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 […]

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 […]

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.” […]

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 […]

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 […]

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 […]
