Sometimes, when a Li-ion battery gets damaged . lithium-ion fires can . While EVs are less likely to catch fire than cars with internal combustion engines, when they do, it's worse. The main cause of lithium-ion battery fire is the thermal runaway of the battery. "Batteries are optimised so that you don't charge too fast - if you do that you will plate the lithium." This is also why battery charging can be a frustratingly slow experience, she added. Lithium batteries have been problematic because . Let's find out. In general, lithium iron phosphate batteries do not explode or ignite. Hoverboards have been burning up because of problems with their lithium-ion batteries. Here's how that happens. Instead of using conventional, heavy positive electrodes, a lithium-air battery uses an oxygen and lithium reaction to produce current flow. Lithium ion battery packs are small and light and of the highest quality available, so they're popular with the electronics industry. The main culprit behind hoverboards catching fire is the lithium-ion battery pack. Advertisement. Though most lithium-ion batteries work fine, some over the past several years have caused explosions and fires that have resulted in property damage and personal injuries, including serious burns.
