The using life of this battery is longer than other batteries, the working life is determined by the negative pole material (ABs, AB2, AB5, A28 and so on)
Hydrogen storage alloy is easily oxidized after repeatedly charging and discharging. this is the main reason which affects the battery life. In order to prevent the occurrence of this phenomenon, we could adjust the hydrogen-absorbing alloy components, or use coating methods. The main function of coating is:
(1) prevent surface oxidation and passivation, to improve the cycle life of the electrode;
(2) improve the electrical conductivity and thermal conductivity.
No matter AB5 type or AB2 type alloys, in order to improve the electro-chemical properties, people often used method of heat treatment. Heat treatment method is easy to operate, low cost, and has remarkable results, the effects are as follows:
① eliminate certain impurities;
② improve the utilization of hydrogen storage;
③ improve the discharge capacity, prolonged cycle life of charging and discharging
Long-life batteries have the following characteristics
1. it has good deep cycling capability, with good capacity of overcharge and over discharge.
2. long life, a special process ensure the long-life of this battery.
3. adapt different applicable environmental requirements
