The number one battery for pure electric vehicles is the ternary lithium battery.
Ternary lithium polymer battery refers to a lithium battery that uses nickel cobalt lithium manganate ternary cathode material as the cathode material. It is a precursor product to a ternary composite cathode material, using nickel salt and cobalt. Salt and manganese salt are used as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. It offers high security but low voltage.
Mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. At present, ternary material batteries have largely replaced lithium cobalt oxide batteries previously widely used in computersportable. used in the field of batteries. With the continuous improvement of the formula and the improvement of the structure, the rated voltage of the battery has reached 3.7V and the capacity has reached or exceeded the level of lithium cobalt oxide batteries.
Battery Characteristics
The full name of ternary lithium battery is “ternary lithium polymer battery”. The so-called "ternary lithium battery" is simply a ternary lithium battery. battery The cathode material is a type of lithium battery composed of three metal elements and lithium, such as lithium nickel cobalt manganate batteries which are currently widely used. The latest generation of ternary lithium batteries represented by this battery presents a qualitative improvement over other forms of lithium batteries, both in terms of battery cycle time and, more importantly, quantityof energy stored per kilogram.
Ternary lithium batteries can come in many forms. In addition to cylindrical batteries with metal shells such as 18650, there are also soft packaging shapes with aluminum plastic shells and square battery types. Among them, soft-shell batteries packaged in aluminum-plastic packaging are currently the most flexible form of lithium battery. Their size and thickness can be freely customized and they can be stacked in multiple pieces, giving them considerable application flexibility.
