在全固态陶瓷锂电池中实现了自组装固体电解质界面（SEI）上的快速电荷转移。在锂铝阳极和硫代lisicon （Li3.25Ge0.25P0.75S4）固体电解质之间施加电流形成SEI相。在SEI相自发形成后，界面电阻在充放电过程中波动并降至恒定值。呼吸界面有效地在电解质/电极边界处紧密接触，并促进固体界面处的快速电荷转移。自组装SEI阶段是界面设计的一般概念，将在所有固态电池的发展中发挥关键作用。(C) 2004。
Fast charge-transfer at the self-assembled solid electrolyte interface (SEI) has been obtained in an all-solid-state ceramic lithium battery. The SEI phase was formed between a Li-Al anode and the thio-LISICON (Li3.25Ge0.25P0.75S4) solid electrolyte by applying current though the cell. After the spontaneous formation of the SEI phase, the interfacial resistance fluctuated and decreased to constant values during the charge-and-discharge process. The breathing interface effectively makes a close contact at the electrolyte/electrode boundary and promotes fast charge transfer at the solid-interface. The self-assembled SEI phase is a general concept of interfacial design and will play a crucial role in the development of all solid-state batteries. (C) 2004 The Electrochemical Society.
