A new type of flexible micro-supercapacitors

Researchers from Nanyang Technological University in Singapore build a new type of flexible supercapacitor that aims to be used in wearables and other portable electronics such as T-shirts charging mobile phones. The new type of capacitor is made with out-of-plane wavy structures of graphene micro-ribbons specially placed so that they don’t break when stretched while keeping the electrodes at a relative constant distance.

Graphene normally breaks when stretched but the team of researchers managed to place it in such a way that it can bend without any issue and without affecting it’s electrochemical performance. It’s too early to see this capacitor in commercial devices as it’s capacity is such that can only power an LCD for a minute, but improvement is possible.
