InnovationLab acquires flexible printed battery technology from Evonik

InnovationLab, the expert in printed electronics "from lab to fab", announces that it has acquired the TAeTTOOz printable battery technology from Evonik. InnovationLab and Evonik have been close partners in this field for many years and have jointly driven the technological development of TAeTTOOz to the present threshold of industrial scale production.

TAeTTOOz is the first technology of its kind that enables flexible, rechargeable solid-state batteries to be printed at industrial scale. These ultra-thin, printed batteries are far more flexible, safer and more environmentally friendly than traditional metal-based batteries. Typical applications are set to include low-cost IoT sensor labels for packaging and stock management, wireless industrial sensor technologies, and self-powered signage solutions.

TAeTTOOz technology can also be used with energy harvesting components to create self-powered signage, packaging and other innovative devices. For example, the technology has already been successfully applied in conjunction with printed organic photovoltaic (OPV) solar cells.

TAeTTOOz is based on redox-active polymers and can be processed using conventional printing methods to produce thin, flexible battery cells, which enable electrical energy to be stored without the need for metals or metallic compounds. Furthermore, battery cells based on TAeTTOOz technology do not require liquid electrolyte to function, which inherently eliminates the risk of leakage and any resultant hazards.

The battery is not charged during production, so no extra handling precautions are needed, and it can be produced on standard printing presses. As the battery does not hold any voltage before its first charge, follow-up processes like picking and placing of components are possible, without the risk of damaging the components by overvoltage.
