Researchers from the University of Waterloo and GM’s Global Research and Development Center have developed a new silicon-based anode material that they say could enable batteries with almost 10 times more energy density than today’s state of the art. In “Evidence of covalent synergy in silicon–sulfur–graphene yielding highly efficient and long-life lithium-ion batteries,” published in… Read more »

European researchers: Our new Li-sulfur battery is more energy-dense, cheaper and safer
EU-funded researchers in the LISSEN (Lithium Sulfur Superbattery Exploiting Nanotechnology) project have developed a new lithium-sulfur battery that uses lithiated silicon as the anode and a nanostructured sulfur-carbon composite as the cathode. The team says its battery offers an energy density at least three times higher than that of current lithium battery technology, as well… Read more »
Scrap tires transformed into supercapacitor electrodes
Some of the 300 million tires discarded each year in the US could be recycled and used in electrodes for supercapacitors, using a new technology developed at Oak Ridge National Laboratory and Drexel University. The process is described in a paper published in ChemSusChem, titled “Waste Tire Derived Carbon-Polymer Composite Paper as Pseudocapacitive Electrode with… Read more »
Tesla tweaks its battery chemistry: a closer look at silicon anode development
In mid-July, Tesla Motors made a trio of Model S update announcements. The new options included a 70 kWh rear-wheel-drive base model, an upgrade for the high-end battery pack from 85 to 90 kWh (providing about a 6% increase in range), and Ludicrous mode, which offers a 10% improvement in the car’s 0 to 60… Read more »
2016 Chevy Volt: GM’s top electrification engineers on designing the all-new EREV
When the Chevrolet Volt was launched at the end of 2010, I must confess that I gave it little chance of success. It seemed like an awkward compromise – buyers who wanted to go electric would surely prefer a pure EV, and buyers who weren’t ready to take that plunge had every reason to stick… Read more »
Proterra CEO on the economics of the electric bus business
Venture capitalists assume a large amount of risk when they invest in early-stage companies. They do so because of the potential for huge returns. To ensure that a portfolio of investments delivers the greatest return with the least risk, VCs spend a considerable amount of time evaluating companies, looking for the key ingredients of success….

Human-machine interface experts on the nuances of displaying and interacting with EV data
Few have been working on human-machine interface (HMI) design for EV drivetrains as long as Brian Gallagher and Kevin Coelho. In 2007, Gallagher joined the startup Aptera Motors as employee number three. Shortly after, Coelho joined him as the seventh addition to the California company, which was building ultra-efficient three-wheeled electric vehicles. Five years later,… Read more »
Samsung says it can immediately double capacity of Li-ion batteries
Samsung Electronics has developed a silicon carbide-free graphene coating that it says could immediately double the capacity of lithium-ion batteries. That would be an impressive feat indeed, considering that capacity has increased only twofold since Li-ion batteries were first commercialized in 1991. Many researchers are investigating the potential of silicon as an anode material, but… Read more »
ChargePoint’s new Express 100 24 kW DC fast charger
ChargePoint has introduced a new addition to its line of EV charging stations. The Express 100 is a compact 24 kW DC fast charger aimed at businesses such as retail locations, restaurants and convenience stores. Earlier this year, the company announced the Express 200, a 50 kW DC fast charger with a maximum charging rate… Read more »
FIA Formula E Championship aims to change perception and push EV technology to new heights
A race towards progress: The all-electric racing series The greatest obstacle to getting more EVs on the road isn’t high upfront costs, range anxiety or a lack of infrastructure – it’s simple consumer awareness. Despite the fact that the Model S, Volt and LEAF are becoming common sights in many cities, a surprisingly high number of… Read more »
