Researchers at Mie University in Japan have developed a new protected lithium electrode for aqueous lithium-air batteries, which they presented at the annual meeting of the American Chemical Society. Lithium-air batteries are attracting a lot of attention, because of their potential to deliver much higher energy density than current Li-ion designs. Most recent studies have… Read more »

Nashville buys seven Proterra electric buses
Proterra has announced the sale of seven electric buses and a charging station to the Nashville Metropolitan Transit Authority (Nashville MTA). The buses will be built at Proterra’s manufacturing facility in Greenville, South Carolina, and delivered this year. The funds for the new buses came from a federal Clean Fuels grant and matching funds from… Read more »
Cambridge researchers get a close-up view of silicon expansion in Li-ion batteries
Researchers have been interested in silicon as a replacement for carbon in battery anodes for many years, as it has roughly ten times more storage capacity. However, there’s also a tragic flaw: silicon atoms absorb lithium atoms, causing the silicon to expand up to three times in volume, degrading the battery. Now a team at… Read more »
Porous Power’s new microporous membrane will boost Li-ion battery performance
Q&A with Bernard Perry of Porous Power Technologies. In 2006, Porous Power Technologies was formed around a new microporous membrane material designed specifically for use as a lithium-ion battery separator. At that time, most battery separator materials were originally intended for other applications and adapted when the lithium-ion market began to develop. The company’s founders saw an… Read more »
Lean and mean: The EV charging pioneers at ClipperCreek
A straightforward look at the EVSE market from the charging pioneers at ClipperCreek In a charging station industry filled with multinational conglomerates and 100-year-old automotive suppliers, the independent company ClipperCreek stands out. Relatively speaking, it has had a long history in the EVSE industry – a history that has shaped some definite views of the… Read more »

Throughout Italy, racing pervades the culture. Within a 30-mile radius in the Emilia-Romagna region of northern Italy, you’ll find the headquarters of Maserati, Ferrari, Lamborghini, and Ducati, representing… Read more »
Former Secretary of Energy Steven Chu joins board of Amprius
Dr. Steven Chu, a Nobel Prize winner in Physics and the former US Secretary of Energy, has joined the Board of Directors of Amprius, a developer of lithium-ion batteries with operations in California and China. Amprius, co-founded by Stanford Professor Yi Cui, introduced its first generation of batteries in May 2013, and it is now… Read more »
CalBattery’s new SiGr anode material hopes to break the battery bottleneck
California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »
DOE offers $10 million in research funding for batteries, motors and power electronics
If you’ve got an idea for cheaper, lighter, safer or more durable batteries or electric powertrain components, you may be eligible for a piece of a new $10 million pot of research funding. The DOE’s Vehicle Technologies Office (VTO) has issued an Incubator Funding Opportunity Announcement (FOA) for projects that address any of several “areas… Read more »
London taxicabs plug in as Metrocab launches real-world trials
London’s classic black taxicabs are slowly but surely going electric. The new Range Extended Electric Metrocab, a plug-in hybrid taxi designed and built in the UK by Ecotive, a subsidiary of electric powertrain developer Frazer-Nash, will begin real-world trials in the British capital this month. London’s famous black taxis must conform to a host of… Read more »
