Theoretically, batteries can use water as the solvent, but they usually don’t. Part of that optimization is in the liquid electrolyte: standard lithium-based batteries use organic solvents mixed with salts to shuttle charge around. Lithium-ion chemistry has been optimized over decades to pack a lot of energy into a small, lightweight device and deliver a lot of power. But some battery makers want to build alternatives that can’t catch fire in the first place. It doesn’t happen often, and there are many, many safety controls that can be put in place to manage the risk effectively. What it comes down to is this: lithium-ion batteries can catch fire. These fires, which can be deadly, have mostly been caused by bikes that aren’t repaired correctly or use substandard batteries, highlighting the need for regulation and tight quality control of batteries. There’s also growing concern about fires started by e-bikes in New York City. But a string of fires doesn’t look too great. No injuries were reported in any of the fires, and damage was mostly limited to the batteries themselves. As Canary Media reported, New York has seen a few battery fires this summer in large-scale stationary storage installations on the grid. These storage systems are great news for cutting emissions, but things can go wrong with them as well. As we install more renewable energy on the grid, there’s a growing need for large-scale energy storage installations that can save solar power for use at night, for instance. The question of safety could become an even more important one as we start to use batteries in a new way: on the power grid. ![]() But on the other hand, EV fires can burn hotter than fires in conventional cars, and they are harder to put out. It’s not totally clear how often EVs catch fire in general, though some data suggests it’s much less often than gas-powered vehicles. Manufacturing defects happen ( remember those Chevy Bolt fires?). Devices that use lithium-ion batteries typically have safety systems in place to manage this risk: electric vehicles have cooling systems installed around battery packs, for example.īut sometimes things can go wrong. Lithium-ion batteries can and sometimes do catch fire, usually when they’re damaged or when they get too hot, kicking off chemical reactions in a process called thermal runaway.
