固态电解质是开发全固态锂二次电池的关键，与现有的液体锂离子技术相比，固态电解质具有安全优势。为了验证高能球磨法制备的li6ps5cl基固体电解质的使用效果，实现了以LiCoO2和Li4Ti5O12为活性材料（AM）的全固态电池。通过优化电极组成，LiCoO2和li4ti5o12基半电池每克复合材料的最大容量分别为46和27 mAh。组装的全固态LiCoO2/Li6PS5Cl/Li4Ti5O12电池具有每克AM 27 mAh的持续可逆容量和接近99%的库仑效率。(C) 2013 Elsevier B.V.版权所有
Solid-state electrolytes are being intensively explored as the key to develop all-solid-lithium secondary batteries which present safety advantages over present liquid Li-ion technology. To validate the use of the Li6PS5Cl-based solid electrolyte obtained by high energy ball milling, all-solid-state batteries using LiCoO2 and Li4Ti5O12 as active material (AM) have been realized. The optimization of the electrode composition led to a maximum of 46 and 27 mAh per gram of composite for LiCoO2 and Li4Ti5O12-based half-cells respectively. The assembled all-solid-state LiCoO2/Li6PS5Cl/Li4Ti5O12 battery presents a sustainable reversible capacity of 27 mAh per gram of AM and a coulombicic efficiency close to 99%. (C) 2013 Elsevier B.V.
