Extracting the various mineral components of a battery has proven difficult and costly in the past, and new research focuses on ways to reuse cathodes and other battery parts, according to Argonne researchers. Lead acid batteries were once rarely recycled, but now nearly all are broken down for reuse in internal combustion engines. The administration's options to spur domestic recycling include direct investment in projects and scientific research, as well as spending funds approved by Congress. Washingtons recycling focus comes as other regions are doing the same.
