Samsung plans to begin mass production of its solid-state batteries for electric vehicles (EVs) by 2027, targeting the "super premium" segment. These new batteries are expected to provide a range of up to 621 miles, reduce charging times, and enhance safety by eliminating the risk of battery fires. Automakers, including Hyundai, Stellantis, and General Motors, have been testing samples and providing positive feedback. Samsung's solid-state batteries will be more expensive initially, but they promise to reduce vehicle weight and space requirements, potentially lowering overall costs. Additionally, Samsung is developing a semi-solid-state battery for entry-level EVs and is exploring other battery chemistries, including high-nickel NCA and LFP batteries. The company aims to create batteries that can charge in nine minutes and last for 20 years by 2029. Competitor LG Energy plans to start mass production of solid-state batteries by 2030, also focusing on premium EVs.

19 commentsThis would be more convincing if reviewers could order samples.
Yoshino seemed to be shipping a solid state battery, but several people have bought and disassembled the thing, and it has liquid/gel components. That was disappointing.
CATL has some good comments.[1] Wu Kai of CATL was quoted as saying that the maturity level of the technology and the manufacturing process can currently be categorised at 4 on a scale of 1 to 9. CATL wants to be at 7 to 8 by 2027, which is equivalent to the production of solid-state batteries in small quantities. CATL also mentions that they have 1,000 people in R&D working on this. This is a big project in China. The China All-Solid-State Battery Collaborative Innovation Platform is getting government funding and has all the big battery makers in China on board.[2]
Toyota's roadmap shows solid state batteries around 2028.[3]
There are solid state battery announcements all over, but the big players all admit that the manufacturing is really tough.
A US startup exists.[4] They mostly make press releases, not products.

A Tesla Model Y battery pack is 75 kWh and the highest rated connection within the typical American home with 200 amp 120/240 volt split-phase service is 50 amps over both phases: 12,000 watts.
75 kWh / 12 kW = 6.25 hours assuming the battery can be hit with maximum wattage continuously throughout its charge cycle (this is unhealthy).
To charge the Tesla Model Y 75 kWh battery pack in nine minutes the 240 volt cable would need to carry 2083 amps. This is hilariously far beyond the capacity of a 50-amp rated wire.
6 AWG copper wire which is rated for 50 amps has an 0.000395 ohms per meter (at 20°C). Assuming a ten meter length of wire, the resistance is 0.00395 ohms. Power dissipation in the wire P = I^2 * R. 2083^2 * 0.00395 ohms = 17,166 watts.
Temperature rise in the wire delta T = P / (A * k) where P = 17,666 watts, A = pi * 0.00411m * 10m. Assuming PVC insulation whose thermal conductivity is k = 0.19 W/m·K. Delta T is approx 700,615 degrees K. The surface temperature of the Sun is approximately 5773 K, so our wire would get about 121 times hotter than the surface of the sun if it did not instantly explode.
80 kWh / 0.8 = 100 kWh
To charge in nine minutes:
100 kWh * 60 min/hr / 9 min = 667 kW
A 400 V DC setup is common for this sort of application, so:
667 kW / 400 V = 1667 A
How physically large do the cables and related apparatus need to be in order to deliver this sort of current? What sort of training and personal protective equipment will people need in order to plug and unplug these cables? (Hint: Arc flashes are no joke!) What sort of service would you need to order from the electric company to be able to power just one of these installations?
Whenever I see text like this, my opinion of the editors, and thus the entire publication, immediately plummets. Did they think that 1000 KM was an accurate figure to be converted literally to three significant digits? Do they even understand the field that they are covering? Was it a machine conversion? What else should I not trust in their publication?
Even my Nissan Leaf which has notoriously slow AC charging (being single phase), the max 6,7 kW charging is very rarely a concern for me.
Could we get a price comparison per driven distance? Without it these numbers look good but I would be interested in the price too
Battery breakthroughs have been happening bi-weekly for decades
We're still doing this? Capacity by weight and volume, and efficiency per distance are much more meaningful. Charging is mostly a function of input voltage.
> very low risk of fire
