ARPA-E awards $42M to 12 projects for advanced EV batteries; EVs4ALL program

Green Car Congress

Virginia Tech will develop EV batteries using cobalt- and nickel-free cathodes, fast-charging and all-weather electrolytes, and coal-derived fast-charging and high-capacity anodes. Additionally, using a coal/carbon/silicon anode will resolve environmental issues of coal waste and reduce anode cost by 75% compared with a graphite anode.

How Efficient Is Your EV? It’s Complicated

Cars That Think

But the efficiency equation is more complicated than that because, unlike petrol pumps, recharging stations do not transfer energy perfectly. Some people will use this information to adapt their choices about where and when to recharge. For them, recharge efficiency might be just as important as MPGe rating.

Wind Turbine Blades Destined for the Afterlife

Cars That Think

A planned network of landing spots will let eVTOLs recharge their batteries between flights, keeping people above the hustle and bustle (and traffic tie-ups) that come standard with taking private cars or taxis on city streets. This flash Joule heating process can also extract rare earths from fly ash, a by-product of coal combustion.
