Nickel -metal hydride battery characteristics

　　1. Large capacity

　　The "energy storage density" of nickel -metal hydride batteries can be charged batteries as an example. At least 1000mAh or more, good ones can reach 1400mAh. Under the same volume and weight conditions, its capacity is the nickel -cadmium battery. 2 to 3 times, and more than one times more than traditional nickel -cadmium batteries.

　　2. No "memory effect"

　　Nickel -metal hydride batteries have no "memory effect", but during use, there is a self -discharge phenomenon. Under normal use cases, the amount of power loss is 1 % to 3 % per day. Nickel -metal hydride batteries full of charged. After being placed for a few weeks, they must be recharged. Since nickel -metal hydride batteries have no "memory effect", they do not need to be discharged before they start charging. They can be charged with any charging.

　　3. Strong ability to charge and discharge

　　Nickel -metal hydride batteries are charging and discharge. Even if it is charged, it will not cause permanent damage to the battery. After the battery is discharged to 0V, the power can still be restored.

　　4. No pollution

　　Because the ingredients of cadmium in nickel -metal hydride batteries are extremely micro -cadmium or even without cadmium, it will not pollute the environment. Therefore, nickel -metal hydride batteries are also called environmentally friendly batteries or "green batteries". Many countries have invested heavily in the construction of nickel -metal hydride battery production lines.

　　5. Rich resources

　　The hydrogen storage alloys used in nickel -metal hydride batteries are extracted from rare earth, and my country is a large country of rare earth resources, accounting for about 80 % of the global total storage volume. Therefore, the development of nickel -metal hydride batteries in my country has a unique advantage.

　　6. Life long

　　Nickel -metal hydride batteries are used for 1C current charging and discharge cycle. The service life of 0.2C current charging and discharge cycle has exceeded 1,000 times. From the perspective of actual service life, the No. 5 nickel -metal hydride battery is used as an example. It can be reused 1000H.
