1.Comparison of the electrochemical properties LiBOB and LiPFs in electrolytes for LiMn2O4/Li cells 1.1 LiPF6 Spinel lithium manganese oxide (LiMn2Oa)is considered a promising cathode material for lithium secondary batteries,but its poor cyclic ability,especially at high temperatures(above 55 C),remains a problem.One of the factors is related to spinel dissolution-the electrolyte salt LiPF will decompose at elevated temperatures. HF is generated as a product of the decomposing reaction and will dissolve manganese. PDF文件使用"pdfFactory Pro”试用版本创建m,fineprint.com,cn1.
