This should come as no real surprise, but is very welcome all the same. One senior executive with a global lithium battery manufacturer recently shared with me his opinion that energy density would improve at least 30% annually for some years to come.  This level of improvement is game-changign, not just for cost reductions, but also for the ability to expand range in electric vehicles, and duration for stationary energy storage.

Developments in the sector coming at an astonishing rate, yet we are held up by policy decisions and governments whose understanding of the sector is minimal, and whose speed of change is glacial (do we still have glaciers?).
