The battery miracle online is doing the most
All-solid-state battery diagram by Luca Bertoli, CC BY-SA 4.0, via Wikimedia Commons.Dear Cherubs, the internet has once again discovered a battery so perfect it sounds like it came from a pitch deck written by a caffeinated intern and approved by gravity itself. The specific 90-second charge, 99.7% storage retention, and 5,000-cycle package circulating online was not verifiable from primary sources I checked, so the smart move is to treat it as a viral claim, not a finished breakthrough.
Reality check
What is real is the bigger trend: solid-state batteries replace the flammable liquid electrolyte used in conventional lithium-ion cells with a solid ion conductor, which can improve safety and potentially raise energy density. MIT has been making that case for years, while also pointing out that the interface between materials is still the part where the dream gets stuck in traffic.
That interface problem is not a footnote. MIT’s recent coverage says solid-state cells are still plagued by dendrites that can short-circuit the battery, and a 2020 MIT review lays out the rest of the mess: chemical stability, mechanical stability, processing, and long-term performance. In other words, the field is advancing, just not in the magical “plug in for 90 seconds and disappear for six months” way social media likes to sell it.
DOE’s battery overview says solid-state batteries can be safer because they are less prone to leakage from damage or swelling in hot temperatures, but it also notes that some designs still use a little liquid at the cathode to reduce interfacial resistance. Translation: progress, yes. Fairy dust, no.
Why it matters
The good news is that the field is moving. In 2025, Stellantis and Factorial Energy said they validated automotive-sized solid-state cells with 375 Wh/kg energy density and fast charging from 15% to 90% in 18 minutes, with a demonstration fleet planned for 2026. That is not “two-minute EV charging,” but it is a serious step forward, which is how real engineering usually behaves when nobody is trying to go viral.
So the right takeaway is not that battery problems have been solved. It is that researchers keep making the hard part less impossible. If the viral post was pointing at a real advance, it was probably one brick in a wall, not the wall itself. The upside is still huge: safer packs, longer life, and faster charging. The downside is that physics remains deeply committed to being inconvenient.

#BurlingtonVT startup #NthCycle scores billion-dollar metal #recycling deal
By Hiawatha Bray Globe Staff, March 17, 2026
"Both Nth Cycle and Ascend have developed water-based technologies to extract metals by reprocessing 'black mass,' the ground-up remnants of worn-out #lithiumIon batteries. They can also use the leftover scrap generated by battery manufacturers. Both companies claim that their technologies can capture these metals while generating far less #ToxicWaste than other recycling methods."

For when I'm working on something containing an energetic battery.
(Inspired by Big Clive, obviously)

Like seriously. It's so light I feel like I'm not even holding anything. Like I know I have that shitty battery on my palm but it might as well just be air ! We don't have a kitchen scale but I'm guessing it weighs more or less as an empty small milk carton
I remember watching Adam Savage's vid about lithium ion batteries. Oh hey I just realized he's holding the vapcell battery I'm using on my fan right now lol

#Maine will require battery makers to provide #recycling options
By Tina Fischer, April 9, 2026
"Gov. #JanetMills signed into law a measure that will offer more options to recycle both single-use #alkaline and #LithiumIon batteries in Maine.
"LD 474 updates the state’s current product stewardship laws to require national battery manufacturing companies to set up drop-off locations and fund a statewide take-back program so that all batteries can be safely disposed of and rare earth metals can be extracted for reuse.
"Eight other states have enacted similar laws.
"The state’s existing battery recovery program, enacted in 1991, covers only nickel-cadmium batteries. Many hardware stores, town offices and Staples stores in Maine accept some types of batteries for recycling. The nationwide Battery Network lists on its website drop-off locations in Maine.
"Improper disposal of lithium-ion batteries — commonly found in power tools, cell phone chargers and #vaping devices — has led to at least 24 fires at recycling facilities in Maine. Disposal concerns have driven up insurance rates for towns, according to the #MaineDEP.
"More than 820,000 pounds of batteries are thrown away in Maine every year, according to the Natural Resources Council of Maine [#NRCM].
" 'Holding corporate battery makers accountable for cleaning up waste will lower costs for Mainers and help curb demand for mining rare earth metals,' said Vanessa Berry, sustainable Maine program manager at the nonprofit.
"It is technically illegal in Maine to dispose of rechargeable, button cell, or lead-acid batteries in the regular trash."

Someone should create a #LithiumIon charging tray, where if the device you are charging catches on fire, it will melt through a barrier and drop into some heat absorbing medium.

What’s flying under the radar in this energy crisis is storage—grid + home (#BESS + #BTM). #Lithium-ion deployments surged ~60% in 2025. Shocks used to trigger more supply. Now they accelerate demand destruction. The oil addiction cycle is breaking in real time. #Bettrification

I've started exploring and learning about rechargeable batteries as a hobby for a few days now and I've spent more than a hundred dollars. That's why I haven't been posting lately
I've bought pretty much the same thing that's on this video lol. Definitely not cheap. I could've bought RE 9 but I chose to spend some money starting out.
If anyone's got experiences with this, pls share. Thanks

I have posted about this before, but seriously, what sort of magic sauce is in these cells in this pack?
After sitting on a shelf all winter long, this 9 1/2 year old battery mowed my entire 3000 ft.² front yard of overgrown spring weeds and still had power left when I was done.

I recently found my old power bank which I bought in early 2018ish…. It was functional and I checked it’s state of charge, it was running low so started reconditioning it for use. After a month of infrequent use the battery has swelled up and the case has literally flexed and deformed.
Thankfully I saw it when it was already at a lower state of charge and quickly removed it from my desk and safely discharged it on a low current load.

The falling prices of Lithium-ion battery cells.
To transition towards low-carbon energy systems, we need *low-cost* energy storage. Lithium-ion batteries are the most commonly used.
The prices of these lithium-ion cells have fallen by more than 99% since 1991.

I’ve worked in fire safety management and training for 28 years. In that time, one hazard has grown from niche to everyday risk: lithium-ion battery fires. These incidents don’t behave like “normal” fires — and that difference is critical for safety. 🧵

FFS, how many times does it have to be said? DO NOT use Lithium Ion for static installations. They don't need the energy density and we don't need the fire risk.
LiFePO₄ is cheaper, inherently less risky and available in grid scale quantity.
Sodium is likely to be even better in some respect.

RE: https://mastodon.social/@ieeespectrum/115583916468218862
The article says that they've designed the battery system to prevent thermal runaway, i.e. a fire 🔥, and to contain it if one does occur, but I would feel very anxious on boarding this ship.

New company on #BayFarm island in #EastBay says they have created the “#NextGeneration” of #batteries that are safer than explosion prone #lithiumIon types and will revolutionize industries from small portable devices to #ElectricVehicles.
Many new #batteries use a liquid #lithium-ion core that can leak and combust, while #Alameda based #AnthroEnergy’s solid-state batteries use a patented technology to solidify the core. The developer claims the innovative tech creates a non-flammable, semi-solid battery with 35% more energy density than traditional batteries, and is resistant to leaking, warping and combustion.
They hope to get more investment into their #BayArea plant and begin production of half a million individual battery cells a year.
