加拿大28精准大小算法   Summarizing the development route of China's and global automotive power batteries, roughly through such a vein: nickel-hydrogen--Lithium--fuel cells, and in the current state, China's mature technology is still powered by nickel-metal hydride batteries, because lithium ions There are still some technical difficulties in the battery that need to be overcome, and the hydrogen fuel cell is still in the laboratory stage. In other words, according to industry standards, the three are separated in three different technical stages: maturity, development, and start-up.

  After many discussions, the country has now shifted its development focus from lithium batteries to nickel-metal hydride batteries. The main reason is that nickel-metal hydride rechargeable batteries are more mature than lithium batteries, and mineral resources are more abundant, making new energy vehicles easier in the future. Enter the stage of commercialization. However, compared with lithium batteries, nickel-hydrogen batteries are currently the mainstream of commercialization, but the laboratory data of the main indicators are lower than lithium batteries, and there is basically no room for improvement in theory; although lithium batteries have superior performance, safety is still Can not be guaranteed, and relatively high cost also hinders its commercial use.
