A bit shy of two years ago, battery startup Envia Systems looked quite promising. The Silicon Valley company had produced a 400-watt-hours-per-kilogram lithium ion battery and claimed it could be placed inside an electric car that would cost $20,000 and be able to travel 300 miles on one charge.

A Voltron for lithium batteries? 14 companies, Argonne National Lab join forces

Perhaps a flock-like approach to building lithium batteries for vehicles is what it'll take. A new alliance has been formed between the Argonne National Laboratory and 14 US companies to try and "perfect" li-ion batteries for cars, the lab announced this week. The alliance, called The National Alliance for Advanced Transportation Battery Cell Manufacture, will ask for between $1 and $2 billion from the US government over five years to help with the task. Much has been made of the way that Americ
