SK Energy and USABC to Evaluate SK Li-ion Batteries for Electric Vehicles

SK Energy will participate in a one-year technology assessment program of its batteries for electric vehicles with the US Advanced Battery Consortium (USABC). USABC will provide 50% of the funding for the project, according to SK.

SK Energy, Asia’s fourth largest energy provider and Korea’s first oil refining company, develops and manufactures lithium-ion battery separators (LIBS) as well as lithium-ion batteries for applications ranging from consumer electronics to transportation. The company is the main battery supplier for the Mitsubishi Fuso hybrid electric trucks (earlier post), as well as the supplier for Korea-based CT&T’s low-speed electric vehicles. It also is the supplier for Korean government’s EV project with Hyundai Motors.

SK Energy uses a lithium manganese oxide cathode material, mixing in NMC material for stabilization; a surface-modified graphite on the anode; a gel polymer electrolyte; and a ceramic-coated proprietary SK separator featuring low shrinkage and high heat resistance. SK cells have a specific energy density of around 140 Wh/kg. (Earlier post.)

SK Mobile Energy, the battery division of SK Energy, is currently marketing four large format lithium-ion cells for electric vehicles: the H65 for hybrids, and the P135, P155, and P200 for plug-in hybrid electric vehicles.

The United States Advanced Battery Consortium (USABC), an organization whose members are Chrysler, Ford and GM, was formed in 1991 to sponsor development of advanced high-performance batteries for Electric Vehicle (EV) applications in the US. USABC has carried out a number of battery development programs, focusing on low-cost and long-life batteries with varying power-to-energy ratios.
