Li/MnO_2电池用LiTFSI系电解液的研究

Abstract

为改善lI/MnO2电池的低温放电性能,制备了一系列新型lITfSI系电解液,并且溶剂中加入适量乙酸甲酯.研究结果表明,电解液lITfSI(1 MOl/l)/PC∶dME∶EC∶MA是一种较好的体系.

To improve the discharge performance of Li/MnO2 batteries at low temperatures,a series of new LiTFSI-based electrolytes were prepared.The methyl acetate was added into the mixed solvent.The experiments indicate that the LiTFSI(1 mol/L)PC∶DME∶EC∶MA(1∶1∶1∶3) is a good electrolyte.
