Abstract
The viscosity of certain non-aqueous electrolytes comprising a first lithium salt which can gel on the addition of P.sub.2 O.sub.5 can be reduced substantially by incorporating therein a small amount of a suitable viscosity reducing salt. In particular, the viscosity of a LiPF.sub.6 salt based electrolyte can be reduced by orders of magnitude by incorporating a small amount of LiBF.sub.4 therein. Such electrolytes are suitable for use in lithium ion batteries.
