“PSB401010T” incorporates the technology that enables all-solid-state batteries to operate at temperatures up to 150℃^*1 announced in 2024, along with the features of “PSB401010H,” currently mass-produced at Maxell, a wide discharge temperature range, high reliability, and high safety^*2.

“PSB401010H” can be used in high-temperature environments that conventional lithium-ion batteries cannot operate in, making it suitable for industrial equipment, data loggers, and RTCs (real-time clocks) used in high-temperature environments. In addition, as sample evaluations by customers are progressing in a variety of fields, we have received many requests for further improvement in the maximum discharge temperature.

In response to these needs, we have been advancing development toward commercialization and will begin the sample shipment of “PSB401010T” in November.

The newly developed “PSB401010T” has improved the cycle life, a key indicator of battery longevity, to approximately five times^*1 compared to “PSB401010H”, in the 150℃ environments.

By using “PSB401010T” in equipment that operates in high-temperature environments, it is expected that the operational time of the equipment will be extended compared to when conventional batteries are used.

Maxell will continue to utilize the Analog Core Technologies to solve many social issues, and we will proceed with the development of all-solid-state batteries and modules, leveraging four　key features: long lifetime, high temperature resistance, high output, and high capacity, to be applicable in areas not useable with existing batteries.
