All-solid-state Batteries

Wide discharge temperature range

Discharging in a discharge temperature range from low temperature of -50 deg. C to high temperature of +125 deg. C, that existing lithium-ion batteries cannot handle, is now possible.

Enhanced durability and endurance^∗1

Maxell’s all-solid-state batteries have enhanced durability and endurance, which was difficult to achieve with existing batteries. As they can reduce the need for frequent maintenance such as battery replacement, they can contribute to infrastructure monitoring in harsh environments and measures against decrease in the working population.

High capacity and high output^∗2

Discharge at a high rate is made possible by adopting sulfide-based solid electrolytes with high ionic conductivity. Devices can thus be converted into IoT devices such as real-time-monitoring instruments with low-power-consumption wireless communication including Bluetooth^® Low Energy, LPWA, etc.

No liquid leakage, explosion, or ignition

There are no concerns such as liquid leakage, explosion, or ignition, so high safety^∗3 is a feature of the batteries. We also envision use in the medical and healthcare fields where safety, in addition to use in harsh environments, is a requirement.
