In this post, we’ll delve into the potential dangers of lithium-ion batteries and how we can take steps to mitigate these risks and keep ourselves safe. What’s more, the fires resulting from lithium-ion batteries are notoriously difficult to extinguish because the battery essentially fuels itself. Toxic and Corrosive Materials: Lithium-ion batteries are filled with potentially toxic and corrosive materials. Overcharging and Overheating: Overcharging or charging at a temperature too high can severely damage lithium-ion batteries, increasing the risk of thermal runaway. Mind the Temperature: Lithium-ion batteries don’t fare well under high temperatures, so keep your devices away from direct sunlight or hot cars.
