Chinese bid for A123 may raise security risks: Senators

WASHINGTON (Reuters) – A Chinese company’s attempt to take over government-backed battery maker A123 raises serious national security concerns, a bipartisan group of lawmakers said this week, adding to growing congressional opposition to the deal.

China’s Wanxiang Group Corp is currently competing with U.S.-based Johnson Controls Inc to buy bankrupt A123, which makes lithium ion batteries for electric cars.

The government must ensure that any sale of A123’s technology, which has also been used by the military and to support the U.S. electrical grid, does not threaten domestic security, the senators said in letter to Treasury Secretary Timothy Geithner, Energy Secretary Steven Chu and other top cabinet officials.
