Battery manufacturers put a lot of safeguards in place to prevent batteries failing, or at least mitigate the damage a failure can cause. The fact that it’s always news when a battery explodes unexpectedly shows how rare an event those big failures are.
Once one cell overheats, you get a domino effect called “thermal runaway.” For batteries with hundreds of cells-like those in the Tesla Model S-thermal runaway has the potential to be a really big problem.Įven though examining why battery sometimes fail paints a frightening picture, lithium-ion batteries are a safe and mature technology.
There are a number of reasons that the separator can fail: And once those two get together, the battery starts to overheat. This happens when the plastic separator fails and lets the anode and cathode touch. Most lithium-ion battery fires and explosions come down to a problem of short circuiting. This lithium-ion battery from a Japan Airlines Boeing 787 caught fire in 2013. When it’s released all in one go, the battery can explode. When it’s released as a trickle, it powers your phone all day. Lithium is really great at storing energy.
The very thing that makes lithium-ion batteries so useful is what also gives them the capacity to catch fire or explode. What Makes a Lithium-Ion Battery Explode? The batteries in electric cars and airplanes can have hundreds of cells. Larger batteries, like those in laptops, normally have between 6 and 12 lithium-ion cells. Small batteries, like those found in smartphones, usually have only a single lithium-ion cell.
