With the R&D and application of honeycomb new energy quaternary lithium-ion battery, it has also attracted attention. So what is the technology of quaternary lithium-ion battery? Please see the analysis below.

Four yuan is more metal element than three yuan. Because cobalt is a metal element, its price and cost in the market are very high. Many car companies hope to find a metal element with lower cost and better performance to replace it. This four element lithium ion battery is an exploration that leaves out or reduces cobalt. For example, aluminum is added to the ternary base with high nickel content, and the conventional practice of graphite anode is changed to add silicon carbon layer, which forms a more stable quaternary lithium ion battery.

However, at present, this battery technology is not very mature and is still under exploration. In addition to the four element lithium ion battery, there are cobalt free batteries on the market. The cobalt reserves are small, and more than 60% of the world's cobalt is in the unstable country Congo in Africa. Reduce the cobalt element, adopt cobalt free electric core, doping specific elements with unpaired electron spins, and reduce the electron super exchange phenomenon.

NCMA material for quaternary lithium-ion battery has obvious advantages over NCM material in cycle performance and thermal stability. As a new generation of lithium-ion battery technology, the battery has been improved with high capacity cathode material, and the battery safety has also been greatly improved. To sum up, the technology of quaternary lithium-ion battery is not yet mature, and it still has a long way to go to achieve mass production.
