Also, what happens when an EV taxi runs out of battery power in China? They actually have stations setup all over that you simply drive into and it replaces the entire battery pack... in minutes.

When price comes down and production comes up (assuming those things happen), then I would expect them to start appearing in phones as well.

Not quite energy density, but the energy density, cost, complexity when combined with the discharge profile generates a very "interesting" phase space.

There's a few promising technologies which have very, very good efficiencies but only like very slow predictable discharge cycles. These are excellent for say building giant GW batteries in the desert, but not so great for even car batteries.

Phones and tech have bursty power needs based on use, the cost of taking other tech down to the size of a phone is extremely high (especially if you're first to market unless you know you will sell millions of units). Not to mention the reliability of batteries typically decreasing as the size drops.

Cars tend to be in the middle with their discharge profiles being relatively smooth compared to say a laptop, but yes you still have economies of scale, complexity, reliability and supply chain and patents to contend with ;)

Other phones targeting the Chinese market have reached 8000.

But companies like Apple and Samsung like to just sit on their laurels and sell the same thing again.

Given it's still lithium based I'd still think twice before chucking a bucket of water on one that's fizzing :p

As for how this battery is better I'm not an expert, but good to read if true.

Maybe you are comparing the density of research batteries that weren't worth commercializing to highly developed lithium ion batteries?

How so? A full battery can run your seat heaters for about a month. That's a lot better than the hours of heat you'd get out of a full tank of gasoline.

Not to mention that you'll never get carbon monoxide poisoning from a gasoline engine with a tailpipe blocked with snow.

Newer models have heat pumps that greatly improve efficiency in cold weather. They also have better battery chemistries that store more energy in the same form factor. Unless you live in a very remote, very cold location (eg: rural Alaska), an EV is a fine choice.

If you developed a hyper-efficient ICE engine that didn’t generate a pile of waste heat, you’d have to actively make it less efficient in the cold, or install heating hardware and burn extra gas to power that hardware - but nobody would criticize that hyper-efficient engine for being “worse in the cold”.

Are they even doing that? A few billion dollars a year is meaningful but it's not dumping for an industry this big.

I consistently hear 2 main arguments against electric vehicles in the US. Range, and cost.

BYD & China is solving both. Range is important because we lack charging infrastructure still, and anyone who rents at an apartment complex, you are screwed and have to rely on public charging stations. Big batteries are important for these folks. People also still have range anxiety, so when a fuel efficient gas car will get ~400+ miles per full tank, only having more expensive cars with a ~250 mile range is a non starter for a lot of people in the US.

Cost is self explanatory. One of the better electric cars sold in the US, the Ioniq 6 STARTS at $38k, which is already more than a significant chunk of the population can afford - you're looking at close to an $800/month payment at current rates for entry level. BYD could sell in the US at around $20,000.

Given our recent election results, it seems to me that we don't want to.

At least 40% of Americans do not give a crap about addressing climate change. Many Americans see EVs as a waste of time and a direct attack on the US.

Because the unfair advantage distorts the market leading to a potentially otherwise noncompetitive product destroying the competition at which point they can (and will) jack up prices, so not only do you get more expensive vehicles, but you've also destroyed an entire industry and several adjacent industries at the same time.

It's not like you can't just snap your fingers and re-establish a vehicle manufacturing supply chain once it disappears.

I get people just want cheap vehicles, but the short-term benefit simply isn't worth it.

Point your gun where it belongs which is the oil industry and its lobbyists.
