CalBattery has designed a new li-ion battery with a silicon-graphene anode promising a major improvement in battery energy density. The design is based on what the company calls its "GEN3" silicon-graphene composite anode material for li-ion batteries, the technology breakthrough for which was developed at Argonne National Labs. The company entered the li-ion battery cells into the Department of Energy's 2012 Start UP America's Next Top Energy Innovator challenge, and is a finalist in the competition.

Independent test results show that CalBattery's cells have an energy density of 525 watt-hours per kilogram, and anode capacity of 1,250 mili-amp-hours per gram. Compare this to the typical commercial battery out there right now in the 100-180 watt-hours per kg range, and anode capacity in the 325 mili-amp-hours per gram range.

That means 300 percent more energy storage than current batteries, the potential to go 300 percent farther on a charge than current EVs and a huge cost reduction. "This equates to more than a 300 percent improvement in lithium-ion battery capacity, and an estimated 70 percent reduction in lifetime cost for batteries used in consumer electronics, EVs, and grid-scale energy storage," CalBattery CEO Phil Roberts told Torque News.

Thanks a lot for sharing such a great news, which is really going to revolutionize the battery powered UAV's.

certainly a step in the right direction assuming that there is a way to manufacture on a large scale for a reasonable price. unfortunately still 10x worse than gas ( even factoring in the difference in energy conversion efficiency ).

The new anode material is being commercialized mostly by consumer electronics OEMs at this time so just need to wait plus there are many other promising companies and new metirials to wait for hopefully not too much

Graphene will solve all of the worlds problems :D

I'm waiting for somebody to make covering material out of graphene sheets.  Then the entire aircraft could be nothing but battery!

Multirotors are about to go 10 leaps forward with this technology so i am just waiting for it to become available...

The market for these is so huge the RC fraternity will probably only get these years down the line :(

Can anyone with industry knowledge assess what this mean in regards to when this technology will be in my smartphone? I assume those will be one of the first applications.

I just keep reading about new battery technology all the time but i have no idea what that actually means in practical terms.

Tripple battery capacity with the same size as your present batteries.

This surely result in longer time between charges.

that is obvious but WHEN?
