Abstract

Electrolyte for use in lithium batteries, comprising lithium hexafluorophosphate or lithium bis(oxalato)borate dissolved in a solvent comprising ethylene carbonate and propylene carbonate, dimethyl carbonate, diethyl carbonate, ethyl methyl carbonate, butylene carbonate, ethyl acetate, methyl acetate, ethyl propionate and/or methyl propionate, includes up to 3 wt.% 2-methylfuran dissolved in the electrolyte. An independent claim is also included for an electrochemical cell comprising a cathode, an anode, a separator and an electrolyte as above, where the electrochemically active component of the anode comprises graphite and optionally carbon black.
