　　What is the technology of ternary lithium battery? Lithium-ion batteries are lithium-ion batteries that use lithium-ion cells or lithium-ion batteries. The ratio of lithium-ion batteries determines battery charging efficiency and reliability. Most ternary batteries currently on the market have relatively stable ratios and are therefore safer in terms of safety factors, but their main performance features seem limited.

　　Lithium-ion batteries have the characteristics of higher energy and higher operating voltage, so lithium-ion batteries with the same net weight have larger batteries, longer distances between vehicles, and faster speeds. However, its disadvantage lies in its weak stability and is useful if an internal short circuit fails or the battery's positive material encounters water, causing a fire. So usually the 18650 rechargeable battery has an aluminum shell for repair.

　　Lithium-ion battery manufacturers are working hard to prevent safety incidents due to the safety risks of lithium-ion raw materials. According to the characteristics of the ternary lithium material ternary lithium, manufacturers have a lot of time in multiple stages such as overcharge protection (OVP), overcharge protection (UVP), overtemperature protection (OTP) and overcurrent protection (OCP). .

　　At this stage, the pursuit of perfect high durability will not be easy to stop in the short term, which means that ternary lithium-ion batteries may still be many new energy sources in the long term. Moreover, the development trend in recent years can be seen that high-nickel ternary materials have become the goal pursued by many manufacturers due to their greater advantages in energy density. What is the technology of quaternary lithium battery? With the development and application of quaternary lithium-ion products, quaternary lithium-ion products have received widespread attention.

　　Quaternary, ternary or higher chemical elements, because of the chemical element cobalt, its price and cost in the market are very expensive. Many car companies are looking to a cheaper, more distinctive chemical alternative - a quaternion of lithium ions, achieved by removing or reducing cobalt. For example, by upgrading the three elements of high-component nickel, changing the basic practice of high-purity graphite negative level, and upgrading the silicon-carbon layer, a more stable quaternary lithium-ion battery is produced.

　　But these new batteries are not perfect at this stage and are still being explored. There are currently no cobalt rechargeable batteries other than quaternion lithium-ion batteries.

　　Cobalt reserves are already very low, with more than 60% of the world's cobalt in a guyana unstable state. The use of lithium-ion batteries (including special elements with unpaired electron spins) to reduce cobalt weakens the super-exchange state of electronic devices. As a new generation of lithium-ion battery technology, the safety factor of rechargeable batteries has also been improved.

　　Generally speaking, the technology of quaternary lithium-ion power supplies is not perfect enough, and there is still a long way to go before mass production can be completed. Quaternary AG13 battery can theoretically achieve high energy density, high reliability, and low cost.

　　However, the production process of NCMA battery cathode materials is much more complicated than that of NCM or NCA. Although the basic point of production is to control costs, in fact, in a short period of time, its product cost is undoubtedly higher than that of NCM or NCA because of the low Cobalt ncm811 raw material is higher than ncm622 raw material. Therefore, the market prospect of quaternary AG13 battery is unclear.

　　Summary: Technically speaking, quaternary AG13 battery may be safer than ternary AG13 battery, if it increases the technical limitations of mass production. However, the current technology of quaternary rechargeable batteries is not perfect enough, and there is still a long way to go before mass production can be completed. Therefore, ternary AG13 battery may be the key choice for today's automobile companies.
