IM motors has decided that semi solid-state batteries are ready for prime time. In an omen of what Western automakers will need to contend with, it's now launched a futuristic luxury coupe with a next-gen battery pack and crab-walking capability. The high-density lithium batteries we enjoy today were an absolute technological revolution. They blew rechargeable nickel-cadmium and nickel-metal-hydride batteries out of the water, offering such a leap in energy storage by weight and volume that suddenly all sorts of things became possible.

Hire more child labor so we can get cool batteries for our smartphones too
It’s also mostly stolen technology, from us.
The powers that be have absolutely no intention of building any more real electricity generation. They want to limit every freedom possible, especially the freedom of inexpensive, reliable, abundant energy.
During the very cold winter, Canada’s solar and wind power generation fell to......ZERO.
The dirty BIG secret is that the wind power mechanism must not be allowed to freeze, so something has to keep it warm, even if it is not turning. That ‘something’ is oil and natural gas.
I would love to peak into the future, during the next great cold cycle. I imagine The Comedy Channel running videos of AlGore and his minions stating “the Earth has a fever”
NOT really Solid State:
IM calls the battery pack in question “Lightyear”. It’s not a strictly zero-fluid solid-state chemistry, instead utilizing a semi-solid layout that includes solid material suspended in a liquid electrolyte.
The 900-V Lightyear pack has a capacity of 130 kWh for a total range estimated to exceed 1,000 km (620 miles). Just as impressively, it’s said to be capable of adding 400 km (249 miles) of range in just 12 minutes when wired up to a properly quick ultra-fast charger.
No details on what the chemicals are in the pack, or HOW big of an ultra-fast charger it takes to reach that 12 minute number. It’s all in the details with EVs.
Bipolar solid state cells will have twice the energy density of NMC cells and nearly three times that of LiFePO4. Bipolar as in think Big Mac vs quarter pounder where you have the meat on both sides of bread. Bipolar solid state cells will have twice the meat(active materials) vs bread(current collectors). Solid state in its real form is fireproof ceramics don’t burn and lithium bonded in a ceramic crystalline structure also cannot burn.
130kWh would take a Model 3 sized car 722 miles in the city averaging 180 watt hours per mile I have seen as low as 130 over ten miles of city grid lock traffic. Solid state cells can also take 5C charging rates or more. At 5C a 130kWh pack is 650kw the Tesla V4 standard has 1000v and 900amp ratings. This is a 900V pack so 900V*900amp is 810kw from 20% to 80% is 78kWh at 810kw 5.77 minutes to put that in across the fast charge 20/80 window. 78kWh takes a Model 3 @180whmi 433 miles. This is a 5 min charge and 400+ miles of range. Virtually no one drives more than 400 miles in one sitting at a legal hwy avg speed of 65mpg that’s 6 1/2 hours in the seat straight. At a urban average speed of 35mph that’s 12+ hours in the seat. no under driver is going to not stop for at least 5 minutes in a 12 hour shift NO ONE.
Solid state is the future and it will end the ICE for all urban use especially in the Asian megacities India megacities as well. 700+ mile range is not needed for any urbanites drive pattern it’s just not but having the larger pack allows crazy fast charge rates for Uber type use.
Tesla will stop selling cars to the general population once they get approved for their robotaxi fleet. One automated taxi in the city can generate $100,000+ in yearly revenue there is no way they’ll sell a Model 3 for $37,000 when they can use them as robotaxis with a 5+ year lifespan. Solid state will have 3000+ cycle lifetimes at 700 miles per charge even at 150,000 miles per year in taxi use a typical yearly mile count for a taxi. Even a 1000 cycle life would give a 5 year taxi lifetime.
Guys, i have been saying this all along. When we get to 600, 700, 800 miles on a charge that takes 15 - 20 minutes, in a reasonably priced car, the game is over for internal combustion.
The electric car is just getting started.
Not saying it’s good/bad, just facts. They are stubborn things.
“When we get to 600, 700, 800 miles on a charge that takes 15 - 20 minutes, in a reasonably priced car, the game is over for internal combustion.”
Inexplicably or ignorantly, you are completely ignoring infrastructure.
“The 900-V Lightyear pack has a capacity of 130 kWh for a total range estimated to exceed 1,000 km (620 miles). Just as impressively, it’s said to be capable of adding 400 km (249 miles) of range in just 12 minutes when wired up to a properly quick ultra-fast charger.”
This is easy to calculate.
You never drain a pack more than 10%’so the rates range is over a state of charge window from 100% to 10% or 90% of pack capacity it’s called the effective capacity of the pack. 113kWh effective over 620 miles is 188 watt hours per mile.
