Introduction of application of nickel-metal hydride battery

The development of nickel-metal hydride battery application field and the development of nickel-metal hydride battery technology and the change of nickel-metal hydride battery market capacity go hand in hand.

Nickel-metal hydride batteries were the first to enter industrialization in countries such as Japan. The use of nickel-metal hydride batteries was mainly to replace nickel-cadmium batteries in the field of notebook computers and mobile phones. However, since the commercialization of lithium ion batteries in the 1990s, it has been more than 10 years since then. Lithium-ion batteries have replaced nickel-metal hydride batteries to occupy the portable electronic equipment market; In the field of communications, nickel-metal hydride batteries have also been forced to withdraw.

However, the current price of nickel-metal hydride batteries is lower than that of lithium-ion batteries, and the safety performance is also superior to that of lithium batteries. As a result, some notebook computers began to reuse nickel-metal hydride batteries. Because of these two advantages, nickel-metal hydride batteries have also begun to return in areas such as electric tools, digital cameras, electric vehicles, and uninterrupted mobile power supplies for mobile phone relay bases.

In terms of applicability, nickel-metal hydride cells have superior low temperature performance and are also suitable for high current discharge. Therefore, nickel-metal hydrogen batteries are often assembled to meet the needs of portable electronic equipment. Applications in this area cover almost all walks of life. Such as: portable printers, mobile tools, digital products; Medical equipment, remote communication equipment, LCD TV; Communication instruments, laser instruments, instrumentation and electric toys.

The comprehensive characteristics of nickel-metal hydride batteries such as high energy density, high power, and no pollution also make them suitable for use as power batteries. Some nickel-metal hydride battery plants have developed nickel-metal hydride battery applications for power vehicles, electric motorcycles, and electric bicycles. This feature has also been extended to the military field and applied to communications backup power sources, space technology, robots andspecials.

In 2006, China produced 1.3 billion nickel-metal hydride batteries, surpassing Japan as the largest producer, because China has 70 % of the world's rare earth reserves, and rare earth is the main raw material for nickel-metal hydride battery negative hydrogen storage alloys. Among the applications mentioned above, the use of nickel-metal hydride cells is reflected in the main direction of the Chinese market is mobile communications, laptops, electric tools and automotive batteries.
