Economist article on Battery Manufacturing, page-2

What I found most interesting was this paragraph:

"But getting prices down this way has not just produced cheaper, better batteries. It has also resulted in significant overcapacity. Cairn ERA estimates that last year the manufacturing capacity for lithium-ion batteries exceeded demand by about a third. Both it and BNEF say that the battery manufacturers are either losing money or making only wafer-thin profits on every electric-vehicle battery they produce. Despite the seeming glut, though, they all have plans to expand, in part to drive prices even lower. Mr Jaffe explains their thinking as that of the “traditional Asian conglomerate model”: sacrificing margins for market share. This may be a sound strategy given the ever-greater hopes for electric vehicles in the near future. But at the moment it is also one that looks rather unnerving. Although Mr Jaffe believes that increased demand for both electric vehicles and stationary storage will justify the rush to expand, he accepts that, for now, “It feels like a gold rush—but there’s no gold.”"
