Maxell Develops Coin Type All-Solid-State Battery “PSB2032” Suitable for Main Power Supply for IoT Devices

Samples to be available in late December 2025

Since developing coin type all-solid-state battery in 2019, Maxell has been advancing research and development of all-solid-state batteries of various types, including ceramic package type, bipolar type, and cylindrical type. The newly developed “PSB2032” delivers a capacity of 35 mAh - approximately four times that of the ceramic- packaged “PSB401010H” currently in mass production, making it suitable for use as the main power source for IoT devices.
The “PSB2032” incorporates key features of Maxell’s all-solid-state batteries, such as a wide discharge temperature range, high reliability, and high safety, while maintaining the high sealing capability equivalent to ceramic-packaged models. In addition, while the “PSB401010H” is suitable for reflow mounting, the “PSB2032” samples come pre-equipped Coin Type All-Solid-State Battery “PSB2032” (Sample) with connection terminals*3 suitable for mounting into small-sized devices, enabling Maxell’s all-solid-state batteries to accommodate different mounting methods.
