Battery energy density is improving at about 7% per year. (http://www.greencarreports.com/news/1074183_how-much-and-how...). After 10 years, that's a 97% improvement. If one of the new battery technologies becomes feasible with all of the new investment in battery research, there could be a much bigger jump in energy density before then.

That's not really what the attached article says. That article says that (1) nobody has any reliable data; (2) the general trend is assumed to be down; (3) the order of magnitude of the current data variance is 10x the "guestimate" of the future growth rate. Not sure this is the type of data you want to extrapolate from.
