Parent of Obama-backed battery maker goes bankrupt

WASHINGTON – The parent company of an electric car battery maker that received a $118 million grant from the Obama administration filed for Chapter 11 bankruptcy protection on Thursday.

New York-based Ener1 said it has been affected by competition from China and other countries.

Ener1 subsidiary EnerDel received a $118 million stimulus grant from the Energy Department in 2009, and Vice President Joe Biden visited the company's new battery plant in Indiana last year.
