I actually expect higher adoption to drive improvements in charging technology. Of the top of my head a naive way to make batteries charge faster is that that they could make the individual cells as smallest as possible therefore reducing the amount of time that individual cells need to charge[1]. The batteries would be made up of thousands of these cells that could then be charged in parallel. If they can make it so that each cell can get charged in only a couple of minutes then one of the major hurdles of electric cars will be gone. [1] I'm assuming that the smaller the cell the faster that it can be charged. Anybody knows if this is true?
