The advantages and disadvantages of lithium manganate and ternary materials can be complementary

The ternary material can be used as a positive electrode material in the field of automobile power battery.At present, Chinese lithium ion battery enterprises generally take the route of large square battery in the field of automobile power battery, so they need to solve the safety problem of battery like LEJ. Meanwhile, the cost is much lower than LEJ, which is difficult to achieve.It’s also hard to follow tesla’s path of small, cylindrical batteries by working on battery module technology, which is a common weakness of Chinese companies.From all aspects of the comprehensive view, moke believes that the ternyuan material to become the mainstream of China’s electric vehicle lithium ion battery cathode material, very difficult to achieve in the short term.

Under the actual situation that most battery enterprises take the route of large square or polymer batteries, the ideal positive electrode material in the future two or three years is the combination of “lithium manganate + ternary material”, mainly lithium manganate.Ternary materials can make up for the low energy density of lithium manganate, while lithium manganate can make up for the defects of simple ternary materials in acupuncture and overcharging, which are just complementary.The lithium manganate material here is generally modified lithium manganate.

In farther down three to five years, “lithium manganese acid + ternary material” automotive power battery is combination will still be a priority of the anode materials selection, the difference is two kinds of materials will be further modified, the purpose is to continue to improve material performance, including modified manganese acid lithium materials will development in the direction of the high voltage, and modified the ternary material will develop in the direction of the high capacity.The former lithium nickelmanganate will be the main direction of development, while the latter although the high capacity of NCM is one direction (such as NCM 811), NCA may become a more important direction of development.
