CATL Unveils One Shell, Two Cells Battery Architecture to Standardize EV Pack Design

CATL One Shell Two Cells structural design standardizes lithium and sodium ion battery enclosures to improve electric vehicle production and grid storage durability

Chinese battery producer CATL announced it has developed a structural design for standardized energy storage enclosures that accommodates various chemistries. The system, called One Shell, Two Cells , allows for either lithium ion or sodium ion cells to be enclosed in the same standardized casing, without any adjustments to the thermal management or chassis structure. CATL stated that this design will ease the development and production of electric vehicles, grid stationary storage, and automated battery swapping infrastructure.
