Abstract

An electroactive material for use in an electrochemical cell, like a lithium-ion battery, is provided. The electroactive material comprises lithium titanate oxide (LTO) and has a surface coating with a thickness of less than or equal to about 30 nm that suppresses formation of gases within the electrochemical cell. Methods for making such materials and using such materials to suppress gas formation in electrochemical cells are likewise provided.
