3rd Generation electric car batteries promise 300-mile range and 70% less cost


I want one of these

Would you be interested in an electric car that travels 300 miles on a single charge but its battery costs about 70 percent less than today’s packs? It’s something to look forward to in the next few years, says lithium-ion battery research company CalBattery.

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.

…”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.

Increased efforts to get EV tech into the marketplace have Nissan offering dramatically cut-price leases on their Leaf – and, now, some California Focus Electric dealers matching the rate. For as long as the cost of money is zilch, leases start to make as much sense as purchase.

The Ford EV’s aren’t yet available in my neck of the prairie; but, if they start to show up in the next year – at California lease rates – I’m beginning to think it worthwhile. Especially with consideration of rolling the deal over into a new purchase with Gen 3 batteries in a subsequent 3 or 4 years.
