Some skeptics have attacked EV cars on the basis of current battery capabilities. I asserted that with some work we'll fix those issues. And then today, I read this very positive new development

...development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80% capacity in only five minutes. When applied to batteries for electric vehicles, the new materials are expected to more than double their driving range.
...
"We were able to develop carbon-silicon composite materials using common, everyday materials and simple mixing and thermal processes with no reactors,...The simple processes we adopted and the composites with excellent properties that we developed are highly likely to be commercialized and mass-produced. The composites could be applied to lithium-ion batteries for electric vehicles and energy storage systems (ESSs)."
