Non-aqueous electrolytic solutions and non-aqueous electrolyte cells comprising the same

摘要: A non-aqueous electrolytic solutions which has self-distinguishing property, low reactivity to metal lithium and high withstand voltage is provided. The of the first invention comprise, as electrolyte, salt preferably LiPF 6 and, solvent, phosphoric acid esters following general formula [1]; ##STR1## wherein R 1 , 2 3 may be same or different, represent an alkyl group substituted by one more halogen atoms at least represents atoms. second solvents for trimethyl phosphate, linear carbonates represented [3]; ##STR2## (wherein methyl ethyl 7 a branched having carbon atoms) cyclic ; content trymetyl phosphate 10% volume electrolyte. solution suitable cell using material capable being doped dedoped with ions negative electrode active complexed oxide transition positive material.
