There will always be a realy fucking bad failure mode attached to any energy dense storage medium.
This is basic physics. The diffrence between a roaring fire in the wood stove, your car engine, an ultra high tech rocket motor and a bomb, is only the speed of the "flame front"
A battery has the same issues, in that the higher the energy density and the greater the expected rate of energy transfer, the greater the chance of
finding a way to detonate all the energy at once, which is actualy possible ,with a wood stove, if things go exactly wrong.Exceptionaly large explosions have happened with nothing more than dust, or flour.
4 things, you can pick 3.
fast, powerfull, cheap, safe.
- justlikereddit 1y agoA Lithium iron phosphate battery is significantly more stable and less likely to go thermal runaway in a fireshow-like fashion. The battery chemistry is important for this.
- jandrese 1y agoYes, but this article is mostly talking about TEMU or Amazon fly-by-night brand batteries, so you have to take their word that they are using Lipo4 cells and not just blatantly lying like they do for every other aspect of the product.
- joecool1029 1y agoThere are lithium ion chemistries that are less likely to thermal runaway, LMO (Lithium Manganese Oxide) is used in power tools and they don't seem to go up. Tradeoff is lower capacity.
