Submission + - Supercapacitor Breakthrough Rivals Batteries (physicsworld.com)

MojoRilla writes: US researchers have developed supercapacitors that have the same storage per weight as nickel metal hydride batteries, but can be charged and discharged much faster. Their goal is to develop a supercapacitor with stores as much energy as the best Lithium Ion batteries, but can recharge in two minutes. As with any new technology, there are still hurdles to commercialization, but maybe we'll be able to recharge our IPhone 8s while brushing our teeth.
