Evonik Unveils Printed Batteries; Seeks Partners

April 16, 2019 by Scott McMahan

Evonik debuted TAeTTOOz®, a new material technology for printable batteries, at the LOPEC trade show for printable electronics. The company used redox polymers developed by Creavis, the strategic innovation unit of Evonik to make TAeTTOOz.

Evonik says that the new materials can be processed by conventional printing methods into very thin, flexible battery cells, thereby providing a high degree of design freedom. The newly developed materials that make up the printable batteries are based on redox-active polymers. They allow for thin and flexible cathodes and anodes. Inkjet printers can use their specialized inks for anodes, cathodes and electrolytes to print metal-free, all-solid-state batteries on almost any substrate.

According to Evonik, they allow storage of electrical energy without the need for metals or metal compounds. Liquid electrolytes are not needed to make battery cells with the TAeTTOOz technology, therefore, they cannot leak.

Creavis is now seeking development partners to integrate the TAeTTOOz technology into new and existing applications.

Dr. Michael Korell, who is responsible for producing TAeTTOOz technology at Evonik, said, "We have developed a technology with enormous potential. It enables us to offer a solution to power small electronic circuits with printed batteries efficiently, reliably, and in an eco-friendly way."

The company says that TAeTTOOz technology enables new possibilities for the Internet of Things.

When ready for series production, the company expects that the technology could be used in many areas such as medical sensors for monitoring vital functions. Wearables with medical sensors could be worn far more conveniently when they use printed batteries. For logistics, intelligent sensors powered by printed batteries in packaging could monitor sensitive goods such as food or vaccines.
