If the micron-level nickel powder is replaced with nano-scale nickel powder, and an appropriate process is added, an electrode with a huge surface area can be manufactured, so that the specific surface area participating in the nickel-hydrogen reaction is greatly increased, which makes the power of the nickel-hydrogen battery Increase several times, greatly improve the charge and discharge efficiency. In other words, if the nickel nickel powder replaces the traditional nickel carbonyl powder, the size and weight of the nickel-metal hydride battery can be greatly reduced without changing the battery capacity.

This kind of nickel-metal hydride battery with large capacity, small size and light weight will have wider applications and markets. Nickel-metal hydride batteries are currently the safest, most stable, and cost-effective green batteries in secondary rechargeable batteries.
