MIT News – The reasons behind lithium-ion batteries’ rapid cost decline
A new study finds that investments in R&D on materials and chemistry were key, while economies of scale contributed somewhat less.
Some of the researchers behind that earlier study have now analyzed what accounted for the extraordinary savings. They found that by far the biggest factor was work on research and development, particularly in chemistry and materials science. This outweighed the gains achieved through economies of scale, though that turned out to be the second-largest category of reductions.
