About the nickel metal hydride batteries ( NIMH) The application of anode materials

Source: 2020 - 04 - 11 18:51 hits: nickel metal hydride ( NIMH) The application of anode material nickel metal hydride battery voltage is 1. 2 v, this is put forward in the 1970 s. A lot of research is concentrated in the 1980 s, industrial production began in the early 90 s. Nickel metal hydride batteries were originally as a substitute for nickel cadmium battery. Nimh battery capacity more than 30% of nimh batteries, more light than nimh batteries, long service life, can be in a certain extent, reduce the 'memory effect' of nimh batteries, nimh batteries get more extensive application. Its scope includes the following several aspects. Portable electronic equipment power supply: since the commercialization of lithium-ion batteries in the 1990 s, in the next ten years, replaced the nimh batteries, lithium-ion batteries in portable electronic devices markets. In the field of communication basic exit also forced the nimh batteries. But lower than the price of the nimh batteries, lithium-ion batteries, and safety performance is better than that of lithium battery. As a result, some laptops and start using nimh batteries, due to the two advantages, nickel metal hydride batteries in electric tool, electric cars, mobile phones, digital cameras, and mobile power in areas such as part of the return. In terms of applicability, nickel metal hydride battery has good low temperature performance, can also be applied to large current discharge, so the nimh batteries are often assemble nimh battery pack, in order to meet the needs of the portable electronic devices. The application of almost involved in all walks of life. Such as: portable printers, mobile tools, digital products; Medical equipment, telecommunications equipment, LCD TV; Communication instrument, laser instrument, instrument, electric toys, etc. Power battery, nickel metal hydride batteries with comprehensive properties such as high energy density, high power, no pollution, is suitable for use as power battery. Some nickel metal hydride battery factory has developed the use of nickel metal hydride battery powered cars, electric motorcycle and electric bicycle. This function also expands to military applications, such as communication standby power, space technology, robots and submarines. In our country, the nimh batteries got rapid development. In 2006, China produced 1. 3 billion nimh batteries, surpass Japan as the largest producer. This is because China has 70% of the world's rare earth reserves, which is the main raw material of nickel metal hydride battery cathode hydrogen storage alloy. In these applications, nickel metal hydride batteries in the Chinese market is the main direction of the mobile communications, laptop computers, power tools and automotive batteries.
