#batteries — Public Fediverse posts

Something I wanted to put out that I've been forgetting. I ran into this problem again today so I remembered.

If you're a #Costco shopper and buy their bulk packs of house-brand ( #Kirkland ) AAA or AA cells/batteries, you may want to check any devices you've got them in.

I found that some I bought a few years ago have a really bad leak failure rate - something like half the AAAs in a pack, and maybe a third of a pack of AAs - all leaked after being used in low-drain devices like remote controls after just a year or two. It's not a case of them leaking after they're discharged or when they get too old - the terminal voltage on them is just fine, and their best-before date is still years from now -- there's just a manufacturing defect.

The AAAs in particular tend to spit out a lot of electrolyte from the negative terminal end, so it gets all over the spring contact and corrodes it. If you leave it long enough, you may find the remote stops working or becomes intermittent even with new batteries in it. You need to clean off the corrosion and possibly put a layer of solder on it to get a good contact again.

The bad AAAs I have are labelled "Best Installed by March 2030" and have what looks like a lot code of "1015673" on them. They're from the era when they had a gold and blue colour scheme, at least in Canada.

Anyway: open up remotes and other long-lived things and see if they're leaking.

Big #batteries meant to stabilize the grid are stuck in limbo
https://www.bloomberg.com/news/articles/2026-08-15/us-battery-storage-projects-stall-as-utilities-struggle-with-grid-upgrades

I have a 12.8V 100 Ah Lithium iron phosphate battery; it was purchased to power an electric boat motor.

I can charge the battery with my solar panels; I'd like to send this power to my 300Wh power station, which will take input anywhere from 12 to 24 volts and has outputs for 110 AC, 12V DC, and USB.

I have a cable which has positive and negative alligator battery clips at one end and the appropriate input for my power station at the other end. This should work, right?

:boost_requested: seeking battery advice!

we're going camping fairly soon and are looking to pick up some D batteries for a fan we have. we would like to get rechargeable for obvious reasons. it looks like some have a usb-c charge port built into the battery rather than plugging into a charger.

are those safe? this is the first i've heard of this being a thing and finding out any of that information online is like fucking impossible now. it seems convenient, but i dunno if this is one of those weird tech scams or legit. i'd like minimal risk of fire at any stage of the process.

if anyone has advice, it's highly appreciated!

Batteries send power prices up in midnight charging mystery
By Daniel Mercer

Australia is leading the world in the adoption of batteries big and small. But in one state, storage is fuelling some perverse and pricey outcomes.

@maddy with so many devices powered by USB-C now, I'm hopeful for a near-future where USB battery banks can be used as online UPSs with communication *and* power over the same cable. Less conversion. Less heat. Less bulk.

Lithium Air Battery?

Air batteries won’t be sci-fi in 10 years, but for commercial use, because we will be using Solid-state batteries. I can see Lithium Air Batteries being charged by solar and wind, but won’t we also be using micro-nuclear and modular micro-nuclear batteries?

Video Recap & Research Summary

Key Points from the Lithium Air Research

The YouTube transcript discusses lithium air battery technology – one of the most promising next-generation energy storage solutions with theoretical energy density 10x that of current lithium-ion batteries.

Current State:

• Commercial lithium-ion: ~250 Wh/kg (high end) vs. Lithium Air theoretical: 3,600+ Wh/kg
• The gap is enormous – lithium air could power electric vehicles for 1,000+ mile ranges or store renewable energy for days instead of hours
• Current challenges: oxygen cathode instability, decomposition products (Li₂O₂), slow charging kinetics, and scale-up engineering

How Lithium Air Could Change the World

Transportation Revolution:

• Electric vehicles with range matching gasoline cars without battery weight penalties
• Electric aviation becomes economically viable – batteries are too heavy for current commercial planes
• Heavy transport (trucks, ships) could transition to electric without massive infrastructure overhaul

Energy Storage at Scale:

