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.
