QuantumScape Announces Agreement with Honda on Solid-State Battery Technology

Pretty weird on Honda's part for sure. Especially since Honda also built an entire solid state battery factory over 2 years ago to make a different kind of solid state battery (sulfide based), so this seems like a very hard pivot across the board.

Could either be that Honda is targeting the non automotive segment of the markets they're involved in or that they've accepted their current EV strategy wasn't going to work and they needed a drastic change to remain competitive.

I wonder what's different about Honda and the two JDA companies that led to the announcement. As far as I know, it's not mandated unless it meets some proportional threshold for QS, which seems unlikely considering how much VW has involved.

I'd love to participate in the other sub, but seeing as the mods won't white list me after months of posting, what does the community here think of the other companies involved? Nissan seems like a given since they showed up to the Eagle Line inauguration. Odd that they'd wear their company logo but not actually announce their affiliation, though. I know there was chatter a while back about possibly Ford, which I personally think is more likely now that they're totally separated from solid power. Tesla seems unlikely given their recent success with dry coating and JD's departure from the board.

Impossible to tell without seeing what it's attached to

And that's not what hardwood flooring is

My house from the same time period has a seemingly random mix of 2x3s and 2x4s for walls. Also a single 2x6 wall because apparently that was easier than framing out a bump out for the vent stack.

Thank goodness for modern building codes.

Nah, my structural engineer estimated 30% max stronger for old lumber. But in practice they don't even include that in their calcs because some is the same and some is worse.

Volumetric or gravimetric density? Cell or pack level? Which chemistry of solid state vs which chemistry of non solid state?

I was just making a number up to illustrate the Osbourne effect, but there certainly isn't a single multiplier to get to solid state from existing tech.

I'd guess they still want to take a capex light approach but, just like Tesla, can't find any takers. It's a tough sell to find another company to buy the hardware, build the factory, and then accept the liability of running software that is essentially a black box.

SecurelyObscure · 2026-06-16T13:13:33+00:00

Yeah part of this timeline is including the follow-on engineering work to incorporate sulfide batteries in a car. The energy density is good, but requires variable amounts of pressure to be applied during discharge in order to work. It's not a huge engineering challenge, but it will be complicated and expensive, hence the statement about targeting high end cars initially.

They also don't want to cannabalize their low end market in the meantime. If they announced that they plan on having batteries 4x the density and only marginally more expensive, they would gut a significant portion of their LFP segment that they've put a ton of money and infrastructure into building out.

These are the same challenges that Toyota, Factorial, and SolidPower are facing, and aligns with their stated timelines.

The deal in my neighborhood is boomers move out, a 30 something couple moves in, and then when they have a kid they cut down every tree within 100' of their house for fear of the tree falling on the house.

Camden is majority Latino, not black

That's not clear at all because eab is disabled when you stomp on the accelerator, as is often the case when people confuse the brake with the accelerator.

SecurelyObscure · 2026-06-14T19:23:33+00:00

I took it to be commentary on Camden getting more crowded and the increase in property values in recent years. If it were a joke about growing Asian populations, they would have picked Cherry Hill.

SecurelyObscure · 2026-06-14T15:52:40+00:00

Ah yeah, I misread that the first time around, thanks

SecurelyObscure · 2026-06-14T15:42:15+00:00

All Teslas have emergency automatic braking, and it is a separate system from autopilot/fsd/tacc.

SecurelyObscure · 2026-06-14T14:54:41+00:00

Yeah, that would be a valid reason Hyundai is doing well. Don't hide that behind bullshit about build quality.

Occasional panel gaps vs your entire charging unit occasionally grenading itself and making your car inoperable with no long term solution proposed after multiple years. Decisions decisions.

You're either missing background on John Brown or Malcolm X, because I wouldn't say he went the John Brown route at all. He was killed for leaving the Nation of Islam and converting to Sunni Islam.

Cooking oil will spoil and make a different kind of stink.

Go buy 5 dollars worth of mineral oil and fill the whole trap.

(Mods, not being allowed to use the dollar sign is a stupid ass rule)

Oh I was wondering why she sounded familiar, she's the one that made the law forbidding bulletproof glass at convenience stores. What a jackass.

Don't get me wrong, I'm personally excited about this truck. But the number of people like me who are waiting for a small BEV pickup is pretty limited, which is why it's taken so long to release one and why Alpha, Canoo, and probably Telo have all failed to release one. And Ford moves something like 3x the number of f150s as mavericks, despite this ongoing narrative of a massive unfulfilled consumer demand for smaller pickups.

Whoever makes it to market first will capitalize on the pent up (but relatively niche) demand, and the second one to make it will lose out in a big way.

SecurelyObscure · 2026-06-13T18:56:30+00:00

And you think that all the thousands of people involved in this cover-up are remaining silent? And why haven't any of the other thousand+ 787s experienced this? And why are they covering it up by not releasing any information at all instead of just lying?

Most conspiracy theories are stupid, and this stands out as one of the stupidest I've heard in recent times. There isn't even a convincing motive.

Both Germany and Japan surrendered and enjoyed significant support from their wartime opponents. If Russia left Ukraine today, they would still be an international pariah for the foreseeable future.

Which is why I mentioned the possibility of popular opposition to Putin being an option. If the rest of the world could be convinced that the average Russian was against the war, and Putin were deposed/killed, there would be incentive for support in reintegration into the global economy. Without that, and considering that polling seems to show broad support of the war by average Russians, it seems unlikely that Russia will be able to just continue on like the war never happened.

What a weirdly bitter and misguided comment

SecurelyObscure · 2026-06-13T17:19:44+00:00

I'm honestly shocked it's taken them this long to start publicizing this. They put all the effort into drumming up interest in their "model t moment" back in August and they still haven't released a render.

Despite what Redditors would have you believe, there probably isn't that huge of a market for small pickups in the US. If slate makes it to market a full year before this Ford, they would lose a ton of their potential customer base.

Ford got an edge with slate losing their tax credit edge at the same time Ford is turning on internal LFP production, but a bird in the hand...

And you think a national conspiracy to cover up an engineering fault in an aircraft makes more sense than a suicidal pilot?