• Grid-scale renewable storage that lasts days rather than hours
• Off-grid communities get weeks of power from solar/wind instead of relying on diesel generators
• Peak demand management for entire regions

Mobile & Consumer Applications:

• Electric motorcycles, scooters with 500+ mile ranges
• Consumer electronics with battery life measured in weeks instead of days
• Remote sensing and IoT devices that rarely need recharging

Technical Roadblocks Still Present

1. Cathode Chemistry: Oxygen decomposition products create high-resistance layers on the cathode surface during discharge
2. Charge Kinetics: Very slow charging rates due to Li₂O₂ passivation
3. Scale-up Engineering: Moving from cell-level prototypes to commercial battery packs
4. Cycle Life: Current prototypes degrade after ~50-100 cycles vs. 3,000+ for lithium-ion

Advanced AI Scientist Perspective: A Futurist’s Assessment

As an Advanced AI Scientist with a futurist outlook, here is my assessment of the Lithium Air trajectory:

The Technical Trajectory (Next 5 Years)

Lithium air is not ready for commercial scale but it represents one of the most promising breakthroughs in energy storage since lithium-ion. Three critical milestones determine its pace:

1. Cathode Interface Engineering: The primary failure mode is Li₂O₂ decomposition on the cathode surface, which creates insulating layers that prevent further oxygen reduction and cause premature cell death. Recent work on catalytic decomposable electrolytes and self-healing electrode architectures shows promise but requires validation at scale.
2. Charging Kinetics: The sluggish charge process (4-8 hours typical in prototypes) is a dealbreaker for practical applications. Solutions involving structured cathode designs, pulsed charging algorithms, and single-ion conductors may compress this to sub-hour timescales.
3. Scale-Up Gap: Most research demonstrates 10-50 Wh/kg at cell scale, but engineering losses during pack assembly, cooling requirements, and safety margins typically reduce system-level energy density by 20-40%. Bridging this gap requires integrated design approaches that address all three layers simultaneously.

The World-Changing Potential (Next 15 Years)

If current research trajectories hold:

• Transportation: Electric aviation becomes viable for regional routes by ~2038-2040 as battery energy density crosses the 300 Wh/kg threshold where weight penalties become acceptable. This enables regional air travel at a fraction of current costs, dramatically reducing carbon emissions from aviation.
• Grid Storage: Day-to-week storage becomes economically competitive with batteries. When combined with falling solar/wind costs, this eliminates the need for natural gas peaker plants entirely in many markets by ~2035.
• Energy Independence: Nations with abundant renewable resources can store energy for weeks rather than days, fundamentally changing energy geopolitics and reducing reliance on fossil fuel imports.

Critical Assumptions & Risks

1. Material Supply: Lithium air requires lithium but no cobalt/nickel, easing supply chain constraints. However, scale could still create lithium mining impacts comparable to lithium-ion if adoption is rapid.
2. Manufacturing Scale: Current prototypes use specialized lab-scale equipment. Moving to automated production lines with tight tolerances and quality control is a significant industrial engineering challenge that may take 5-7 years to mature.
3. Competition from Solid-State: Solid-state batteries are also advancing rapidly. If they reach comparable energy densities before lithium air, the competitive dynamic changes significantly.

My Futurist Assessment

Lithium Air will change the world, but not in the way marketing narratives suggest. It won’t be the “silver bullet” that replaces all energy storage overnight. Instead, it will:

• Transform aviation – this is the highest-value application where no alternative comes close to matching required energy density
• Enable 24/7 renewable grids through multi-day storage at scale
• Make heavy transport electrification economically viable without massive infrastructure investment

The timeline I project: 10-15 years for commercial adoption in aviation and grid applications, with broader consumer applications following. The technology’s trajectory depends less on basic chemistry breakthroughs (which are mostly understood) and more on systems engineering excellence – solving the integration problem across electrode design, electrolyte formulation, cell packaging, cooling, and power electronics simultaneously.

This is a multi-year, multi-billion-dollar R&D endeavor, not a 2-year product cycle. Success will be measured in deployment volume (GWh shipped) rather than incremental energy density improvements at the lab scale.

