Yeah, I too, found it to be pretty disrespecting of facts.
- no mention of efficiency of gas engines (20%) compared to EVs (85% or
so).
- no mention of the extraction costs for fossil fuels, environmental or
fiscal.
- "exponential" inefficiency as battery weight increases; true, but
wildly exaggerated
- manufacturers start with a limit to 80% usage and relax the limit as
the battery gets older. Really?
There were more, which you listed, and probably others I don't remember.
I wonder how many people read this and lap it up without further
thought.

It's puzzling that the author of this article, Isidor Buchman,
allegedly
sets out to write about the differences between mobile phone batteries
and
EV batteries, but spends over 40% of his piece dismissing and
denigrating
EVs.
Worse, he rehashes the same old misinformation and ignorance that's
been
aimed at EVs for 5 decades.
Look at this junk. This is the language of a PR hack, not a scientist.
Some of it's outright wrong; other parts are just meaningless prattle.
(He
doesn't write, "the vehicle becomes less efficient," but rather "the
vehicle
becomes inefficient." Eh? Furthermore, no evidence for any
declaration is
presented.)
This [increased range] requires larger batteries that grow
exponentially with the distance driven.
... and the vehicle becomes inefficient with increasing weight.
There is a threshold as to battery size and weight in a vehicle; going
beyond a critical point has a negative return. The vehicle becomes
environmentally unsustainable.
Batteries have low calorific value compared to fossil fuel, and it
makes little sense to power a freight train, ocean-going ship or large
airplane with batteries.
A study reveals that replacing kerosene with batteries could keep an
aircraft airborne for less than 10 minutes.
Cost is another issue and batteries take long to charge.
A fill-up that is quickly and conveniently as topping a tank with
liquid or gaseous fuel is impossible with an electrochemical device.
Charging a fleet of EVs could dim a city.
His tired, old, misinformed anti-EV screed just keeps on going. It kind
of
makes you wonder where this "battery expert" gets his funding, doesn't
it?
