The supplier of Lightning's battery, this is certainly good news, perhaps they actually are making progress.

As long as battery swaps can happen, this is great news.

I would not count on that in the slightest.

I quit reading all the reports of solid state batteries. My expectation of actually seeing these batteries on the road in cars is 10+ years. I hope I'm wrong but since the lightning's battery should last me 20+ years I'm fine waiting.

I try to look at EVs and new cars the same way. Life is too short to spent any attention capital on something that may go to production at a possible price. Once I see actual owners posting reviews online, it is an option. With battery new technology, going to production may be even more complicated. “Prototype expected by 2029”. Means we really don’t have any news.

I think we'll see solid-state EVs well before 10 years but there won't be enough data or manufacturing capacity to trust it initially. An additional 5 years is reasonable to gather enough data and refine the technology to stabilize it, so your 10 years is probable for mass production. NCM and LFP have had a couple of decades already to refine the technology and build manufacturing capacity.

LFP will continue to grow given the advantages of much higher age/cycle tolerance, and recent advancements in cold weather performance and energy density.

Solid state batteries have long been viewed as the breakthrough technology EVs need to reach the proverbial next level, given the fact that they’re very energy dense and compact in terms of packaging. That’s precisely why Ford has been happy to invest in such technology, doling out money to third-party companies like Solid Power, as well as its long-time partner SK On. We’re getting closer to seeing solid-state batteries become viable for automotive use as a result, and now, SK On has officially opened a plant dedicated specifically to that type of unit.

The new SK On solid-state pilot battery plant is now open in South Korea, a key step in the company’s plan to bring those next-generation batteries to market by 2029. It’s the culmination of combined research between that company and Solid Power over the past year or so, and at first, will be used as a pilot plant where prototype batteries will be built, assessed, and validated for quality and performance before full-scale production begins. SK On said its pilot plant will be primarily used to develop sulfide-based ASSBs, while some lines will be dedicated to lithium-metal batteries.

“This pilot plant will serve as a cornerstone for SK to leap forward as a strong and resilient company in addressing any changes in business environment,” said SK On CEO & President Seok-hee Lee. “We aim to remain at the forefront of commercializing all-solid-state batteries to accelerate electrification.” The company initially aims to commercialize ASSBs with an energy density of 800Wh/L, with a long-term goal of reaching 1,000Wh/L.

While Ford is heavily vested in solid-state batteries and views them as the future for EVs, in general, the automaker is also keeping an open mind in regard to battery chemistries. “Yeah, we’re always thinking about the next chemistry. I mean, I’ve been in this space for – since we started this journey for the last four years and we’ve already gone from a high nickel-based chemistry to a mid-nickel-based chemistry to an LFP chemistry to now we have LMR which is a manganese rich chemistry,” Ford Vice President Lisa Drake said at the recent 2025 Jefferies Industrials Conference.

I think we will hear much about SSBs in the next few years. When the cars hit the roads, that's when everything from production glitches and technology refinement will take place. I think China is also building plants. CATL and BYD may be a couple of years ahead of SK.

The next breakthrough will be huge. To have, for example, double the current range while towing would be a massive game changer for electric pickups. After 200 miles I'm ready for a break from driving anyway.
