Nickel, negative electrode active material are metal oxide, also referred to as hydrogen-storage alloy, and electrolyte is potassium hydroxide.When charging, hydrogen is precipitated in cathode
Gas, in a reservoir, anode becomes nickel hydroxide (NiOOH) and H2O by hickelous nydroxide for storage；Hydrogen quilt on cathode when electric discharge
It consumes, anode becomes hickelous nydroxide by nickel hydroxide.
Due to being sealing structure inside Ni-MH battery, temperature increases and causes air pressure liter in battery in battery discharge procedure
Height, while phenomena such as overcharge can also cause in battery air pressure to increase, and be likely to result in battery explosion, hair rises, leakage, causing
Serious security risk.
Utility model content
In view of the above problems, the utility model provides a kind of Ni-MH battery that voltage stabilizing is explosion-proof, to solve since temperature is excessively high
Or the excessively high problem of air pressure in caused battery when overcharge.
To achieve the above object, the utility model solves by the following technical programs：
A kind of Ni-MH battery that voltage stabilizing is explosion-proof, including battery core, be wrapped in the battery core shell, be placed in the shell

The utility model has the beneficial effects that：
First, battery temperature in the process of charging and discharging, battery increases, and causes air pressure in battery to rise, excessively high gas
Pressure may make battery explosion, hair rise, leakage phenomena such as.For this purpose, be arranged between negative plate and shell there are one voltage stabilizing shell,
Voltage stabilizing shell upper end is provided with pars contractilis, and when air pressure increases in battery, pars contractilis moves up in cavity, is carried to inside battery
For space, to reach pressure balance.
Second, pars contractilis is in rugosity, and the material of pars contractilis is temperature sensing material, and in battery high-temperature, temperature sensing material relaxes
Expansion, under the action of interior pressure, can easily be moved up.
