In the cell-to-pack configuration, battery cells are assembled to build a pack without using modules, which reduces the need for inert materials and increases energy density. In cell-to-chassis concepts, battery cells are used as part of the EV structure without being assembled into a battery pack beforehand.
In terms of energy density, the average energy density of traditional battery packs is 140-150Wh/kg, and the energy density of CTP battery packs can reach more than 200Wh/kg. In March, Wu Kai, chief scientist of CATL, said that the third-generation CTP technology is ready for mass production and is expected to be officially launched in April this year.
