The full name of ternary lithium battery is “ternary material battery”, generally refers to the lithium battery using lithium nickel cobalt manganese oxide (Li (NiCoMn) O2, NCM) or lithium nickel cobalt aluminate (NCA) ternary cathode material. Salt, cobalt salt, and manganese salt are adjusted differently as three different component ratios, so they are called “ternary”. The ternary lithium battery includes many types of batteries with different ratios. It has many advantages such as small size, high density, high temperature resistance and good cycle performance, and it is widely used.
The blade battery is based on lithium iron phosphate battery technology. The battery cell is reasonably elongated under a certain volume, and it has the advantages of increasing the battery energy density and increasing the heat dissipation area of the battery cell. Because the battery is more “flat” and “long” than the traditional square battery Bar” shape. The length of the blade battery can reach up to 2500mm, which is more than 10 times that of the traditional ordinary lithium iron phosphate battery, which greatly improves the efficiency of the battery cell group, and can adjust the size based on different needs.
The biggest advantage of lithium iron phosphate is safety and stability, high cycle life, the disadvantage is poor low temperature performance, relatively low energy density, while the ternary lithium battery can achieve relatively high energy density, but poor high temperature performance, safety and stability Compared to lithium iron phosphate, it is also slightly inferior. Although the blade battery is also a kind of lithium iron phosphate battery, its CTP technology (directly integrated as a battery pack) has greatly improved the overall integration efficiency, the flat design of the battery cell, and the recombination of the battery sequence The optimization has greatly improved the overall space utilization and energy density of the power battery pack, which will have a new impact on the existing power battery industry.
