Solid-State Battery Has 2x the Energy–and No Anode

I read an article somewhere that discusses how Toyota has the most battery patents out of any company and also owns most of the solid state patents and are actually working on commercializing solid state batteries for vehicles. The point I think the article was trying to make is that while everyone is focused on lithium ion, Toyota was biding it’s time and getting ready to one-up everyone with solid state batteries a…

Please share that article if you can find it. Sounds like an interesting take! I honestly don't get the criticism Toyota has been getting recently. I think their decision to not go all in on just electric vehicles makes sense, especially for countries where it is highly unlikely that full EV will be a reality in the next decade.

Nice, when can we use them for phones and laptops lasting 72% longer and without fire risk? Genuine question, because optimistic battery articles have been popping up for decades, but here we are still with lithium ion in practice.

> here we are still with lithium ion in practice Lithium ion batteries are actually amazing tech. I certainly remember the world without them; laptops had an hour of battery life, mobile phones were "car phones", everyone was running around paranoid about the "memory effect", and electric cars were an interesting curiosity always ten years away. Here we are today with pocket computers that last for days and electric…

Surprised how "dead" this industry is. I remember having Lithium-Ion batteries since I was in high school which was more than 20 years ago (and some Li-Po until then). Everything is leaps and bounds since then but not the batteries. Seems like a massive disconnect to me but I'm no chemist or researcher in this field.

Energy density is ~8 times higher than in 2008 at 1/10th the price. That's more progress than we've made in single-core performance in the same timeframe.

Why is it called anode-free when it still has a copper collector with a special coating? Yes, they removed the graphite, but they didn’t remote the entire “anode”. Or is it because the collector and the coating are not technically considered as an electrode?

I initially thought this was an early April Fool's joke in a different time zone to me. It does sound to me like they're replacing the traditional anode with a different anode.
