2018-10-01: Governments from California to China and South Korea -- even Donald Trump's Washington -- have taken steps that will make battery power more ubiquitous. There's just one hitch to this battery boom: The world isn't making nearly enough. All of the new demand from North America, Europe and Asia is constrained at the moment by a market that remains heavily dependent on a few producers. Data on the global supply of batteries is hard to come by, but close observers of the industry have noticed evidence of the shortfall. "We've never seen such demand," said Yayoi Sekine, a New York-based analyst at Bloomberg NEF. "But the supply is struggling to keep up."
Oddly, however, lithium-ion battery-rack prices have continued their annual decline, even in the face of constrained supply and expectations of ever-growing demand. To get a clear sense of the near future, consider battery-powered cars: Today, there are more than 3 million electric vehicles on the road worldwide; by 2025, Volkswagen AG alone plans to build as many as 3 million electric vehicles per year. Those vehicle batteries -- in addition to storage batteries for homes, businesses and utilities -- will have to come from somewhere.
