ELECTRODE MATERIAL FOR LITHIUM ION BATTERIES AND LITHIUM ION BATTERIES THEREOF

摘要

Electrode materials for lithium ion battery and lithium batteries thereof are disclosed. The electrode material for lithium ion battery comprises an electrode active material, an adhesive and a hydrogen storage alloy. The hydrogen storage alloy is selected one or more from the group consisting of AB5 type Nickel based hydrogen storage alloys, AB2 type Laves phase hydrogen storage alloys, A2B type Magnesium based hydrogen storage alloys, and V-based solid solution type hydrogen storage alloys. The lithium battery containing the same is also provided herein. The invention can relieve the air-expanding of lithium ion battery during formation and cycle, especially for battery using lithium titanate as its electrode active material.
