Bendy Batteries a Step Closer

Korean researchers from the  Advanced Institute of Science and Technology  have found a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper. The researchers developed a graphene-based hybrid electrode and produced a flexible lithium rechargeable battery. The cathode material (V2O5) was grown on a graphene sheet using pulsed laser reposition and the anode was lithium-coated graphene.

This battery actually has promising performance compared to non-flexible batteries - higher energy density, power density and better cycle life. The team now works on extending the performance using solid-state or polymer electrolyte.
