Know the advantages and disadvantages of nickel-metal hydride batteries in one article

The lithium battery manufacturing industry in mainland my country is a period of rapid development, especially in the capacity of high-power nickel-metal hydride batteries and nickel metal hydride batteries. There are many manufacturers from social groups of corporate customers, but nickel-metal hydride battery manufacturers are large companies in my country. Very few, many small private companies. Now our country has a little famous battery capacity in Shenzhen, so today the author will take you to know the advantages and disadvantages of Ni-MH batteries. Ni-MH battery manufacturer Ni-MH battery itself has a relatively stable atomic mass, a five-toxic, harmless, healthy and green battery. Nickel metal hydride battery generates hydroxyl ions and nickel, constant voltage discharge, fast charging, charging indicator body, support and mixing filling, support for new and old batteries, reverse polarity creep, reserve more than 300% nickel Cadmium batteries have lighter battery capacity than nickel-cadmium batteries, have a long service life, and have no pollution to the natural environment at the same time. The disadvantage is that nickel-metal hydride batteries are much more expensive than nickel-cadmium batteries, and the overall performance of lithium batteries is worse. Nickel metal hydride batteries use constant current charging. According to the battery's acceptance of current, different currents can be used to charge the battery. Do not limit the battery voltage when charging. The design of nickel-metal hydride batteries is derived from nickel-cadmium batteries, but it has made great breakthroughs in improving the memory effect of nickel-cadmium batteries. The key transformation is to replace the cadmium in the negative electrode with hydrogen storage aluminum alloy, so the metal hydride nickel battery is a common example of material innovation. Operating temperature range: charging: 0~45℃, discharging: -10~60℃, storage temperature range: storage (1 year) -20℃ to +25℃, storage (6 months) -20℃ to +35℃, storage (3 months) Advantages of -20℃ to +45℃ nickel-metal hydride batteries: 1. High energy density, 1.5 times that of nickel-cadmium; 2. The battery voltage is 1.2v-1.3v, which is similar to the voltage of nickel-cadmium batteries; 3 . No memory effect, long cycle life; 4. Can amplify current, strong resistance to overcharge and over discharge; 5. No pollution, healthy and environmentally friendly battery. Nickel-hydrogen battery defects (defects) 1. The price is higher than that of nickel-cadmium batteries, and the cathode material is rare-earth metal alloy materials; 2. High self-discharge speed.
