HEV field lithium battery Nandi hydrogen battery

On the 8th, Luo Li, general manager of Keliyuan, said that China has the absolute patent advantage of hydrogen storage alloy powder, and in the field of hybrid electric vehicles (HEV) and high-power civil use, lithium batteries are difficult to replace nickel-metal hydride batteries, and the government should encourage the development of HEV. Efforts will be made to expand the application of rare earths in environmentally friendly vehicles.

In nickel-metal hydride batteries, the nickel content is 55%, the rare earth is 32.2%, and the others are cobalt, manganese and aluminum. 32.2% of the rare earth elements were 20.2% of yttrium, 8% of yttrium, 3% of yttrium, and 1% of yttrium. Luo Ji said that the rare earth used in nickel-metal hydride batteries is China's rich light rare earth, resource constraints are minor.

According to data provided by Luo Yu, the hybrid vehicles have significant environmental benefits. Compared with normal gasoline vehicles, HEV can save 30% to 50% of fuel and reduce emissions by 40% to 80%. If achieving 50% penetration, China It can reduce oil consumption from 7.5% to 12.5% ​​and reduce air pollution by 5% to 10%.

In terms of patents on hydrogen storage alloy powders, domestic enterprises have an absolute advantage. Luo Yu believes that “up to now, the patents for hydrogen storage alloy powders that have been authorized by Chinese-funded enterprises have been 116, accounting for 95.9% of the total number of authorizations. Acquired high-end application technologies and patents through acquisitions and localization, and together with the Xiamen Tungsten Industry achieved localization.”
