METHOD FOR PRODUCING POROUS LITHIUM TITANATE, POROUS LITHIUM TITANATE AND LITHIUM BATTERY USING SAME

摘要

Disclosed are: a method for producing a porous lithium titanate, which exhibits excellent impregnatability of a nonaqueous electrolyte and is capable of improving charge/discharge cycle characteristics when used as an electrode active material for a lithium battery; a porous lithium titanate; and a lithium battery using the porous lithium titanate. Specifically, a ground mixture is obtained by mechanochemically grinding and mixing a starting material that contains a titanium source and a lithium source. The ground mixture is fired.
