The solid-state battery entered production by a VW subsidiary just when BMW started testing an i7 with solid-state cells. It boasts over 500 Wh/kg energy density, or double what the Tesla 4680 battery offers. Daniel Zlatev, Published 05/24/2025 🇪🇸 🇵🇹 ... E-Mobility Storage The second generation solid-state battery cell of one of the world's top 10 battery makers - Gotion - has managed to achieve a 50% capacity boost over the first generation's 350 Wh\kg.
After a year of validation, Gotion managed to tweak its Gemstone battery formula for a 60% improvement in solid sulfide electrolyte ion conductivity that brought on an energy density increase to over 500 Wh/kg.
For comparison, Tesla's 4680 battery cells with liquid electrolyte that power the Cybertruck pack half the energy density, while the LFP batteries that are in mass market electric cars or popular power stations like the Anker Solix C1000 come with even lower capacity numbers.
The solid-state battery has now entered pilot production, says Gotion, starting it slow with 200 MWh factory capacity that returns 90% yield, and the packs are currently undergoing road testing in electric vehicles.
The second generation Gemstone solid-state battery also achieved a 90% reduction in stacking pressure pre-tension force, allowing Gotion to pass all safety procedures like nail penetration, crash tests, or thermal runaway experiments with flying colors.
Given the increasing number of top tier manufacturers like CATL that have initiated solid-state battery testing and even pilot manufacturing, the self-imposed 2027 deadline for mass solid-state battery deployment in electric vehicles looks increasingly within reach.
This is when Toyota, Samsung, BYD and CATL said they will start mass solid-state battery production, although Toyota warned that the safer, high-capacity cell technology will first be installed in premium electric vehicles in the Lexus brand due to its higher costs.
Gotion is partially owned by Volkswagen, so the pilot Gemstone cells might have been installed in its vehicles for road trials. BMW also started solid-state battery testing with its i7 sedan on May 20th, indicating that the race who will be first to initiate mass production of an EV with solid-state battery is already on.

range increased to 1000km, but charging time also doubled?
Why do you need to charge until 1000km though? Singapore to Perlis is 860km. If you start your journey with a full battery, you hypothetically don't need to stop for a charge.

Old habits die hard. Plenty of people drive their ice car until the last drop of fuel and sometimes more thus stranding themselves

battery 1000km go to singapore to perlis just charge 90% only . if you weekday use just charge 30%-40% only
Any battery model best for my driving styles, 140-160kmh constant speed for 3-4 hours straight? Inb4 outstation far and drove fast cz slow speed are tiring for me

biggest issue is the low quality and material of China EV
Thats the crazy thing. Do you know that the main cost of any battery operated product is the battery? The whole cost of a top end Samsung and Iphone is not the screen or the chip. It is the battery.
A high end RM5000 phone does not have the same quality battery as a RM500 phone even though both has same milliwatt hours.
No cheap EV at RM30k with 0-100 KM/H in 3.5 seconds, 1000KM range, recharges from 0-80% in 10 minutes, 10 speaker and dual subwoofer B&O sound system, full Apple Carplay Ultra and Android Auto wireless, no talk.
It's always cost. You can say you have 2x energy density bla bla bla, but if it is 10X the cost, people are still sticking back with the older solutions.

10 years -15 years down the road u will have one..
talking bout this, i also wonder why they can't do it. Toyota have Hybrid which self recharge the battery. why they don't do something like this for full EV car? Can add solar panel on roof as backup.
Waiting for CCP EV scams!! Comment with long ass colourful essay to look intellectual in order to confuse people to start being spammed in this tered….
That's not true. EV's are simpler. Compare the number of parts in ICE vs EV. Night and day.
Wrong! Too many electronics still compared to ICE. Too many sensors too.
EV with simpler electronics only for older first gen ones.
EV more towards software than hardware. Software may contain bugs. ICE especially older models mostly on hardware problems which are fixable for cheap and DIY friendly.

There are more than 2000 moving parts in an ICE car. Who told you easier to fix? You driving a Datsun?

