Abstract:
Lithium titanate, Li 4 Ti 5 O 12 , particles containing surface hydroxyl groups are susceptible to unwanted gas generation (such as hydrogen) in the presence of water contamination when the particles are used as active anode electrode material in lithium-ion cells operating with an anhydrous liquid electrolyte. In accordance with this disclosure, the hydroxyl groups on the surfaces of the particles are reacted with one of a group of selected agents containing organic alkoxy groups to form hydrophobic moieties on the surfaces of the particles which effectively block water molecules from the surfaces of lithium titanate particles in the anode of the cell.

Claim (Index 14):
The method of  claim 13  wherein the aliphatic alkanol is applied as a liquid to contact the surfaces of the lithium titanate particles to replace the hydroxyl groups with alkoxy groups, and excess liquid alcohol and by-product water are then removed from the alkoxy-coated lithium titanate particles.
