Abstract
A coated particle comprising a lithium titanate particle core encased by a polyimide coating, an electrode comprising a plurality of polyimide coated LTO particles an electro-active material, and a lithium ion battery comprising an anode, a cathode, a separator and electrolyte wherein the anode comprises a plurality of polyimide coated LTO particles. The polyimide coating effectively reduces the amount of gas formation typically encountered with use of lithium titanate in electrochemical cells.
