"Enertech is one of the largest lithium-ion battery producers in Korea, behind only LG Chemical and Samsung," said Ener1 CEO Charles Gassenheimer. "This acquisition gives us immediate scale and volume manufacturing ability, as well as an important beachhead for supplying Asian car makers that plan to use lithium-ion technology in their electric drive vehicles."
Enertech is one of just a handful of companies that specializes in producing large format flat (or "prismatic") cells, which Ener1 believes offer significant performance and manufacturing advantages over more common cylindrical designs. The company operates a 200,000-square-foot, state-of-the-art plant outside Seoul capable of producing cells for 15,000 electric vehicle battery packs per year. Enertech has also worked with EnerDel to supply cells for prototype and preproduction systems for Think Global.
