Nickel metal hydride rechargeable batteries and nickel-cadmium batteries which good?

by:dcfpower     2020-12-12

still more familiar with guys now for nickel metal hydride rechargeable batteries, nickel metal hydride rechargeable batteries on the environment pollution-free, no memory effect. Nickel metal hydride rechargeable batteries are much expensive price disadvantage is that the nickel cadmium battery, nickel metal hydride rechargeable batteries in the invention, the nickel cadmium battery already occupied very big one part of the battery industry market, has also been industry market. But after invention nickel metal hydride rechargeable batteries, the nickel cadmium battery market position and a short time, is this why? Don't heralding the nickel cadmium battery too much far worse than that of the nickel metal hydride rechargeable batteries, abandoned by the new era? This situation? Then follow us battery small make up way to discuss!

a, the situation of the nickel cadmium battery

nickel cadmium battery ( 镍- cadmiumbattery) Key to the positive active material made of nickel, the cathode active material key produced by cadmium and become a kind of typical alkaline storage battery. Is extremely nickel hydroxide, negative extremely cadmium, the electrolyte is potassium hydroxide solution for the nickel cadmium battery, normal maintenance is regularly deep point discharge: every use (more than a month Or thirty times cycle) ;

1。 Nickel cadmium battery memory effect. Nickel cadmium battery use in the process of operation, if the battery didn't get it finished all start charging, second point discharge, can not release all the power. Nickel cadmium battery, for example, after a release only eight hundred percent of the electricity charge, after fully charged, the battery can only release the eight hundred percent of the battery, this kind of situation is called memory effect.

2。 Nickel cadmium battery have on the surrounding environment pollution, very is highly toxic, cadmium have harm to the person is very big.

3。 Nickel cadmium battery does not support the high and low temperature quick charge.

2, nickel metal hydride rechargeable batteries

consistent size ni-mh rechargeable battery is higher than the nickel cadmium battery is about one point five ~ 2 times, and no cadmium pollution, now already generally is widely used in intelligent communication, and so on a variety of large and medium-sized industrial dell laptop computer a hand-held electronic devices. Larger capacity of nickel metal hydride rechargeable batteries is already widely used in gasoline/electric hybrid vehicles

1. Nickel metal hydride rechargeable batteries don't include poisonous substances, main ingredients for nickel, rare earth, high value of recycling use ( There are residual value) , recycling the difficulty coefficient is small, the basic can be recycled to make full use of all, green development.

2。 Nickel metal hydride rechargeable batteries are hydrogen ions and the metal nickel composite power reserves more than three hundred percent of the nickel cadmium battery, on the market under the capacity of other than the nickel cadmium battery is lighter.

3。 In terms of point discharge rate, the tip of the nickel metal hydride rechargeable batteries discharge ratio is far beyond the nickel cadmium battery;

4。 And down in life, the same conditions, nickel metal hydride rechargeable battery is higher than the nickel cadmium battery;

5。 Nickel metal hydride rechargeable batteries compatible with high and low temperature quick charge;

6。 Than the nickel cadmium battery poor adaptability, less than 10 ℃, can not quick charge; Less than 0 ℃, can not slow filling.

7。 The hydrogen storage capacity of hydrogen storage alloys is very strong. Per unit volume of hydrogen storage density, is the same temperature, working pressure of gaseous hydrogen under standard one thousand times, which is equivalent to high pressure hydrogen storage one thousand atmospheres. But nimh rechargeable battery cycle life is greatly less than the nickel cadmium battery

8. Nickel metal hydride rechargeable batteries have no memory effect. Therefore do not need to concern use problem like nickel cadmium battery. Removal of large quantities of used in electronic products, is the earliest time of the Toyota Prius hybrid adopted by

special remind message:

if you want to the nickel metal hydride rechargeable battery recharged, intentional to point discharge that is not necessary, you do only shorten the service life of nickel metal hydride rechargeable batteries, is dangerous.

you using only a battery resistance connect the battery to point discharge is not desirable, have no way to control work current, easy to put on ov, even can cause series battery positive and negative poles of the pack

nickel metal hydride rechargeable batteries and nickel-cadmium batteries similarities

nimh battery and nickel cadmium battery, also belongs to alkaline batteries, its characteristics and nickel cadmium battery, nimh battery does not include cadmium, copper, however, there will be no industrial pollution problems.
