Flexible Battery Technology Hits Highest Density Yet

Flexible Battery Technology Hits Highest Density Yet

New flexible battery technology from researchers at the Korea Advanced Institute of Science and Technology (KAIST) has hit the highest energy density yet for this type of battery. The bendable, thin-film, lithium-ion battery could be used in things like e-paper, wearable electronics and improved piezoelectric devices for harvesting energy from movement. Imagine flexible gadgets that could be powered by bending them. Up until now, these thin-film batteries have employed flexible organic materials that were low performing or polymer binders that were too bulky and limited the battery's density. The new battery developed by the KAIST researchers uses inorganic thin films that have a high energy density and, according to the KAIST team, performs just as well as bulk batteries. Gizmag reports : The batteries are built by sequentially depositing several layers – a current collec...
