1, unit volume battery energy density increased, more than 1\/3 than the traditional battery.
2, the material cost is reduced by about 1\/4, which includes materials and human resources.
3, the battery size is small, can bring better space performance for the vehicle.
4, the battery is light in weight, the energy consumed to overcome its own resistance is reduced, and the battery life is further increased.
5, better safety performance. In the case of high temperature, overcharge, extrusion, acupuncture, etc., the probability of fire and explosion of the battery cell is reduced.
Disadvantages of Yadi blade battery
1, low temperature charge and discharge performance is poor. This is the \"occupational disease\" of lithium iron phosphate, and the battery power will be greatly discounted in cold conditions in winter. The low temperature limit of lithium iron phosphate is -20 ° C, while the ternary lithium battery can reach -30 ° C. Ternary lithium attenuates about 10% at low temperature, and lithium iron phosphate reaches 20%.
2, the battery is difficult to repair after collision. Because the blade battery eliminates the structure of the support cell, each cell itself is used as a support. Under the impact of external force, it is difficult to ensure the integrity of the battery cell. If one cell is damaged, the rest of the cells in series will also be affected
