Although flexible and wearable gadgets are the next major
trend in electronics, limitations on the power source have yet
to be overcome. Hence, a new type of flexible lithium batteries
has been developed by using metallic textiles. These flexible
batteries can withstand complex and harsh wear conditions, e.g.
repeated folding and twisting. They have achieved a high energy
density, excellent cyclic stability (>80% capacity retention after
500 cycles) and remarkable bending stability at small bending
radius (<1 mm). Proved to be penetration and impact safe,
they are highly reliable and safe to use. Flexible textile lithium
batteries can be potentially used to power portable or wearable
electronics, flexible electronics, components of Internet of Things
(IoT), medical accessories, etc.
