I'm quite impressed with the lithium titanate battery. Some bullet points........

Lithium Titanate batteries' benefits range from long lifetime to enhanced safety, low-temperature performance.
It's able to obtain up to 80% of its full capacity at a mere -30°C.
Entirely free of carbon to avoid thermal runaway or overheating which is a main cause of fires in traditional energy storage systems.
The recharge efficiency exceeds 98%, a record-breaking advancement in the field of renewable energy.
From that lightning GT model......The standard battery specification includes two 22 kWh Altairnano lithium-titanate battery pack 'strings' which will take about ten minutes to recharge, assuming the amount of power required is available. The 9 kW standard onboard charger can fully recharge the batteries in five hours from a dedicated wired socket ( 32amp). An optional onboard charger connected to a suitable dedicated domestic power source can recharge the car from zero in 2.5 hours.

What else do we want in battery if we had a purpose made high amp power source to recharge????

Personally I think lithium has now been accepted as mainstream for the next 10+yrs and like oil once $$$ has been poured into the commodity they will just keep improving it. R&D investment will continue rolling in big time into Li technology and mass production should enhance natural improvement through lessons from actual application and refinement.

Crikey I'm glad I got onboard early enough with this one.
