High-Power, Coin-Sized Battery Cells For Portable Electronic Devices

It offers numerous possibilities for future development of wireless and mobile gear, facilitating production of increasingly compact devices

The printed battery market is considered to be one of the fast-growing markets. And to aid the production of thin, flexible and attachable battery cells that enable new business models and applications, VARTA has optimised the cell design of the lithium-ion series to come up with the new CoinPower A4 generation that provides high energy density.

Moreover, with the help of optimised electrodes, higher compression and a new electrode balancing for higher charging voltage, a wider voltage window is achieved. The A4 generation includes seven different cell types with a diameter of 9.4 x 16.1 mm and capacities of 29 to 155 mAh.

The new CoinPower A4 generation provides numerous possibilities for future development of wireless and mobile gear in a wide range of application areas. The lithium-ion button cells empower independence from wireless headsets, medicals to measuring and security systems as well as automotive to Industry 4.0 applications.
