The last time I read about this, it was expected that, at one point, in 2020 or so, electrical vehicle batteries are finally going to become a relatively important component of the battery market. There's a lot of money being poured into it because a lot of people are trying to move towards electric vehicles, but in terms of actual numbers being produced, the EVBs are dwarfed even by regular car batteries. Of course, EVBs are incredibly important, especially from an R&D perspective, but I don't think the market is being driven my them. My information may be a little out of date though.

As for consumer electronics, it's worth remembering that there are probably thousands of coin-cell operated keychains for every smartphone whose energy density capacity is not being satisfied by our current technology. There are a lot of consumer electronic devices for which current battery technology is OK -- better density would be an improvement, as it is everywhere, but it's no longer the hog it is for smartphones. For those, ease of recycling, lack of fire hazard and the slightly simpler circuitry really are important.
