Will quaternary lithium battery technology be the future development direction of power NiMH No.7 battery?

Will quaternary lithium-ion battery technology be the future development direction of power NiMH No.7 battery? Under the current new energy industry, the power lithium battery industry is developing rapidly. Faced with a huge market gap, upstream manufacturers are also rising. The cobalt-free materials and quaternary material batteries of the stacking era are the "vanguard" of the development of power NiMH No.7 battery, and officially launched the cobalt-free materials and quaternary material batteries developed and produced by them, opening a new chapter in the development of the power lithium battery industry.

Will quaternary lithium-ion battery technology be the future development direction of power NiMH No.7 battery?

The stacking era is also known as the 3.0 era in the field of power NiMH No.7 battery. It refers to the era characterized by stacking technology on the road of innovation of new energy power NiMH No.7 battery, and new processes, new standards, new materials, and new technologies have emerged in large numbers and are specially born for automobiles. The birth of cobalt-free materials and quaternary material lithium-ion batteries can be said to be born at the right time.

Cobalt-free materials greatly solve the problem of raw materials while extending battery life, which helps to reduce costs and reduce dependence on foreign countries. Quaternary materials are more resistant to high temperatures and have better safety performance. The advent of these two materials has added new vitality to the power lithium battery market and has also become a strong competitor.

The most troublesome thing about ternary lithium-ion batteries is that they can supply oxygen without the assistance of external conditions. The advantage of quaternary lithium-ion batteries is that they can reduce gas production by 25%, and their own heat resistance is also better, so the probability of combustion is small. From the progress point of view, the quaternary material battery cell project was established in September 2018, and the material development will be completed by the end of 2019. It is expected to achieve material SOP in December 2020 and battery cell SOP based on quaternary materials in November 2022.

Due to the eager desire of the power lithium battery industry for endurance, but higher energy density is also accompanied by more active chemical properties, safety performance is an issue that the entire industry must face up to. Against this background, the quaternary cathode material was launched, and the world's first quaternary material battery cell was announced based on this material.

The quaternary lithium-ion battery developed by GM and LG is likely to set off a round of industrial changes in power NiMH No.7 battery. Compared with NCM/NCA ternary lithium-ion battery products, quaternary lithium-ion batteries have the advantages of longer cycle life, excellent safety, lower cost, better heat resistance, and less gas production. For car companies and battery manufacturers, these advantages mean that quaternary lithium-ion batteries are an option that is hard to refuse.

The stable physical and chemical structure of quaternary lithium-ion batteries can support the future high-nickel route of power NiMH No.7 battery. At the same time, the mixing of relatively cheap aluminum elements greatly reduces the content of expensive cobalt elements in the positive electrode of power NiMH No.7 battery, which is also very effective in reducing the cost of power NiMH No.7 battery. Whether it is a technical route or a market level, the future prospects of quaternary lithium-ion batteries are very broad. It can be said that quaternary lithium-ion batteries are the most revolutionary battery technology before the birth of all-solid-state batteries.

Regarding the development of new materials and technologies for power NiMH No.7 battery in the future, there are two evaluation dimensions for new materials and technologies for power NiMH No.7 battery from the perspective of industrialization. The first is the technical maturity. Products with good technical direction and technical maturity have industrial promotion value. The second is the application value. We have nearly 10 years of application experience in motorcycles and electric tools, and will apply them to new energy vehicles after maturity. The development of any technology must be gradual and down-to-earth.
