Batteries 2X the capacity could be just around the corner

With technology moving so fast battery technology has not had the chance to keep pace. Hopefully that is due to change soon and could eventually see up to 5 times the capacity of the batteries we have today.

Researchers in the U.S. has managed to use Lithium Sulfur to hold 500 Watt hour per kg that after 1,000 cycles holds charge to 300 Watt hour per kg. Now put this into perspective of Lithium-ion that we use now for our cars and gadgets, that has a capacity of around 200 Watt hour per kg. With Lithium Sulfur the researchers has demonstrated a gain of 2 times of that of Lithium-ion.

Not only that this can improve our battery needs, but Lithium Sulfur also has a potential energy density of 2550 WH/kg which is over 5 times that of the best of the best Lithium-ion. Also Lithium Sulfur is a lot safer and won't suffer from the same effects of overheating as Lithium-ion does.

With better research this higher limit may be achievable and with the researchers now asking for people to weigh in support, I could see within the new couple of months or maybe early 2015 that we could have batteries at least double that we have today. I do hope they gain the support they need as this is truly game changing.
