Negative electrode for a rechargeable lithium battery comprising a solid solution of titanium dioxide and tin dioxide

摘要

Solid solution of titanium dioxide and tin dioxide is utilized as the anode active substance in the negative electrode of a rechargeable lithium battery. The lithium battery comprised of a negative electrode containing particles of titanium dioxide-tin dioxide solid solution, a non-aqueous lithium ion bearing electrolyte and a positive electrode, usually made of a lithium containing chalcogenide compound provides stable voltage, has high reversible anode capacity and high energy density.
