Printed batteries are core elements in fully printed electronic modules.
They are approached in different battery chemistries and production processes. Zinc-Manganese Dioxide batteries are the simplest and environmental friendliest ones.
Capacities of primary cells go up to few mAh per square centimeter.
The available current is strongly dependent on the available battery area.
But also secondary cells could be produced in printing processes, however, the process is more complex and the chemistry needs more optimisation.
Mainly the chemical systems of lithium cells, developed during the last years, are used for secondary cells.
Single cells deliver 1,5 Volts. Via integrated design, a series of connected cells could deliver multiples of 1,5.
The printing process offers the opportunity to print the battery in nearly every possible shape. Full customization to the application is possible.
This outstanding ability of printed electronics creates also one of the main differences between printed batteries and conventional batteries: no standard form, but printed batteries fit in every application
The thickness depends partly on the specific capacity but has a minimum of 0,6 mm.
