Maxell to Begin Sample Shipment of 150℃-Compatible Ceramic-Packaged All-Solid-State Battery “PSB401010T” in November

“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.

“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.
“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 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.
