LG Energy Solution recently canceled development of prismatic batteries, TheElec has learned.

Earlier this year, the company began reviewing the product to see if it would be viable, but recently concluded it was not commercially feasible.

Prismatic batteries put materials in boxes and are actually an alternative version to cylindrical batteries.

Samsung SDI and Chinese battery makers like CATL and BYD make the type.

Northvolt Toshiba, Morrow Batteries, Verkor, Britishvolt and Automotive Cell Company also manufacture prismatic batteries.

Meanwhile, LG Energy Solution focuses on manufacturing pocket batteries. It also manufactures cylindrical batteries, but the majority of its batteries for electric vehicles and energy storage systems are pocket batteries.

It began developing prismatic batteries to potentially add variety to its portfolio while absorbing the benefits of technology.

Sources said the company concluded there was no benefit in sourcing components and equipment to make prismatic batteries more practical than other types.

LG Energy Solution was able to focus on increasing its production capacity, they added, so the ease of capacity expansion for a certain type of battery was more important than the technology.

Pocket batteries use pocket films instead of cans to hold the materials. This makes it easier for manufacturers to increase energy density, but they also need to remove the gas that forms inside during production.

LG Energy Solution is focused on improving its manufacturing process, adapting new ways of stacking battery materials, such as advanced Z-stacking.

The method prevents separators from falling by adding more lamination rolls during production.
