After achieving a breakthrough earlier this week, Greater Bay Technology said it aims to launch the world’s first mass-producible all-solid-state battery this year.

Great news indeed

As long as they dont go boom, Im happy with this.

Well, even LFP or NMC does not go boom.

They are not the bomb but they are Fire....

Does this mean cheaper prices?

In theory as it has no electrolyte so cheaper to make but cycle life has not been proven. I would stick with proven LFP.

Not for a while, still working on the making it affordable in mass production.
Earliest if everything goes well will be post 2030 probably.

Prices are coming down in general though for lithium batteries, it's expected that it should drop another 20-40% by 2030.
Current prices are about price parity / slightly cheaper for EV, and now with oil going up in price again, it's cheaper.

Right now the missing bit is just having cheaper cars by manufacturers, Chinese automakers are putting pressure on everyone else, and we're seeing e.g. VW's ID Polo launching for 25k EUR in Germany. When it gets to South Africa / what the price will be, we'll see.

Still need cars in the like 15k range, but I am more doubtful that we'll have many there, VW's ID 1 / whatever equivalent is expected at 20k in 2027.

Imagine how good LFP will be in 2030.

Yep, updated my post, I am not expecting solid state to actually be better/cheaper until late 2030's probably (and maybe we'll have a completely different tech), think it will be LFP for a while yet as they've not yet hit the limit on that.

If it has a higher energy density, then theoretically they can get the price down.

Donut Lab's 'miracle' solid-state battery is fraud, says insider, Donut Lab denies

Donut Lab promised a battery with incredible numbers which is ready for mass production. A former employee of a supplier says otherwise.

If it has a higher energy density, then theoretically they can get the price down.

Didn't say that wouldn't be true in the future, theoretically it should +50-100% energy density, but modern LFP is at around 200Wh/kg versus cheap end variant's 90-160.

Current competitive solid state ones are still in theoretical/before mass production, and they're going to be a lot more expensive for a longer while still.

LFP for all intents and purposes at the moment at the higher end probably covers like 95% of personal car user's usage, if that comes down in price, then solid state's main reasons will be probably safer and that it can theoretically charge a lot faster (though we're already having cars with 300kW+ in LFP like the XPENG G6, for most cars 300kW will give a full charge in 5-15 mins.

VW seems to be going NMC for the ID Polo's 52kWh model, with NMC being competitive at the lower end of solid state battery density, which makes it an uphill battle for solid state due to having to disrupt it (NMC is around +20% to LFP, solid state is +150-800% right now depending on source). So I'd expect solid state to first be in the true top-end of the price bracket and make its way down, the question is more will it be 2035 in the mid-range or even later.
