What is the technology of ternary lithium battery?
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.
