钛酸锂电池热失控安全性研究

Thermal Runaway Safety of Lithium Titanate Battery

本次测试对钛酸锂电池进行过充、针刺、电池挤压、加热这四种滥用方式下的热失控触发实验,通过分析数据来获取其电气安全、机械安全以及热安全性能。实验结果显示,在针刺、挤压等机械滥用条件下,钛酸锂电池表现出良好的抗滥用风险能力,仅在过充场景中则发生较为剧烈的热失控反应。表明钛酸锂电池的安全性更高,有效降低了因滥用引发起火或爆炸的可能性。

In this test,the thermal rumaway tiggering experiment of lithium titanate battery under overcharge.acupuneture,extrusion and heating is carried out,and its electrical safety,mechanical safety and themal safety performance are obtained by analyzing the data.The experimental resuls show that under the conditions of me-chanical abuse such 85 acupuneture and extrusion,lithium titanate battery shows good anti-abuse risk ability,and more severe thermal runaway reaction occurs only in the overcharge scenario.It shows that lithium titanate battery has higher safety and eectively reduces the possibility of fire or explosion caused by battery abuse.
