DALIAN, China -- China Molybdenum, the world's second-leading producer of cobalt, plans to roughly double its output to meet growing demand for the key battery material, with an eye on outstripping industry leader Swiss rival Glencore.
But China's voracious appetite for the metal has raised the alarm in the U.S. and other countries. Labor rights concerns involving its mines in the Democratic Republic of Congo could also hamper the company's ambitions.