Engine moving parts won't breakdown easily with proper care and maintenance. The number failure for ICE is excessive usage without proper maintenance.
EV with multiple electronics will breakdown first. Shorts, weak battery, faulty sensors and more will force any EV into limb or protection modes.
By design, EV is simpler than ICE is correct but the operation is very complicated.
Ok older ICE, u only need 3 working sensors to start the car namely crank sensor, airflow or MAP and camshaft position sensor. That's all. The car will start and u drive to a workshop for major work done or DIY if capable.
On EV, it is mostly software and many many active sensors. U can DIY unless u have the parts and skill to do it.

And one more drawback of EV - the electronics & software - proprietary. Close system. No way can mod / DIY once they no longer support that model. EV - mechanically simple compared to ICE but electronically complicated and closed.

Hopefully the cost eventually becomes cheaper and can produce vios level ev.

If u replace the ECU and BCM, it is possible but need a lot of R&D.

yup, EV has less serviceable parts. if anything spoilt just change whole thing.. e.g if EV DC motor spoilt. you won't see service center go and dissemble and change the coil or magnet inside the motor, sure just tukar whole motor only.. everything count as a whole, sure less parts. if you count ICE engine just "an engine" the numbers of "parts" will drop significantly.

Similar argument people like you make when cars change from manual to auto transmission. You need to get with the times. Ev will get better and better, ice never improves.

ICE don't need improvements because it is perfect as it is. With a simple basic ECU, it will start up and run.
EV is like an alpha project and always kept evolving. Hardly will reach beta release any time soon. Because it is more software based, it has plenty of bugs.
I will move to EV if gomen lets me convert some of the old jalopies like the infamous VR4 or Pajero into EV. From here, I can pick the right controller, batteries and features.

When global car sales on ICE is reducing year by year, car manufacturer will be reluctant to pour more fund into developing new ICE car, u will forever stick with old type of engine and transmission with minor facelift changes.
Don't forget the parts for ICE will be increase because the volume is declining, spare parts will be sacred and maintenance for ICE car will goes up.

Right now ice cars still far surpass ev sales outside of China. Old trans and engine isn’t really a downside because ice engines have pretty much been perfected since the 90s. Just think why Toyota so reliable, is because they used proven old design for many many years.

yeah, nokia was doing fine until 3g data and Iphone came along. so far hard to see BYD and tesla as an iphone moment compared to a toyota. i can still pretty much use one to do 99% of the stuff EV does plus some other feature EV cant do. if FSD where totally autonomous driving can only be implemented on EV and not ICE, thats an iphone moment for ICE cars.

Yi Long Ma keep saying FSD coming soon coming soon until people now have to say FSD and "totally autonomous driving" together in one sentence.

I laugh a bit when articles come up about tesla fsd or byd god eye and then in the same paragraph say china etc enforcing stricter laws where drivers eye must be on the road and hand must be on steering wheel with full attention when FSD/god eye mode is activated. seems it would be more tiring than just driving. or its like really advanced cruise control.

Who needs FSD when almost 20 years ago eFukt already posted a video titled, "Fucking While Driving,"?
cheap EV RM30k with 0-100 KM/H in 3.5 seconds, 1000KM range, recharges from 0-80% in 10 minutes
QUOTE(empstar2 @ May 27 2025, 11:05 AM)
10 years -15 years down the road u will have one..
BYD just lowered their China prices, Seagull now Rmb56K (Myr33K) likely in anticipation for new models with better tech incoming. 0-100 within 7-8 seconds is fast enough, range say 600km WLTP and recharge to 80% in 10min
. EV cars with ASSB will be about 30%-50% more expensive than those with NMC or LFP batteries but longer range, lighter, last longer and much safer from self-combustion.
Hence VW will only be offering ASSB to premium EV cars first.
For non-premium EV car buyers, it will be worth it to pay more for ASSB. Hence habislah for today's EV car models with NMC and LFP batteries. .
The only thing i don't like about EV is the charging time. They should make all cars like toys cars where you can just change the battery anytime. Nobody owns the battery. Battery is just like 'petrol'. Say battery left 20%, go into station, swap with a 100% battery. Then we only pay 80% of it. The station will charge that battery for some other cars.
