Bullshit or advanced technology
Most likely a combination of both of that. I decided after the last one I watched never to watch a video by that content creator. But looking elsewhere:

"Most EV batteries have a specific energy of under 300Wh/kg. CATL says its new battery almost doubles that figure, with a specific energy of 500Wh/kg

Unfortunately, the company has not released many other details, including what this battery would cost, how many times it can be recharged, or how much power it can produce (how fast the stored energy can be used)."

So not sure what the capacity is 500% of, maybe someone who has watched the video can comment. But the number looks very like the Wh/Kg in the above quote.

There have been a number of new battery technologies announced over the last decade but the big problem is production-ising what you achieve in the lab in to an actual product. Sodium Ion is only just becoming available but suffers from density and form factor issues….but it does hold some promise. Generally there are 5 key battery parameters and in all the cases I know of you can achieve 3 of the parameters but must sacrifice on the other 2, these being Capacity, Density, Specific power, C Rate and cycle life.

With Sodium Ion apart from the form factor issues it has half the cycle life (ish) and a lower Power density by about 25%
Only the Sith deal in absolutes.

A fire on a cargo ship carrying almost 3,000 cars off the coast of the Dutch island of Ameland has left one sailor dead and 22 others hurt.

A major salvage operation is in full swing in the North Sea. The fire on the vessel could reportedly burn for several days.

Crew members were treated for injuries including breathing problems and burns.

A Dutch coastguard spokesman said the fire was probably caused by one of 25 electric vehicles on board the ship.

Last year, a cargo ship carrying 4,000 luxury cars caught fire and sank off the Azores. Lithium-ion batteries in the cars caught fire on board the Felicity Ace.

...but it appears that there is no confirmation they were the initial cause of the fire. Also, to be fair, EVERTHING on that ship caught fire...

Two different reports on the same event

BBC: A car transporter fire involving seven electric vehicles has shut part of the M1.

bestmag.co.uk: A car transporter carrying electric vehicles caught fire, causing the seven electric vehicles (EVs) to go into thermal runaway and ignite.

A quote from the last report

"Statistics compiled by AutoInsuranceEZ found that for every 100,000 EVs sold, there are about 25 fires. That compares to 1,530 car fires per 100,000 petrol-powered vehicles sold. Petrol-powered cars typically catch fire due to fuel leaks or crashes."

Another reason to buy one .

We have used £50 in electricity (on average ) per month doing nearly 1500 miles per month all over the north west .

Impressive, I ran the numbers based on loads of assumptions.

Petrol at 50 mpg would work out a over three times that cost, £165 or so.

I then worked backwards, don't know the kWh/km rating for your car, so I used the 16.6kWh/100km figure of a Tesla model 3. that works out as a electricity price of 12p per kWh, and Scottish Power has a 9.4p per kWh offer.

If I was still doing 22k miles a year it would be a simple decision.

It's adoption social worker Mrs who deos the milage , my visits are confined the 6 km walking Milo .

Although I haven't been for 3 days because I have severe vertigo . On Tuesday a 6 am when I fell on the Mrs dressing table , I thought for a minute or so I was having another stroke . Checked my blood pressure which was okay that and my sense of panic convinced me I wasn't having a stroke ( during the original stroke I had an unwarranted sense of calm and unconcern )

Thereafter I realised I had vertigo . Had it twice before , so I'm expecting it to spontaneously disappear

Whilst EVs can catch fire whilst sitting unused in a garage, without being on charge.
