Texas A&M researchers have developed a new metal-free battery platform that combines organic chemistry and polypeptides, the building blocks of proteins, to produce sustainable, recyclable, non-toxic batteries as an alternative to present-day lithium-ion sources.

“By moving away from lithium and working with these polypeptides, which are components of proteins, it really takes us into this realm of not only avoiding the need for mining precious metals, but opening opportunities to power wearable or implantable electronic devices and also to easily recycle the new batteries. They [polypeptide batteries] are degradable, they are recyclable, they are non-toxic and they are safer across the board.”
