Tesla expects that the production capacity of 4680 batteries will reach about 100GWh by the end of 2022. Panasonic and LG New Energy have also successively invested in the construction of production lines, and production capacity is expected to be gradually released around 2023.
Compared with the 4680 battery, the "Kirin battery" is a square battery and adopts a module-less design. Hundreds or thousands of cells are directly arranged in the box, eliminating the need to assemble multiple cells into a Module link. Compared with the previous battery pack model, the CTP solution can increase the space utilization of the battery pack by 15% to 20%, reduce the number of battery pack components by 40%, increase production efficiency by 50%, and also effectively reduce battery costs.
At the same time, this Kirin battery uses large-area cooling technology for battery cells. Based on the changes in the battery cells, the water cooling function is placed between the battery cells, quadrupling the heat exchange area. Therefore, the battery temperature control time is shortened to half of the original time, and it supports 5 minutes of fast hot start and 10 minutes of fast charging.
Some people believe that Kirin batteries have higher energy density and cruising range than 4680 batteries, which will be a major breakthrough for the new energy vehicle track. Battery life and safety have always been the key to restricting the popularity of electric vehicles. Once major breakthroughs are achieved, the penetration of new energy vehicles will continue to increase.
