Failure of A123 Systems becomes part of fray

Advanced battery maker A123 Systems Inc. filed for bankruptcy protection Tuesday after burning through more than $100 million in taxpayer money, thrusting the Waltham company into the middle of the presidential sparring over energy and economic policies.

Shortly after A123 filed in federal court in Delaware, the campaign of former Massachusetts governor Mitt Romney renewed its attacks on President Obama’s support, through federal grants and loans, of emerging clean energy companies. In the first presidential debate, Romney sharply criticized Obama for the failures of government-backed firms, including California solar panel maker Solyndra LLC, which defaulted on more than $500 million in federally guaranteed loans.
