NiMH batteries are a good performance battery. NiMH battery is divided into high pressure nickel hydrogen battery and low pressure nickel hydrogen battery. The nickel-hydrogen battery positive electrode active material is Ni (OH) 2 (called NiO electrode), the negative electrode active material is a metal hydride, also known as the hydrogen storage alloy (electrode is referred to as hydrogen hydrogen hydrogenide), and the electrolyte is 6 mol / L hydroxide solution.

Nickel-hydrogen batteries are more and more attention to a tight direction for hydrogen energy. The emergence of nickel-hydrogen batteries is the improvement of environmental awareness and the inevitable result of the development of electronic information industry, and its development and progress is inseparable from the development and use of aerospace high-pressure nickel-hydrogen batteries. Nickel-hydrogen batteries have extremely complex constituent structures, detailed positive and negative plates, separators, sealing spacers, insulating cover, metal housing, plastic sleeve, electrolyte, negative tub, and positive cap, etc.

NiMH batteries are subject to retail market, cordless telephone, cordless vacuum cleaner, personal care products, lighting, electric tools and electric vehicles. Nickel-hydrogen batteries should be kept in use: 1. Use the process to avoid overcharge.

Within the life life, use the process to avoid overcharge, because the overcharge is easy to make positive, negative electrode expansion, resulting in the loss of reactive products and diaphragm damage, conductive network damage and battery ohm polarization. 2. Alete electrolyte deterioration.

In the life-aspigenous life of the nickel-hydrogen battery, electrohydride should be suppressed. 3. Storage of nickel-hydrogen batteries.

Saving the nickel-hydrogen battery should be sufficiently charged, if the battery is stored for a long time in the battery, the function of the battery negative hydrogen storage alloy will be reduced, and the battery life is reduced.
