Aluminium energy sounds cool because it is easy to recycle. I researched Alevo because the Innolith advertisement video is a bit suspicuous and oriented towards people who don't understand technology, the staff and labs don't appear in the innolith video, it's girls skipping in sunny green wheat fields and fake pixelated GUI's flashing : 10000 cycles, 50% and sunlit scenes from the Alps.
Innolith spent 68 million in their previous brand tu build a factory which produced zero final batteries. There is one battery in a shipping crate which is their only result for 68 million. It's photoshopped as well, its a photo of the Alevo shupping crate with a new Innolith logo pasted on top, with 3d perspective effects to make the photo look like a video.
They used a liquid electrolyte which required filtration of some sort to prevent it from degrading over time.
Their 68 million production plant in the USA was sold for 5mn. I wonder if they had the first round of cash from Obama's program.
I chased to find what their golden goose looks like and i found a very marketing based company. If they blew 68 million and have no equipment or staff experiences to share with new investors, i'd say they are chapter 11 all the way.
I have to agree it looks fishy.
There was a suspected scam from a Swiss EV startup company a few years ago. A hydrogen car which was supposed to have supercar performance. Thing is, it was supposed to have a 48V system... so the claims couldn't be true of course. Not possible to get high performance with such low voltage.
They even had Koenigsegg draw the design. Pretty nice looking car, and light too.
Probably good to be a Swiss company if you want to attract investors.

Not saying it's not likely a scam, but being 48Vdc doesn't mean you can't be a supercar. If I were currently building an unlimited budget build targeting maximum performance in an all weather capability vehicle, I would targeting 20-21s cells maximum.
When EV tech matures beyond copying 1990s industrial VFD inverter phase count and IGBT power switches, they will change to distributed stator windings, each driven by individual half-bridge sets.
The issues of switching currents over ~500A in a compact package are eliminated, by using as many distributed phase winding and half-bridge mosfet sets as required. Scaling to multi-MW power levels at low voltages is simple with this distributed topology, and a high efficiency high performance solution. The power bussing mass can be approaching nothing as the packaging distances between battery to controller to motor approach zero distance.
Each time mosfet silicon dice mfg tech evolves, this lower voltage solution becomes more attractive. IGBTs are still experiencing the same intrensic diode drop losses they did in the 1980-90s. SiC can start to have an advantage again as voltages go very high, but this invites it's own set of added BMS cost and harnessing, EMC-EMI compliance issues from greater E-field coupling, life-safety protection, and increased corrosion and dielectric breakdown failures.
Working with current requires some level of experience in designing low resistance uniform current density bus designs, but once you design and build it, you've got a strong dice roll for being done with drama from that system, while being extremely efficient and high performance and intrensically shock-safe to touch after a wreck or road debris damage cuts into the pack.
I've been doing EVs of all voltages now for the over a decade of experience, and I would make my personal no-budget ultimate EV dragster or hypercar 20-21s (77-73Vdc pack nominal). It's somewhere between a cost savings and cost penalty depending on the application, but if you're targeting ultimate performance and safety and durability as key metrics, it turns out amazing.
I've had the blessings of experiencing the performance and long term behavior of many builds now from DIY efforts to major Aerospace fueled budgets. I started a decade ago thinking running a 500V-1000Vdc powertrain would be a good idea. After a decade of doing it, I get excited about running 1/10th that system voltage, and turn down projects in that high of voltage range due to being packed with unnecessary but critical and difficult problems to be solving.
