Well if it's the anode that was the problem then XG Sciences resolved that recently, see http://xgsciences.com/wp-content/uploads/2012/11/XG-Anode-Product-Sheet-Final.pdf Li-S looks promising as the high capacity replacement for standard Li-on.
XG sciences have stolen a march on this lot and have already stability tested their Li-S silicone/graphene anode battery over 400 cycles. Also, with Samsung on board I think they will soon have there high capacity battery in production quite soon.
It may be more practical to have EV batteries manufactured in stackable modular units each with 100 mile range capacity. This is ideal for most commuters and the most efficient weight to energy density ratio. The ability to add another battery module for extended range journeys would remove the need for frequent charging stops. This would be possible with the higher energy density of LiS Graphene batteries and XG Sciences appear to be a step ahead towards volume production. See http://www.prweb.com/releases/2015/03/prweb12575091.htm
Also recent work on the anode using a silicone/graphene mix holds a lot of promise (http://www.prweb.com/releases/2015/03/prweb12575091.htm)and may hit the market sooner than this Li-S variant. The next few years are going to be very interesting if these developments become an EV powertrain reality.
The use of silicone in the anode seems to stimulating a lot of research but the silicone/graphene mix as reported recently (http://www.prweb.com/releases/2015/03/prweb12575091.htm)looks the most promising for Li-S batteries thus far and will probably hit the market first. Come on guys, don't get jaded, the fun is just beginning.
H2 may be an option for lighter than air vehicles with the addition of this type of motor. A British company http://hybridairvehicles.com/ is about to launch a commercial vehicle that was originally developed for the US military (victim of cutbacks) and is hoped to carry payloads of 1000 tons. Think how many trucks that could take off the road. Solar panels on the top surface of this airship could help drive the motors if they went on to replace the existing diesels.
