The gaming headsest battery's cell the posiive electrode uses a three-dimensional hvbrid conductor composed of few-walled graphene, few-walled carbon nanotubes, and superconductina black, while the negative electrode uses a mixture of few-waled carbon nanotubes and super conducting carbon black as the conductive material.Meanwhile, electroly wetting agents are incorporated into the electrodes. This approach increases the volumetric energy densily of the battery by 4% compared to batteries of the same size, stll maintaining excellent cycle life and fast charging capability.

The battery's cell capacity is higher, Longer use time. reduce frequent change the cell, reduce environmental polution, more environmental protection.
