New Power Banks Released By BMX With Safer Semi-Solid-State Batteries (androidauthority.com) 23
From Android Authority:
Singapore-based BMX has announced that its SolidSafe magnetic power bank lineup, first showcased at CES 2026, is now available for purchase through its website and Amazon US, with prices starting at $59. What sets these power banks apart is their use of semi-solid-state batteries. Traditional lithium-ion and lithium-polymer batteries rely on liquid electrolytes to move energy between electrodes. Semi-solid-state batteries significantly reduce the amount of flammable liquid inside the cell, improving thermal stability and lowering the risk of overheating, swelling, or fire...
BMX says the power banks are designed to remain stable under extreme conditions and show greater resistance to physical damage and thermal stress than conventional battery packs. The company has also launched the SolidSafe Air, a 5,000mAh magnetic power bank that it claims is the world's thinnest semi-solid-state Qi2 power bank... BMX is positioning the device as a travel-friendly alternative for users who want added safety and the convenience of a magnetic battery pack without the bulk.

Solid state is finally going mainstream, I like it!

and every one of them comes with an entire list of things you're not supposed to do if you don't want it catching fire.
don't puncture it. don't crush it. don't bend it. don't overcharge it. don't leave it in the heat. don't use a damaged charger. do

The thing that amazes me is that we haven't seen any plane crashes. Looking at a video of thermal runaway of even a small battery, I absolutely don't want that happening on a plane.
And there aren't even any hard limits to what you can put in checked luggage, as far as I can tell. Only guidelines.

There have been plane crashes or emergency landings due to lithium battery fires. That's why the rules about safe transport of lithium batteries were introduced.

There's been no shortage of incidents, but have any passenger planes actually crashed?

Not a crash, but the plane was destroyed before take-off: https://ctif.org/news/lithium-... [ctif.org]

The whole selling point of solid-electrolyte lithium batteries is that the don't burst into flames if used wrong.

It's not solid-state, it's pseudo-solid-state, also known as marketing-solid-state.
Unfortunately the web site doesn't specify which of the pseudo-solid-state technologies it uses.

Saying that implies that just because it isn't 100% free of fluid means there aren't benefits to it. That is completely disingenuous of you. Just because they use semi-solid-state (their words on their website) doesn't mean they aren't using a battery which meets many of the benefits of solid state batteries.
There's nothing "marketing" about this. They are using an alternate and safer chemistry, different from traditional lithium battery packs.

I noticed that too. This is likely Li-Ion with some claims as to better safety. Which may simply be lies. Would not be the first time.
Re: (Score:2)
It's also not inherently safer. The problem with current Li-Ion isn't the chemistry - it's the charge density. That's why a discharged spicy pillow isn't. You can stab both a charged and a discharged battery, and only the charged one will catch fire. The discharged one does absolutely nothing.
The breakpoint is around 50% - below that and they're rather tame. Above that and they get spicy.
If the battery technology offers an equivalent charge density, well, it'll have the same problems. Storing that much ener

I think it's fantastic that they are reducing the amount of hot sauce they are putting in batteries but I think they need to push until they completely eliminate it.
A slow burn is better but no-burn is best.

Have you ever punctured a lipo cell? I have. Nothing happened. Then I put it in water. There were a few little bubbles. Over the next two years the pack gradually grew until it was about three times its prior size, and hard. At no time did it emit flames. (I kept it in a coffee can.)
I think NCM batteries in particular are fucking terrible and I don't want to downplay that there is a risk of thermal runaway for all lithium cells with liquid (etc) electrolyte, but overstating the case is not a help.
Re: (Score:2)
The risk is when it has a full charge and has this happen. More of these batteries (Specifically Li-Poly) set fire due to damage (First) followed by the resistance and heat from incoming power (charging).
The damage (drops, crushing, too high of operating temps) causes layers to seperate, causing more resistance to any process, and then something stresses it (charging). this is is how you get spicy pillows. Li-Poly will also not rupture, if there's no energy to go out of control. It's similar to nuclear m

The problem is improperly managed (damage/overcharge/etc) cells self-inflate to become what what the internet refers to as a spicy pillow [powerbankexpert.com]. If they have eliminated the possibility of creating a spicy pillow then I have overstated the danger. However, so long as battery damage results in thermal runaway that causes a total carbecue then it they need to keep pushing toward making it entirely solid-state. ICE has a higher chance of carbecues but facts be damned, people are sufficiently stupid to hold onto that
