What Is the Electrochemical Principle of Ni-MH Battery?

Ni-MH batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and lye (mainly KOH) as the electrolyte.

When the nickel-hydrogen battery is charged:

Positive electrode reaction: Ni(OH)2 + OH- → NiOOH + H2O–e-

Negative reaction: M+H2O +e-→ MH+ OH-

When the Ni-MH battery is discharged:

Positive electrode reaction: NiOOH + H2O+e- → Ni(OH)2 + OH-

Negative electrode reaction: MH+OH- →M+H2O+e-

As a lithium battery company, we are growing rapidly with annual sales of more than 30% in a rapidly changing market.

In order to meet the ever-expanding customer demand, we have adopted a variety of supply channels, self-production and outsourcing production, setting up warehouses close to customers and other forms.
