钛酸锂材料表面改性研究

Modification research of lithium titanate material surface

进行了钛酸锂表面改性方面的工作,针对钛酸锂材料碱性高的问题,通过酸处理后,考察了不同p H值条件下的钛酸锂,并通过扫描电子显微镜法(SEM)、X射线衍射光谱法(XRD)、循环伏安法(CV)等进行了分析,采用软包装505456电池测评,电池在产气方面得到较大程度的降低和抑制。

The modification research work of lithium titanate material surface was performed. The PH value of lithium titanate was high and it was modified to lower PH with acid. It was analyzed with SEM,XRD,CV. The performance of modified material was evaluated by 505456 type. The swelling of battery was showed to lower and restrained at a large extent.
