提出了一种采用原位制备的正负极材料的全固态薄膜型可充电锂离子电池。采用OHARA公司生产的li2o - al2o3 - tio2 - p2o5基玻璃陶瓷的锂离子导电固体电解质片（OHARA片）作为固体电解质，夹在Cu和Mn金属薄膜之间。对Cu/OHARA片材/Mn层施加直流16V后成为全固态锂离子电池，电池工作电压为0.3 ~ 0.8 v，可逆容量为0.45μAhcm−2。通过对Cu/OHARA片材/Mn层施加直流高压，成功制备了高压电池，获得了工作电压在1.5 ~ 4.0 v的全固态电池。该工艺将成为开发先进的全固态可充电锂离子电池的新技术。
A novel all-solid-state thin-film-type rechargeable lithium-ion battery employing in situ prepared both positive and negative electrode materials is proposed. A lithium-ion conducting solid electrolyte sheet of Li2O–Al2O3–TiO2–P2O5-based glass–ceramic manufactured by OHARA Inc. (OHARA sheet) was used as the solid electrolyte, which was sandwiched by Cu and Mn metal films. The Cu/OHARA sheet/Mn layer became an all-solid-state lithium-ion battery after applying d.c. 16V to the layer, and the resultant battery operated at 0.3–0.8V with reversible capacity of 0.45μAhcm−2. High voltage battery was successfully prepared by applying the d.c. high voltage to a five-series of Cu/OHARA sheet/Mn layer, resulting in all-solid-state battery operating at 1.5–4.0V. The proposed fabrication process will become a new technology to develop advanced all-solid-state rechargeable lithium-ion batteries.
