Abstract
An electrolyte for a battery comprises LiBOB salt in gamma butyrolactone and a low viscosity solvent. The low viscosity solvent may comprise a nitrile, an ether, a linear carbonate, or a linear ester. This electrolyte is suitable for use in lithium ion batteries having graphite negative electrodes. Batteries using this electrolyte have high conductivity, low polarization, and high discharge capacity.
