Hybrid Aqueous Battery Charges Faster

Hybrid Aqueous Battery Charges Faster
Mar-02-18
A hybrid aqueous energy storage device that can be recharged in under a minute could have applications in portable electronic devices.

Developed by a team from KAIST, the device replaces typical flammable organic solvents with a liquid electrolyte placed between an anode made of graphene-based polymer chain materials and a cathode consisting of graphene embedded with nickel oxide nanoparticles. According to the team, the eco-friendly design offers a much higher energy and power density than previous aqueous designs, and can be charged in about 30 seconds via a low-power charger such as USB.
