Lithium batteries with high energy and power density and process for their production.

摘要

High energy and high power lithium storage batteries, comprising and anode of lithium or lithium alloy, a non-aqueous electrolytic solution containing a lithium salt in one or more organic solvents or a solid electrolyte consisting of a lithium salt/polymeric material complex, and a cathode based on a lithium-vanadium oxide of nominal stoichiometric formula LiV3O8, which is obtained in the amorphous form by means of a new process of synthesis in aqueous solution. The choice of the amorphous form for the cathode material provides better performance with respect to the corresponding material in the crystalline form.
