Nickel-metal hydride(Ni-MH)

Nickel-metal hydride rechargeable cell consists of the positive plate containing nickel hydroxide and the negative plate containing metal alloy capable of absorbing and desorbing hydrogen. The electrolyte is combination solution of potassium hydroxide and lithium hydroxide. Ni-MH rechargeable cells have excellent discharge performance under low temperature. Even the Ni-MH cells are discharged with large current (i.e. 1C discharge current) under -20℃, the output power can reach to 85% of nominal capacity. In addition, the capacity loss caused by the self-discharge on high temperature ( especially above ＋40℃) is restorable. The cell capacity can be restored to the normal capacity after several times of charge-discharge cycles.

Changhong sealed cylindrical Ni-MH rechargeable cells are specifically designed for professional electronics tools, medical care equipments, portable radio communication  and signaling equipments, flashlights, diving and mining lamps , shavers, electric toys and more consumer electronic products.

Changhong high power Ni-MH rechargeable cells are in prismatic shape , which are widely applicable for electric and hybrid vehicles, AGV, E-bikes, E-scooter, electric wheelchairs, , DC power supply for telecom network, UPS, DC distribution system and switch gear, back-up power supply for emergency and public security systems.

Changhong could provide custom-designed and standardized Ni-MH battery packs to meet specific requirements on external dimensions and system voltage.
