钛酸锂电池胀气成分的气相色谱分析OA北大核心CSCDCSTPCD
Analysis of components of lithium titanate battery by gas chromatography
介绍了使用气相色谱仪(GC)对钛酸锂(Li4Ti5O12)电池的胀气进行量化分析的方法.电解液成分不同的Li4Ti5O12软包电池在55℃循环多次后,产生不同程度的胀气.使用标准气体对气相色谱仪进行标定后,再对电池的胀气成分进行量化分析.发现使用碳酸乙烯酯(EC)作为电解液溶剂的主要成分时,CO2为生成气体的主要成分,其次是H2和CO.在EC基的电解液中加入硅烷作为添加剂时,CO2的含量超过90％,而且产气量也大大增加.当使用碳酸丙烯酯(PC)替…查看全部>>
A method of a quantitative analysis for the gases produced in the lithium titanate (Li4Ti5O12) batteries by gas chromatography (GC) was introduced.The soft-packing lithium titanate batteries produced gases after cycled at 55 ℃.The GC system was calibrated by standard gases.Then the gases produced during cycling were quantitative analyzed.It was found the gases mainly contained CO2,H2 and CO when Ethylene carbonate (EC) was used in the electrolyte.When silane…查看全部>>
