Application of anode materials for nickel-hydrogen battery (NIMH)

Application of Nickel Metal Hydride (NIMH) Anode Materials The voltage of nickel-metal hydride batteries is 1.2v, which was proposed in the 1970s. A lot of research is concentrated in the 1980s, and industrial processing began in the early 1990s. Ni-MH batteries were originally used as a substitute for Ni-Cd batteries. The battery capacity of Ni-MH batteries is 30% more than that of Ni-MH batteries, lighter than Ni-MH batteries, and has a longer service life. It can reduce the memory effect of Ni-MH batteries to a certain extent and make Ni-MH batteries more widely used. Its scope of application includes the following aspects. Power supply for portable electronic devices: Since the commercialization of lithium batteries in the 1990s, in the next ten years, lithium batteries have replaced Ni-MH batteries and occupied the portable electronic device market. In the field of communications, nickel-metal hydride batteries are also forced out of the game. However, the current price of nickel-hydrogen batteries is lower than that of lithium batteries, and the safety performance is better than that of lithium batteries. Therefore, some notebook computers have begun to use nickel-metal hydride batteries. Due to these two advantages, nickel-metal hydride batteries have also partially returned to the fields of electric tools, digital cameras, electric vehicles, mobile phones and mobile power supplies. In terms of applicability, nickel-hydrogen batteries have good low-temperature performance and are also suitable for high-current discharge. Therefore, nickel-hydrogen batteries are often assembled into nickel-hydrogen battery packs to meet the requirements of portable electronic devices. Applications in this area involve almost all walks of life. Such as: portable printers, mobile tools, digital products; medical equipment, telecommunications equipment, LCD TVs; communication equipment, laser equipment, instruments, electric toys, etc. Power lithium-ion battery: Ni-MH battery has the comprehensive characteristics of high energy density, high power, and pollution-free, so it is suitable for use as a power lithium-ion battery. Some nickel metal hydride battery factories have developed power cars, electric motorcycles and electric bicycles that use nickel metal hydride batteries. This function is also extended to military applications such as communications backup power, space technology, robotics and submarines. In our country, nickel-metal hydride batteries have developed rapidly. In 2006, my country processed 1.3 billion nickel-metal hydride batteries, surpassing Japan to become the largest processing country. This is because my country has 70% of the world's rare earth reserves, and rare earths are an important raw material for nickel-hydrogen battery anode hydrogen storage alloys. In the above-mentioned application fields, the important direction of nickel-metal hydride batteries in the Chinese market is mobile communications, notebook computers, power tools and automotive battery packs.
