摘要
为满足电动汽车等大功率装置的电池需求,研制高能量密度和高功率的电池材料是锂离子电池的重要研究方向之一。钛酸锂比其他负极材料具有更高的安全性和更好的循环性能,是一种较为理想的动力型锂离子电池负极材料,但该材料存在电子电导率较低、大倍率性能不够理想的问题。综述了目前国内外对Li4Ti5O12材料的研究进展,并对其发展方向做出展望。
In order to meet the needs of high power electric devices such as electric vehicle, battery materials with high energy density and high power are becoming necessary. Lithium titanate is a kind of ideal material for lithium anode, for its higher safety and excellent cycle performance compared with other anode materials. But the poor electronic conductivity limits its application. The current research on Li4Ti5O12 was summarized, and its development direction was proposed.
