVA包覆石墨为负极材料组装成软包电池和钢壳电池, 研究了PVA功能保护膜对全电池的电化学性能和存储寿命的影响. 结果表明, 存储过程中PVA功能保护膜可以有效抑制电解液和石墨内嵌锂反应的发生, 延长电池的存储寿命.

关键词: 聚乙烯醇, 表面包覆, 石墨负极, 储存寿命, 锂电池, 功能保护膜

Abstract:

Graphite anode uniformly coated with polyvinyl alcohol(PVA) was prepared by solution impregnation method. The morphology and electrochemical properties of graphite coated with PVA were stu-died. LiNi_0.8Co_0.15Al_0.05O₂(NCA) was used as cathode material and graphite coated with PVA was used as negative material to assemble soft-packed batteries. The effects of PVA coating on the electrical performance and storage life of full-scale batteries were studied. The results show that PVA coating can effectively inhibit the reaction between electrolyte and graphite-embedded lithium and prolong the storage life of the battery.

Key words: Polyvinyl alcohol, Surface coating, Graphite anode, Storage life, Lithium battery, Functional protective film
