New battery technology: printable, ultra-thin and environmentally-friendly
The new battery technology opens up new areas of applications for ultra-thin rechargeable sheet batteries that are more flexible, safer and more sustainable than conventional batteries that use metals.
InnovationLab and Evonik combine the advantages of TAeTTOOz, Evonik’s printable battery materials, with the capacity of InnovationLab’s high-throughput manufacturing of printed electronics. TAeTTOOz is a new material technology for printable batteries. The materials based on so-called redox polymers can be processed to very thin flexible battery cells as part of conventional printing methods. This makes it possible to store electrical energy without having to use metals or metal compounds.
Thanks to our partnership with Evonik, we are now able to manufacture the first fully printable rechargeable battery in mass production”, explained Dr. Christoph Kaiser, Head of Tech-2-Market at InnovationLab. “This is immensely beneficial for customers. Evonik’s material won’t be charged during the manufacturing process, but instead after printing.”
This means manufacturing is possible in a standard production plant without the need for specialist environment, thus saving substantial costs. We have also found the most simple way to develop a rechargeable battery that’s free from emissions and consequently more sustainable than other battery platforms. These new light and thin batteries are simple to produce and just as simple to dispose of.”
“Unlike conventional batteries, TAeTTOOz uses a completely new material technology – patented redox polymers intead of metal or metal compounds”, said Dr. Micael Korell, Head of New Growth Area Energy Storage at Creavis, Evonik’s strategic innovation unit.
“These unique characteristics offer many benefits: The batteries manufactured with TAeTTOOz® technology do not require liquid electrolytes and are therefore leak-proof. Our material set enables ultra-thin, metal-free solid-state batteries to be printed on flexible substrates. Our collaboration with InnovationLab illustrates the benefits of this approach. It enables high-speed production of safe, rechargeable batteries with form factors that are tailor-made for use in fitness wearables, medical diagnostics, smart labels for food packaging, delivery logistics and other applications."
