First fully printed rechargeable batteries for printed sensors

InnovationLab has announced a partnership with AIPIA member Evonik that will enable the first fully printed, flexible, rechargeable, solid-state, batteries for integration in printed sensor systems, they claim. 

It involves combining TAeTTOOz, printable battery materials from Evonik, and InnovationLab’s  capability for high-speed printed electronics. The two companies said they are opening new application areas to ultra-thin printed batteries that are more flexible, safer and more environmentally friendly than traditional metal-based batteries, according to the report in Printed Electronics Now.

This set of materials enable the printing of ultra-thin, metal-free, all-solid-state batteries on flexible substrates. The collaboration facilitates high-speed production of safer, rechargeable batteries in conformal shapes that fit naturally with fitness wearables, medical diagnostics and smart labels for food packaging, supply-chain logistics, and other applications, the partners said.

“Through our partnership with Evonik, we can now produce the first fully printable rechargeable battery using our volume-production printing process,” said Dr Christoph Kaiser, head of Tech-2-Market department at InnovationLab. “Because the Evonik material isn’t charged during the production process you can power up the battery after printing, which means you can produce them in standard production facilities instead of a specialized environment, saving considerable costs.“ 

“We’ve also pioneered the easiest way to build up a rechargeable battery that’s not comprised by contaminants, making it the greenest of all battery platforms. It’s both easy to produce these new light and thin batteries, and it’s easy to dispose of them,” he added.

 “Unlike traditional batteries, TAeTTOOz is a brand-new material technology that uses our patented redox polymers instead of metal or metal compounds,” explains Dr Michael Korell, head of new growth area energy storage at Creavis, the strategic innovation unit of Evonik. “That unique attribute delivers many benefits. Being free from liquid electrolytes batteries made with TAeTTOOz cannot leak.”
