In resent years, lithium titanate has become one of the most attractive anode materials for lithium-ion batteries owing to the zero-strain effect, stable charge and discharge platform, and excellent cycle stability. 钛酸锂作为近年来研究较热的锂离子电池负极材料之一,具有零应变效应、平稳的充放电平台、良好的循环稳定性等特点。
Recently, the main source of titanium for preparation of lithium titanate material is rutile TiO2 and titanium organic compounds. 目前,制备钛酸锂材料的钛源主要是Ti02和钛的有机化合物。
TG/ DSC and X-ray diffraction results indicate that the pure phase lithium titanate could be easily obtained using lithium acetate dehydrate and TiO2 as raw materials compared to other lithium salts under the same condition. 不同前驱体混合物的热分析结果及产物的X-射线衍射图谱表明,以乙酸锂和二氧化钛为原料时,在相同合成条件下能较容易得到纯相的尖晶石钛酸锂。
Furthermore, by comparing the test results of lithium cobalt oxide and lithium titanate battery, it was found that, thermal stability of lithium titanate battery is significantly higher than that of commercial widely used lithium cobalt battery. 此外,通过对钴酸锂电池和钛酸锂电池的绝热循环产热数据进行对比,发现钛酸锂电池的热稳定性要明显高于目前商业广泛使用的钴酸锂电池。
Therefore, lithium titanate battery may be an appropriate choice for areas with high security requirements. 因此,对于对安全性要求较高的领域,钛酸锂电池更具有优势。
