Application of Lithium Titanate Battery in Industrialization of Urban Transit Electric Vehicles

摘要: 近年来，钛酸锂电池由于具有长寿命、安全的特点而引起人们极大的兴趣。用固相合成法合成的钛酸锂材料颗粒在几十到几百纳米之间，电池的充放电平台电压为1.57 V；采用钛酸锂作为电池负极，采用三元材料为正极制造的电池，在不同充放电倍率、大倍率和高温条件下分别做了测试，发现电池具有较高的性能；电池首次在重庆得到大规模应用，测试了电池的典型工况、充电电流、充电时间与能耗水平，证明钛酸锂负极电池可应用与城市公交电动化中具有较高的市场前景。

Abstract: The great interest for lithium titanate battery with features of long life and safety has grown in recent years. Lithium titanate material particles ranging from dozens to hundreds nanometer in diameter were prepared using solid phase synthesis method; voltage of the charge and discharge platform was 1.57 V. Using lithium titanate as battery cathode and ternary materials as anode, tests were made under different charge-discharge rates, zoom time and high temperature respectively, indicating that the battery offers higher performance. This battery has been put into large- scale application in Chongqing, and typical operating conditions, charging current, recharging time and energy consumption level were tested, proving that lithium titanate battery has a promising market prospect of application in industrialization of urban transit electric vehicles.