249 miles needs 46.8 kWh @ 188wh/mi add in 10% for DC/DC losses you need 51.48 kWh DC from the charger. Over twelve minutes that’s 0.2 of an hour so you need 5 times 51.48= 257.4kw this is V3 fast DC rates at 900V that’s 285amps the NACS plug has a 500amp standard and has been tested and certified up to 900amps the CCS standard used in the rest of the world is rates to 500kw with a cert to 1000kw before you move to a megacharger standard that tops out at 3,000kw with the plugs coming from the maritime industry where 10 megawatts is used for navy ships and cargo ships on shore power.
My solar panels made 139 KwH today so if I wanted to fill er up I guess I could :)
This is very interesting material.
Thanks for taking the time to post it.
Four wheel steering is a blast in the snow. /s
I had a Honda with it at one time and nearly died.
Tesla is building a 200 bay Bucces sized Supercharger they don’t have a habit of failure their engineers are world class. They will string in 66.4 kilovolt distribution from the closest substation and use on-site 66kv to 480/3phase in banks of 50 chargers that’s a 12,500Kva transformer a common size in medium voltage power engineering. They would need four of them on-site. The site they chose is near a nuclear plant you can bank pun intended they will hardwire to the substation driven by that plant.
That’s just a bit Pollyanna, considering what’s coming down the pike to disrupt politically driven research & manufacturing.
What about weight of EVs? And electric generation?
The bridge over the Mississippi River in Arkansas broke because it was made for 1976 amounts of traffic. Add weight of an electric fleet and you’ll need a new bridge.
And that’s just one of thousands.
Hybrids don’t have as much battery and you don’t have to worry about increasing the electrical grid.
And hybrids are good for sport cars like the Acura NSX and the Corvette Zora.
The average urbanites daily drive is less than 30 miles per day you need 7.5 kWh in a full sized Model S to cover that per day. That’s three 450 watt commercial sized panels worth of power per day or less.
With 600 miles range that’s 20 days nearly 3 weeks of driving for 96% of the population based on DOT data. With 5C charging you need 12 minutes over that 20 day period at a fast charger. It’s ludicrous to think that people offered a $45,000 car that is 5 times or more cheaper per mile when charged in your garage with the capability to take a 5C fast charge would not eliminate ICE it’s when not if.
Case in point retail power in Texas is down to 8 cents per kWh. Premium 93 is $4’15 today. My New Model 3 needs 180when/mi or 1.44 cents of power to cover a single mile. My S60 gets 28mpg in the city at 4.15 gal that’s 14.8 cents per mile and I can’t just walk away from it over night and have a full tank in the morning.
The rest of the world measures cost and fuel use over a fixed distance 100km. So using the world standard but in freedom units to cover 100 miles of travel retail power is 1.44 cents per mile add in 10% pack loss to be fair. 1.58 cents per mile and $1.58 for 100 miles.
ICE of identical size the S60 is one inch in all three dimensions to the M3 Tesla it’s also heavier by nearly 100lbs both ride on 18R tires Pirelli at that both are on P4s the same tire. 14.8 cents per mile is $14.80 for 100 miles.
Compare those two numbers and you will see why for urbanites EV make sense and with solid state cells they will crush ICE in every metric.
My S60 T5 Volvo AWD is heavier than the new Model 3 Tesla that is part of the stable now. They are within one inch of each other in footprint that’s length and width. The S60 is nearly 100lbs heavier the AWD drivetrain is heavy all those gears, difs, shafts ect.
It’s 1.58 cents per mile to drive my Tesla and 14.8 for the S60 you can see why the Tesla got added to the stable. I can also charge it over night at 5 cents or less per kWh or during the day for free off my solar panels. I would rather sell power at peak rates and buy back power in the middle of the night for one fifth the cost.
You lease a Tesla and turn it in after five years well inside it’s 8 year warranty. Mine is earning it’s keep today it’s out over the weekend on a peer to peer rental app for 4 days they can bring it back at 10% if they chose too. I included the CCS to NACS adapter so every plug in the DFW area be it CCS,J1772 or Tesla plug is open to them the car has all tech on including FSD so it will guide you to a charger if you get below 20% only a complete idiot cannot follow the on screen Nav to a open charger. Last night I was in Addison with it there was 30 fast DC spots within 2 miles of where I was sitting. No bad I charged it to 100% before the Turn driver came for it today. This weekend pays for the next three weeks lease costs so basically a free car for me over the next three weeks.
It’ll be a lot more interesting to see those sort of charging facilities spring up off of rural interstate off-ramps, very far from the nearest nuke power plant. That’s the real test - putting them where they’ll be needed, not cherry-picked locations that are ideal as proof-of-concept. Musk may be smart and ambitious, but large scale EV adoption is realistically a fifty-year project - IF we can afford it.
Grrr
*No need I charged it to 100% before the Turo driver came for it today.
It has 325 miles range I would be surprised if the renters drive 200 over the next 4 days so they won’t need to charge at all.
