SULFIDE-BASED ALL-SOLID-STATE LITHIUM SECONDARY BATTERY SYSTEM

摘要

In an all-solid-state lithium secondary battery provided with a layer containing a sulfide-based electrolyte, the generation of hydrogen sulfide is effectively suppressed without degrading the battery characteristic. A battery system (100) is provided with an all-solid-state lithium secondary battery (1) which uses a sulfide-based solid-state electrolyte material, and a reducing means (2, 3, 5) for reducing the amount of charge/discharge of the all-solid-state lithium secondary battery when the temperature inside the all-solid-state lithium secondary battery reaches a first threshold value.
