Nickel-metal hydride batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and alkaline solution (mainly KOH) as the electrolyte, when charging nickel-metal hydride batteries:

Positive reaction: Ni(OH)2 + OH- → NiOOH + H2O-e-
Negative reaction: M+H2O +e-→ MH+ OH-
Nickel-metal hydride battery discharge:
Positive pole reaction: NiOOH + H2O + e- → Ni(OH)2 + OH-
Negative reaction: MH+OH- → M+H2O+e-

It refers to the internal air pressure of the battery, which is caused by the gas generated by the sealed battery during the charging and discharging process. It is mainly affected by factors such as battery materials, manufacturing processes, and battery structure. The main reason is that the gas generated by the decomposition of moisture and organic solutions inside the battery accumulates in the battery. Generally, the internal pressure of the battery is maintained at a normal level. In the case of overcharge or over-discharge, the internal pressure of the battery may increase:
For example, overcharge, positive electrode: 4OH- - 4e → 2H2O + O2↑;
①The generated oxygen reacts with the hydrogen precipitated on the negative electrode to form water 2H2 + O2 → 2H2O
②If the speed of reaction ② is lower than the speed of reaction ①, the oxygen produced will not be consumed in time, which will cause the internal pressure of the battery to increase.
