Cool car but could easily be mistaken for an Aston Martin. A premium car, especially one that's not well known, needs a look that sets itself apart. And that open mouth look is old. The battery tech sounds promising though.

If you are sitting on a breakthrough in battery technology you don't need to build a new car company first as a method to sell batteries. The energy density in the Panasonic 18650 cells Tesla uses is about 250 wh/kg and they are claiming a shocking 1600. An 80% charge in 4 minutes (3.5x the world record) making very little heat. They are claiming 5000 cycles before hitting 80% capacity and I think Tesla is closer to about 2600 or 3000. Engineering is often about finding the right balance of trade offs. When someone claims to have a miracle technology that delivers a massive breakthrough in every measurable way they might as well be asking for money to build a perpetual energy machine. If Desten actually had this battery technology and could prove it they would be well on their way to being the worlds first Trillionaires. Instead of waiting for someone to get a new car company off the ground to sell the battery they would be selling to existing companies like BYD and Tesla.

I have no interest in the car, as it is not the kind of low cost family car that is needed to replace existing fossil-fuelled cars with EVS, to mitigate global warming.
The battery is extremely interesting. There would be no point in a battery that charges in 5 mins, as, unlike liquid fuelled cars that require the driver to attend to the fuelling process, EVs are plugged in, and left to charge up on there own, either slowly, over night, or quickly, while the driver enjoys a rest stop. There is no point in any EV charging up faster than 15 minutes, as that is the minimum time anyone is likely to stop for a rest. Having said that, no current EV battery will charge to 80% in 15 minutes, and this suggests that this is an entirely new battery technology that would make all others obsolete. Now, that is extremely interesting.

Andy in my opinion you are incorrect. I want my vehicle refueled in 5 minutes or less. I do not take 15 minute fuel breaks 99% of the time I refuel. That said, once a battery exists that can be charged in 5 minutes, and I firmly believe this is just around the corner, you can kiss the internal combustion engine goodbye. Good riddance.

Assuming that all the data can be believed this would be very useful if deployed in cars that were affordable to the general public, not in richman's toys.

I fully agree with guzmanchinky. In my travels in the west of USA I only stop for gas and a quick pitstop. 10 mins max. More than 5 minutes at a pump starts to seriously back up queues of cars waiting. If these battery specs hold then we are finally on the way to having practical evs. Range is useful, but minimizing stopped time is critical, but if you spend 5 hours for 300 miles then waste an hour, you have dropped your average to only 50mph or 17% less. Would you want to want to extend your 8 hour workday by 17% to nearly 9 1/2 hours. Not me.

The claims come out at >1MW charging rate (80*3600 kW.sec / 280 sec = 1082.6kW). If this is possible, which I doubt, then there must be considerable heating and poor turn-round efficiency.

Using those numbers, the charging rate is roughly a megawatt. Enough to briefly power a decent-sized data center. At 1000V, that would be 1000 amps going through a cable somewhere. Perhaps they have some kind of massively parallel system that recharges all the cells individually at some maximum rate. But just the infrastructure to get that many electrons in one place at the same time...

@Aross I can't think of a single valid reason to assume the data can be believed. If I said the company I am working with achieved a 20% improvement over the state of the art energy density with a 15% reduction in charge time it's a believable claim. If I achieved 7 times the density, with 1/8th of the charge time generating 1/3 of the heat with twice the battery life and I needed a few billion to launch an automotive production line first before proving it I'd be laughed out of any sane room of people. Anyone who did have this technology would be looking to release test data proving the claims and commercialize it as fast as possible rather than wait for a 5+ year spin up of a niche boutique exotic car company to pair it with. That would be like saying I cured cancer but first I need funding for a privately owned airplane manufacturing company because I'll need a way to transport it around the world. It's a sharp looking car but the battery claims are abject nonsense. Even if they don't have the chemistry 100% yet providing some verification that their claims aren't completely fabricated would be very easy through independent testing.

Electric cars are just too expensive for the vast majority of people. Even the new Tesla for US$35,000 is wayyy out of reach for most people.
In other currencies like CDN$, EUR, AU$, NZ$, Yen, etc. US$35,000 is a lot more than the annual after tax income for most people. For example, US$35,000 is about CDN$47,000.
