Fuel Cell Economics vs Batteries

We’ve been hearing a lot about fuel cell electric vehicles (FCEVs) lately, thanks in large part to Toyota and its Mirai. But how does a FCEV really compare to a battery-electric vehicle (BEV) like the Tesla or a LEAF?  I wanted to look at the economics between FCEVs and BEVs, and then […]

Why Aren’t Rural Electric Cooperatives Champions of Local Clean Power?

When it comes to ownership, there are few better structures for keeping a community’s wealth local than a cooperative. So why is it that America’s rural electric cooperatives are tethered to dirty, old coal-fired power plants instead of local-wealth generating renewable power? There are a lot of answers to this […]

Daimler Subsidiary Li-Tec to Cease Production of Battery Cells

Daimler subsidiary Li-Tec will stop producing Li-ion battery cells in December, closing the only German factory currently producing cells for EVs. “Our cells are very good, but at current production figures far too expensive,” Daimler Manager Harald Kröger told Der Spiegel. “We have realized that a car manufacturer does not […]

Researchers gain fundamental insight into key reaction for Li-air batteries

A team from Delft University in The Netherlands and the University of Waterloo in Canada has used operando X-ray diffraction to show that oxidation of electrochemically-generated Li2O2 in high energy density Li-air batteries occurs in two stages, but in only one step for commercial (crystalline) Li2O2. This discovery reveals a […]

This air-breathing solar panel stores its own electricity, cutting the cost of solar power significantly

It’s a solar cell! No… it’s a rechargeable lithium-air battery! No… wait… it’s both: It’s the world’s first all-in-one solar battery! The new device, developed by Ohio State University, is essentially an air-breathing lithium battery that recharges via a built-in solar cell. This is significant, because one of the biggest problems […]

Lithium-Air Batteries Planned By Volkswagen

It has been confirmed that Volkswagen is working on a powerful new battery for its EV fleet. Speaking at the Geneva Motor Show, Dr. Heinz-Jakob Neusser said that “an 80kWh unit is under development using our own technology. It would provide between three and four times the battery power in a given package.” […]

Lithium-air battery pushed as electric vehicle breakthrough

Research presented at the meeting of the America Chemical Society suggests that the current dominant technology for electric vehicles, lithium-ion, could be surpassed by batteries employing air as the cathode. At present most electric vehicles on the market today have a range less than 200km on a single charge. To […]

Better batteries through biology?

Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric cars with a much greater driving range. But bringing that promise to reality has faced a number of challenges, including the […]

IBM creates breathing, high-density, light-weight lithium-air battery

As part of its Battery 500 project — an initiative started by IBM in 2009 to produce a battery capable of powering a car for 500 miles — Big Blue has successfully demonstrated a light-weight, ultra-high-density, lithium-air battery. In IBM’s lithium-air battery, oxygen is reacted with lithium to create lithium […]
