lithium ion battery technology is dead, it just doesn't know it yet, as I detailed on an earlier thread.
Weight, power density and fast recharge times all have a cure with the up an coming graphene battery tech.
That said it will take some time for the new disruptive tech to prove its commercial and technical savvy, there is a lot of cash invested in the current lithium paradigm.
My self I think a good half step is good hybrid tech, not the Prius kind which really is rubbish! Have a look at what Honda is doing with their hybrid electric Accord, it really is an efficient and fantastic driving car, I have taken a few on extended test drives and really loved them.
Of course you could go full electric fairly cheaply today with likes of Nissan Leafs and the like or the i3 or the half and half Mitsubishi outlander.
Whatever way you think about it electric cars have already grabbed a significant foot hold and we can expect to see them dominating the market in the next 8 to 12 years....... I of course will still be driving my same P6B that I have since 1987!
