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.

The next big #EnergyStorage device could be a 1000 °C #SandBattery
With high specific heat, low thermal conductivity, and no risk of fire, sand-based energy storage systems are gaining traction in grid-scale and industrial heating applications.
by Georgina Jedikovska, Jul 17, 2025
Excerpt: "While at first glance, sand might not seem like the most high-tech solution for energy storage, its ability to capture and retain heat has been harnessed for millennia.
"Sand might not seem high-tech, but its thermal properties have been used since antiquity. #AncientEgyptians mixed sand, silt, and straw to construct homes that absorbed solar heat by day and slowly released it by night.
"Today’s engineers are taking that principle further using refined materials, insulated steel silos, and precision heating systems to build high-temperature thermal energy reservoirs using sand."

How 2,000 Tons Of #Sand Stores 100 Megawatt-Hours And Slashes Carbon Emissions 70%
By John Koetsier, Apr 14, 2026,
"#PolarNight is doubling its size with a new 250 megawatt-hour facility in Vaaksy, #Finland, which will output 2 megawatts of energy consistently. That newer and bigger battery will use only slightly more sand – 2,400 tons – because the #SandBattery’s design renders it more efficient with size. What will become the new world’s largest sand battery is already under construction and is scheduled for completion in summer 2027."

4.5 GW / 11 GW of large-scale battery #EnergyStorage got added since the end of Q1 2025 and the impacts are real. Coal and gas shares declined.
The simple matter is that energy storage enables more #Solar and #Wind power deployment by preventing curtailment.

Okay it is a TEST (pardon the mess) but I can officially do charge/discharge tests on a much larger scale now! Should cover my needs for a while, can allegedly go up to 24 A/30 V/75 W (though not with this wiring setup, lol). Testing out automated charge/discharge testing as I mentioned in https://dualpower.supply/posts/lab-notebook-14/#large-cell-testing. It basically worked first try. Shout out to OSHW, this probably saves us thousands of euros on a commercial equivalent of similar precision. #EnergyStorage #Batteries #OpenScience #OpenSource

Ready to take charge: three innovative types of energy storage
-
With Underground Thermal #EnergyStorage, or simply "#Geothermal Storage", bulk quantities of hot or cold water gets stored underground with modest energy leakage.
A very salient use case is using #Solar powered heat pumps during summer to heat up water for geothermal storage. Then during winter, this hot water can be tapped to heat homes and #DistrictHeating networks. This is #SeasonalEnergyStorage for solar.
Renewable heat displaces gas.
