Ener1 Indiana-based subsidiary Enerdel manufactures of commercial-scale automotive-grade lithium-ion battery systems.
Shares of lithium-ion battery technology company Ener1, Inc. (NASDAQ: HEV) (market cap $292 million) had plunged more than 27% by mid-day after the company reported at the market close Tuesday that it increased Q1 2011 revenues but suffered major net losses largely attributed to the write-down of the company’s 48% investment in Think Holdings, AS, a Norwegian electric vehicle manufacturer.
