Air Patch Battery (Under Development)
Air Patch*1 Battery is a thin flexible battery made with consideration for safety and environmental impact using no hazardous or dangerous materials.
It comes in a more environmental load and safety conscious type (AP), and a high-power*2 type (AP II) that can be used for long periods of time*3 to meet our customers’ requests.
Air Patch Battery is suitable for 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, in addition to logistical management tags that manage item location information, usage status, temperature, humidity, etc.

Features
Does not use hazardous or dangerous materials
Hazardous or dangerous materials, such as mercury, lead, cadmium, lithium metal, potassium hydroxide (strong alkali) , and flammable organic solvents, have not been used.
Disposable
The battery can be disposed after use.*
* Please dispose of in line with the appropriate local and/or national guidelines.
Lightweight, thin and flexible
Comfortable even when attached to your body and available for thin devices and curved surfaces.
High capacity and high energy density
Two to five times or more as high as a manganese-zinc sheet battery with typical aqueous electrolyte solution.*
* Volumetric Energy Density (depending on battery size), according to a June 2023 Maxell survey
Extensive product lineup that supports a wide range of applications
Maxell has been developing Air Patch Battery, thin and flexible battery which does not use hazardous or dangerous materials, with the aim of reducing the environmental load.
There are two types of lineups to support a wide range of applications, based on the development of materials that can bring out battery performance effectively with due consideration to environmental load and safety.
- Air Patch Battery (AP) series made with increased consideration for environmental load and safety
- Air Patch Battery II (AP II) series suitable for long-term use*3 featuring high output*2 characteristics
Applications
Air Patch Battery is suitable for a power source of a wide range of applications, such as logistics control tags that manage locational information, usage conditions, temperature and humidity, as well as skin sensors and medical/healthcare devices.
- Medical and healthcare patches (medical sensing, drug delivery)
- Logistics control tags (location, usage conditions, temperature and humidity)
- IoT and wearable devices
- Disposable devices*
* Please dispose of in line with the appropriate local and/or national guidelines.
- Air Patch: Registered trademark of Maxell, Ltd. in Japan. Registration No. 6142395
- High power/High output: When AP II 082530 is discharged with a current of 50 mA (maximum discharge peak current) for 10 msec at intervals of 3 sec at 20 deg. C. This depends on usage conditions and battery product name (typical capacity).
- Can be used for long periods of time/Long-term use: 1 year of use, when AP II 082530 is used with a load of average current consumption of 2 μA at 20 deg. C. This depends on storage conditions, usage conditions, and battery product name (typical capacity).
