This kind of battery refers to the black gold high-energy battery introduced by Wei Chao Group, which uses graphene in the grid of the battery.

After three generations of product upgrades, the grid structure, curing process and electrolyte acid ratio of black gold battery have been optimized and upgraded.

Compared with the first generation black gold battery, the upgraded black gold battery has improved and upgraded the core technology of graphite dilute alloy on the basis of the first generation, and has a unique "constant electrode column" structure, which makes the product more stable in performance, longer in service life and farther than ordinary batteries.
