Welcome to Thunderdome

Inevitably every time there is a thread about electric cars someone comes in to say "electric cars are worse for the environment anyway because of the production!" I would like to pre-emptively provide some info on that.

Wether or not an electric vehicle is beneficial in the long run depends heavily on where you live and what the source of your electricity is, however, in most cases it's still a net environmental positive to replace an inefficient car with an electric car. You can do the math yourself to figure out how long it would take for the equation to "break even" using data from the department of energy, anything past that point is benefiting the environment. I live in Nevada, which at it turns out is slightly better than average on its energy production.

I really recommend this video, and make sure you check the description which links to a lot of sources and tools. Even if you don't plan to get an electric car it might be a good idea to do the math to determine when the break even would be for your location. It might give you an idea of the larger environmental state of where you live.

I personally recently got a second hand all electric vehicle, and it replaced a VERY inefficient and older with questionable safety vehicle. I'm very happy, I love the new car, it's fun to drive, its much safer, and I feel happy that considering I need a car where I live, it's not optional, and my car realistically needed to be replaced if not now within the next 2 years, that I made the best decision for the environment in the process.

I hope in the future to get rooftop solar to double down!

Did you edit in that among?

I once got to do five laps at MIS in an Indy car with a professional driver. We were near 200 MPH. That first lap things flew by, but you get used to the speed really quickly.

Uh, that wasn't an electric car though...

Enovix, based in Fremont, California, announced that it demonstrated in electric vehicle (EV) battery cells the ability to charge from 0% to 80% state-of-charge in as little as 5.2 minutes and to achieve a greater than 98% charge capacity in under 10 minutes. The cells also surpassed 1,000 cycles while retaining 93% of their capacity.

The achievement shattered the United States Advanced Battery Consortium (USABC) goal of achieving 80% charge in 15 minutes.

Other goals for USABC at the cell level include a usable energy density of 550 Wh/L, a survival temperature range of -40 to +66 degrees C, and a cost of $75/kWh at an annual output volume of 250,000 units. A full set of USABC targets can be found here.

The company demonstrated the fast-charge ability in its 0.27 Ah EV cells in its silicon lithium-ion batteries, which it said contain a novel 3D architecture and constraint system. The cells contain a 100% active silicon anode. Enovix said the material has long been heralded as an important technology in the next generation of battery anodes.

Silicon anodes can theoretically store more than twice as much lithium than the graphite anode that is used in nearly all Li-ion batteries today (1800mAh/cubic centimeter vs. 800mAh/cubic centimeter).
