By 2025, the global lithium-ion (Li-ion) battery market is expected to reach USD 100.4 billion, over 50% of which will be used for the automotive market.

Lithium-ion cells are popular because they allow large amounts of energy to be squeezed into a very small volume, which means one can extract energy faster than any other battery. Imagine you had a very small bottle of water but a very large straw to drink it with!

Although the benefit does not necessarily warrant them to be risk-free. Li-ion cells are extremely sensitive to high temperatures and inherently flammable. To understand how li-ion cells potentially cause harm and to avoid widespread damage, we need to dig into the science of battery technology.
