I see we've one or two Luddites on the forum.
What the future may hold:-
Solid state lithium-ion
Solid state batteries traditionally offer stability but at the cost of electrolyte transmissions. A paper published by Toyota scientists writes about their tests of a solid state battery which uses sulfide superionic conductors. All this means a superior battery.
The result is a battery that can operate at super capacitor levels to completely charge or discharge in just seven minutes - making it ideal for cars. Since it's solid state that also means it's far more stable and safer than current batteries. The solid-state unit should also be able to work in as low as minus 30 degrees Celsius and up to one hundred.
The electrolyte materials still pose challenges so don't expect to see these in cars soon, but it's a step in the right direction towards safer, faster charging batteries.
Graphene car batteries
Graphene batteries are the future. One company has developed a new battery, called Grabat, that could offer electric cars a driving range of up to 500 miles on a charge.
Graphenano, the company behind the development, says the batteries can be charged to full in just a few minutes. It can charge and discharge 33 times faster than lithium ion. Discharge is also crucial for things like cars that want vast amounts of power in order to pull away quickly.
The capacity of the 2.3V Grabat is huge with around 1000 Wh/kg which compares to lithium ion's current 180 Wh/kg. The best part of all this is that these batteries should be ready to go by mid way through 2016.
Graphene batteries have already been demo'ed to the press.

That's just 2 examples of batteries being developed. The Government are going to have to get their finger out to provide the infrastructure and more importantly power generation solar and wind won't be able to keep up wwith the increase in power consumption.
