This thread is about batteries, not the virtue of EV's or other EV related tech. Today's EV's are expensive, have limited range and relatively slow charging, and this is due to the battery. I've been reading about batteries for years now, and despite the frequent news reports of "battery breakthroughs" I'm more than skeptical, I'm 100% convinced the breakthrough won't happen anytime soon. The first discussion point is battery cost. The 60KWH battery in the Chevy Bolt costs GM $10,800 (or more) and it "lists" at a staggering $15,734.29. This is not unusual or abnormal in the EV battery world. It's spot-on normal. Meaning that a 180Kwh battery, necessary for an F150 sized pickup to go 300 miles at 70mph, will cost a staggering $32,000 or exactly as much as a new base model F150. A battery with double the energy would be half the size and presumably cost half as much. However, the mass produced battery price curve is leveling out. https:/
The second point is the constant battery breakthrough reports. While the reports seem to have a bit more truth to them today, as they always state "more development required" there is an entire segment of the population that believes the fantastical reports, without an understanding that these reports exist mostly to generate funding. One very active company has invested $125 MILLION (correction, er, an additional $170 million on top of the $125M) directly into research over the last 10 years. The result: a 20% increase in battery capacity over the next 10 years. Even more interestingly, they discovered the very same things that are currently in the Tesla 2170 Cells already in use. NOTE: the higher 40% claim remains technically elusive. As you can only move so many ions. (6 graphite atoms per lithium ion)
Even the investors are being told the improvements are at best, a decade away.

The third point is charging speed. By nature, battery charge rates taper down as the battery nears full. Some fast charging stations can force fill a battery to nearly full, knowingly shortening it's life. This may be occasionally acceptable, but don't be fooled, charging stations are ever more powerful, and ever more damaging to batteries.
Here is where we are: Ever larger batteries will get us more capability and range. But the dream of a fast charging, long life, ultra high range, inexpensive EV will remain elusive for quite some time.
