Solid State Battery Breakthrough May See Cellphones Last for Days

Simple changes to construction makes Cellphone Batteries both Safer and to have Longer Lasting Storage Capacity

Known as solid-state batteries, these experimental devices could greatly extend the life of electric vehicles and mobile devices by significantly upping the energy density packed inside. Scientists at MIT are reporting an exciting advance toward this future, demonstrating a new type of solid-state battery architecture that overcomes some limitations of current designs.
