Lithium-Titanate as a Negative Electrode for Lithium-Ion Batteries

The safety issue of lithium-ion batteries is current important research area. In recent years, the trend is to use higher capacity batteries allowing user to store more energy, to extract it at a higher rate, and to extend the application to new fields such as electrical vehicles propulsion, and smart grid. The comprehension to the all safety aspects of these large energy storage batteries lies extensive demands for battery designers and manufacturers. The failure of lithium-ion battery is accompany by thermal runaway and the venting of toxic and highly flammable gases. That can occur due to exposure battery to excessive temperatures, external shorts, high discharge rate, faulty wiring, or due to internal shorts caused by cell defects. These effects depends on the materials from which the batter yis made of. This paper deals with negative electrode materials and electrolytes for lithium-ion batteries with enhanced higher fire safety.
