| Abstract Scope |
Co-fired all-solid-state lithium-ion battery with multilayer ceramic technology attracted attention as safe power sources in the field of small devices such as IoT, wearable devices, and medical applications. Multilayer ceramics technology enables to make thin solid electrolyte layer down to sub-micron order, which can cover low ionic conductivity of solid electrolyte by its thickness control. Also, since it is easy to make parallel connection of battery inner structure, capacity and inner resistance can be controlled by the number of layers. In addition, this technology leads to high volume manufacturing by using similar manufacturing equipment for multilayer electronic components such as multilayer ceramic capacitor. This presentation will describe key points of material selection and process electrode structure optimization to make co-fired all solid battery with multilayer ceramic technology. |
