Safer and Flexible Lithium Ion Batteries: Dream or Reality?

Lithium ion batteries are the key components of the portable, entertainment, computing and telecommunication equipment required by today's information-rich and mobile society. Highly flexible batteries would free product designers from the constraints of rigid and predetermined forms. In addition, powerful and light-weight batteries made from inherently safe materials could facilitate quickly advance development of electric vehicles and other transportation applications. In this mini-review, some advances on flexible and light-weight batteries are reported and discussed.
