The new rare-earth magnesium-nickel-based hydrogen storage alloy electrode production line invested by China Rare Earth Alloy Materials Technology Group has started normal operation.
Rare earth magnesium-nickel-based hydrogen storage alloy electrode materials have the advantages of high capacity and low self-discharge, and are considered to replace the traditional AB5 type rare earth-based hydrogen storage alloy. The nickel-metal hydride battery produced by this new electrode product has excellent low-temperature stability. A large number of experiments have shown that the nickel-metal hydride battery produced by the new material can make the car's performance very stable, even in the extremely cold environment of the north. use. Ni-MH battery is currently used by Toyota and other mainstream car companies in hybrid vehicles. In supporting the development of the new energy vehicle industry, China also regards nickel-hydrogen power batteries as a key support object.
"Based on the alloy manufacturing technology of the Institute of Alloy Materials, through the matching relationship between the phase structure of the rare earth magnesium nickel-based hydrogen storage alloy and the electrochemical hydrogen storage performance, the alloy structural characteristics are optimized, and rare earth magnesium nickel-based hydrogen storage alloys with different advantageous properties have been developed. New products. "Xiao Ming, the person in charge of technology research and development, said.
It is reported that this production line is the first new rare earth hydrogen storage alloy production line with independent intellectual property rights in China. The battery capacity of this product as an electrode is more than 30% higher than that of traditional nickel-metal hydride batteries and hydrogen storage alloys.
The nickel-hydrogen battery prepared by the new rare-earth magnesium-nickel-based hydrogen storage alloy electrode is more environmentally friendly than the nickel-cadmium battery and safer than the lithium battery. It can be widely used in hybrid batteries for automobiles and solid-state hydrogen storage and hydrogen fuel cells.
