Green Batteries’ Graphite Adds to China Pollution

As more environmentally conscious Americans do their bit to help clear the air by paying up for an eco-friendly Prius or a sporty Tesla, a damaging form of polluted rain is falling in China.
The link is graphite, a vital component in batteries used in Tesla’s Model S, Toyota’s plug-in Prius and other electric cars, as well as in electronic gadgets including iPhones. It’s mostly mined and processed in China where graphite pollution has fouled air and water, damaged crops and raised health concerns. Now, in response, Chinese authorities are closing dozens of graphite mines and processors in a bid for cleaner air even as global demand for the commodity is surging.
