Batteries are a necessity for today's mobile devices and battery technology is on a feverish pace to keep up with the cutting edge demands. First there was the lithium-air, sodium-ion, lithium-ion and the aluminum-ion. These are still being improved but the have not yet fulfilled the stringent requirements.

The Korean Advance Institute of Science and Technology (KAIST) has thrown their entry into the ring with a liquid electolyte sandwiched between an anode and a cathode. The anode is composed of a polymer based on graphene giving it a high surface area. The cathode is made up of nickel oxide nanoparticles embedded on graphene.

The new materials give the battery a much higher energy density and faster energy exchange over other aqueous battery designs. It proved to be far more stable and exhibited lower energy loss.

This new design and the incorporation of the new materials, has improved the power density by about 100 times higher and allows it to be charged in 20 to 30 seconds using a low power USB connection.
