South Korea’s battery maker SK On will go with pouch cells to venture into the lithium iron phosphate (LFP) battery market currently led by Chinese manufacturers that have made prismatic and cylindrical cells standards for LFP electric vehicle batteries.
The battery spinoff from SK Innovation has got closer to commercial production of a pouch-type LFP battery for electric vehicles with all development and design phases completed, according to internal sources on Thursday.
Progress has been remarkably fast in the company’s engineering sector while the nickel-cobalt-manganese (NCM) battery maker last month said it is in the phase of examining its advance into LFP batteries for low-cost standard range models that are increasingly drawing attention from global EV brands such as Tesla.
SK On is now looking through B sample prototyping to test the waters with global EV makers as early as next year. The B sample is the most complete as possible fresh out of a pilot plant or lab.
SK On is reportedly leveraging its technological capabilities built through its NCM battery development to boost range limits of LFP batteries. A pouch architecture is another advantage to range extension as the cell is lighter, thinner and design flexible as compared to common hard case cells.
The battery industry is focusing on lightweight and high energy density cell fabrication to help increase the driving range of EVs. SK On will gain an edge against established LFP competitors by applying its own...
