Hitachi, Ltd. (TSE: 6501) and Tohoku University's Advanced Institute for Materials 虎扑电竞 (AIMR) have developed a basic technology to reduce the internal resistance of the all-solid-state lithium ion battery (Li-ion battery) using a complex hydride*1 as a solid electrolyte.
The reduction of internal resistance improves the charge-discharge performance of the all-solid-state Li-ion battery, resulting in the batteries (capacity: 2 mAh) successfully operating at temperatures as high as 150°C, with a discharge capacity of 90% of theoretical value*2.
This technology is significant as it allows the thermally durable Li-ion battery to be used in a wider variety of applica
