Silicon has a theoretical charge capacity ten times higher than typical graphite. That is why a mind-blowing number of researchers are working towards replacing more and more of the graphite used in today’s lithium-ion battery anodes with silicon. In the last issue of Charged, we discussed Tesla’s announcement that it had begun to use small… 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 »
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….

NRG EVgo on the move: Its DC fast charging network passed major milestones (Full Interview)
Q&A with Arun Banskota and Brendan Jones. In the past year, the NRG EVgo network has quietly passed some major milestones in the EV charging industry. The company now has more public DC fast charging sites than anyone else – even more than Tesla’s vast Supercharger network. EVgo also has the highest number of CHAdeMO and… Read more »
UQM Technologies grows from pioneer to power player in vehicle electrification
With its integrated electric propulsion systems spreading across the globe in all conceivable vehicle types, UQM Technologies could be called the biggest little company in the EV industry. Over the past few years, the company seems to have entered its prime, as in one of those TV commercials where a deep, authoritative voice tell us… Read more »
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 »
BioSolar claims polymer cathode can deliver twice the range at a quarter the cost
Energy storage startup BioSolar (OTCQB: BSRC) will extend a sponsored research program at the University of California, Santa Barbara to further develop its “super battery technology.” The extension funds the research program until June 2016. BioSolar’s baby is a novel polymer cathode that leverages fast redox-reaction properties, rather than conventional lithium-ion intercalation chemistry, to enable… Read more »
Plug-in sales slow in June, but Tesla exceeds estimates
For the second month in a row, total plug-in sales fell short of last year’s figures. Overall US sales were 10,365 in June, 10% lower than May, and 16% lower than June 2014. The good news is that worldwide sales have shattered last year’s numbers every month so far this year. After a slow start,… Read more »
