Here’s Why Lithium Batteries Occasionally Just Catch Fire

Li batteries are compact , effective , and hive away a lot of muscularity . They also , occasionally , catch on fire . Here ’s how that happens .

The dandy affair about lithium batteries is they keep store a vast amount of energy in a small , light package . This makes them perfect for use in planes , cars and laptop computer . The bad thing about lithium batteries is they have a huge amount of vim on tap , and it can be free in a very diminished space . This make them terrible for use in plane , cars , and laptop .

engineer overcome the sorry side of atomic number 3 batteries through careful design , and manufacturer overcome it through timber control . That does n’t have in mind thing ca n’t from time to time go wrong . basically , when you charge a Li battery , you bone electron into a carbon copy storage unit . You tap that energy by permit the electron flow through an electrolyte full of atomic number 3 salts . ordinarily the stream of electrons is regulated . An article in The Economist explains what happens when things go big .

The difficulty come about if there is a small break or damage is induce to the passing thin separators that keep the elements of the battery apart . This can lead to an internal short - circuit and a subsequent build - up of heat . This can activate what is get laid as a “ thermal runaway ” in which the barrage fire overheats and can abound into flame . That can cause adjacent battery cells to overheat , which is why groups of cells in some battery packs ( such as those used in Tesla cars ) are kept in separate protective compartments .

These things rarely happen , and when they do , for the most part they result in piddling damage . So far , though , there ’s no means to get around the trade off . A lot of vigor on spigot think a little more risk that it can get out of hand .