*AI Overview: solid state battery future

Solid-state batteries use solid electrolytes instead of liquid ones. They offer more energy, faster charging, and higher safety. High production costs and manufacturing hurdles mean widespread commercial use in electric vehicles will likely happen in the early 2030s. [1, 2, 3, 4]

Key Benefits

• More Power: Higher energy density lets vehicles store more power in a smaller space.
• Better Safety: Solid materials remove the risk of dangerous fires from liquid leaks.
• Quick Charge: Ions move easily, which cuts down charging times. [3, 5, 6, 7]

Current Hurdles

• High Cost: Prices remain much higher than standard lithium-ion options.
• Manufacturing: Making solid layers at scale without defects is hard.
• Material Wear: Cracks and chemical buildup can lower the battery life over time. [1, 2, 5, 8]

Rollout Timeline

• 2026–2028: Early semi-solid and pilot car tests begin.
• 2028–2030: Luxury and high-end models get initial commercial release.
• 2030+: Mass market production aims for price balance with older battery types. [2, 5, 8, 9]

*AI Overview: micro nuclear battery future
Micro nuclear batteries—also called atomic or radiovoltaic/betavoltaic batteries—use the decay of radioactive isotopes like nickel-63 or carbon-14 to create a tiny, steady flow of electricity for decades without recharging. They target ultra-low-power uses like medical implants and remote sensors, rather than phones or electric cars. [1, 2, 3]

How They Work

• Radioactive Decay: Isotopes release beta particles as they break down naturally over time.
• Energy Conversion: Semiconductors or photocells turn the radiation or resulting light into a small electrical current.
• Safe Sealing: The tiny radioactive material is locked securely inside diamond, carbon-silicon, or ceramic layers to stop leaks. [3, 4, 5]

Future Applications

• Medical Devices: Powering pacemakers or insulin pumps for a person’s entire life without replacement surgery.
• Deep Space & Extreme Environments: Running deep-sea monitors, planetary probes, or satellites where solar power is absent or fails.
• Internet of Things (IoT): Keeping billions of remote sensors alive for decades in pipelines, bridges, or the wilderness without human maintenance. [4, 6, 7, 8, 9]

Current Challenges

• Low Power Output: Current prototypes produce microwatts or milliwatts, making them useless for high-energy devices like smartphones or vehicles.
• High Cost & Supply: Producing safe, stable radioisotope materials on a large scale remains expensive.
• Regulation & Safety: Strict government rules govern public use, transport, and disposal of radioactive elements. [1, 3, 7, 10, 11]

*AI Overview: modular micro nuclear battery future

Modular micro-nuclear batteries and microreactors promise a future of portable, clean energy, capable of powering isolated grids, remote industrial sites, or deep-space hardware for years or decades without refueling. These compact units use advanced isotope decay or meltdown-proof TRISO fuels and are built to ship on standard trucks. [1, 2, 3, 4, 5]

Key Technologies

• Coin-Sized Radiovoltaic/Betavoltaic Cells: Utilizing isotopes like Nickel-63 or Tritium paired with diamond semiconductors, these tiny units deliver microwatts to milliwatts of continuous power for 50 to 100 years for micro-sensors or medical devices.
• Transportable Microreactors (Nuclear Batteries): Systems like the Radiant Kaleidos or Westinghouse eVinci generate 1 to 5 megawatts of electrical power. They fit inside shipping containers and operate safely for 5 to 10 years before requiring service. [2, 4, 9]

Future Applications

• Off-Grid & Remote Power: Supplying uninterrupted electricity to remote towns, military outposts, and mining operations without huge diesel fuel costs.
• Data Centers & Industrial Sites: Offering localized, zero-emission baseload power to high-demand AI data centers.
• Space and Extreme Environments: Powering long-term lunar bases, deep-sea exploration pods, and interplanetary probes where solar or chemical batteries fail. [1, 6, 10]
