FINANCIAL TIMES: Beyond lithium — the search for a better battery

Description

One area where there is a pressing need for battery innovation is in the emerging market for wearable technology. A rigid battery would not work in emerging areas such as smart clothing so academics have been developing more flexible models. Researchers at the University of Manchester in August revealed that they had developed technology using graphene-oxide to create an ink-like substance that can be printed on to fabrics. The ink, which is as flexible as cotton, acts as a solid-state flexible supercapacitor that can rapidly charge electronic components.
