Title: Surface stabilized electrodes for lithium batteries

Patent ·
OSTI ID:1346344
; ;

A stabilized electrode comprising a metal oxide or lithium-metal-oxide electrode material is formed by contacting a surface of the electrode material, prior to cell assembly, with an aqueous or a non-aqueous acid solution having a pH greater than 4 but less than 7 and containing a stabilizing salt, to etch the surface of the electrode material and introduce stabilizing anions and cations from the salt into said surface. The structure of the bulk of the electrode material remains unchanged during the acid treatment. The stabilizing salt comprises fluoride and at least one cationic material selected from the group consisting of ammonium, phosphorus, titanium, silicon, zirconium, aluminum, and boron.
