Development of “Air Patch*1 Battery II” thin high-capacity flexible battery

This doubling of the capacity of existing batteries^*2 has been achieved by combining safety technology with battery materials and manufacturing expertise gained over half a century through the production of button, coin, small laminated batteries for IoT and wearable devices. By adding this battery to the lineup, Maxell can support more information monitoring and long-term use.

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. When it comes to medical and healthcare application where safety is paramount, the Air Patch II battery can be used within patches used for monitoring biological information such as body temperature, blood glucose levels as well as administering drugs such as pain relief or insulin.

Battery technology plays a crucial role in our modern world, and advancements like these can have a positive impact on a variety of industries and contribute to sustainability efforts. Maxell is committed to evolving our technologies with a focus on safety and environmental impact reduction.  

“Air Patch Battery II” is currently being shipped for samples, and mass production is planned for fiscal 2024.

*2 Twice the capacity of existing products / high-capacity products with twice the capacity / the high capacity of existing products: AP II 112530 (with twice the capacity of existing product AP II 082530), and AP II 115055 (with twice the capacity of existing product AP II 085055). AP II was announced on May 19, 2022 through the press release “Maxell Adds new lineup to Air Patch Battery for Medical, Healthcare Services, and Logistics.” (https://ssl4.eir-parts.net/doc/6810/ir_material4/185935/00.pdf)
*3 High output: When AP II 112530 is discharged with a current of 50mA (maximum discharge peak current) for 10msec at 3sec intervals at 20 °C. This depends on usage conditions and battery product name (standard capacity).
*4 used for long periods: 1 year of use, when AP II 112530 is used with an average current consumption load of 4μA at 20 °C. This depends on storage conditions, usage conditions, and battery product name (standard capacity).
