Despite protection by battery safety mechanisms, fires originating from primary lithium and lithium-ion batteries are a relatively frequent occurrence. This paper reviews the hazards associated with primary lithium and lithium-ion cells, with an emphasis on the role played by chemistry at individual cell level.
Although definitive evidence on the actual mechanism initiating the events is often lacking, incidents can at times be linked to incorrect handling, storage and packaging practices that may lead to mechanical damage, water ingress, and/or internal or external short-circuit of charged batteries. 2. Hazards associated with primary lithium cells
Lithium battery fires and accidents are on the rise and present risks that can be mitigated if the technology is well understood. This paper provides information to help prevent fire, injury and loss of intellectual and other property. Lithium batteries have higher energy densities than legacy batteries (up to 100 times higher).
Lithium-ion batteries operating outside the safe envelope can also lead to formation of lithium metal and thermal runaway. Despite protection by battery safety mechanisms, fires originating from primary lithium and lithium-ion batteries are a relatively frequent occurrence.
Lithium batteries are highly flammable and can catch fire or explode if not handled properly. This risk is especially high during the manufacturing process, as the batteries are often exposed to high temperatures, charging variances and pressure.
Hazards associated with lithium-ion cells can originate from to the following side reactions: Molten lithium can form in the event of overcharging metal lithium cells due to the low melting point of lithium metal (180 °C).
