Video: Battery Explosion from the Inside
9 years ago, PC Pitstop first sponsored research regarding the volatility of lithium ion batteries found in laptop batteries. Unfortunately, the need for this research continues in 2015 and Nature Communications has published a lengthy study including a fascinating look inside an exploding battery (see video below).
This is what a lithium ion battery looks like when it’s purposely heated to the point of explosion—for science. Sorry to dash any young pyromaniacs’ hopes, but it’s not something to try at home: Aside from the obvious dangers of exploding white-hot metal and chemicals, you’d need a synchrotron particle accelerator and a heat gun to pull off a vid like this.
For a new paper in Nature Communications, a group of UK and European researchers pushed two different commercial lithium ion batteries—which are commonly used in everything from smartphones to electric cars—to their breaking point, so they could observe what happens on the inside when they fatally overheat.
“Increasingly we’re pushing lithium ion batteries into a greater and greater range of applications,” said Paul Shearing, a chemical engineer at University College London and one of the paper’s authors, in a phone call. “But actually, the kind of underlying chemistry and the underlying engineering design of these things hasn’t changed enormously from when they were commercialised in the late 80s and early 90s.”
