Maxell Has Developed High-capacity Products with Twice the Capacity of the Current “Air Patch Battery II” Series
Twice the capacity of existing products*2 enables application in a wider range of field
Maxell, Ltd. (President and Representative Director: Keiji Nakamura / hereinafter “Maxell,”)has developed high-capacity products with twice the capacity*2 of the current “Air Patch BatteryII” series of high-output*3 thin flexible batteries, which can be used for long periods*4 with consideration for safety and environmental impact.
The “Air Patch Battery II”, which Maxell announced on May 19, 2022, is suitable for logistical management tags that manage item location information, usage status, temperature, humidity, etc., in addition to medical/healthcare patches used for monitoring biological information such as body temperature and blood glucose levels, as well as administering drugs such as insulin and pain relievers. A doubling of the high capacity of existing products*2 is accomplished by combining and further evolving safety technology with the battery material and manufacturing technology that Maxell has cultivated over half a century through button, coin, and small laminated batteries for IoT and wearable devices. Adding this battery to the lineup can support more information monitoring and long-term use.
“Air Patch Battery II” is currently being shipped for samples, and mass production is planned for fiscal 2024.
Maxell will continue to evolve its technologies for safety and environmental impact reduction while working on the development of safe, secure, high-performance batteries
