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.
Whether manufacturing or using lithium-ion batteries, anticipating and designing out workplace hazards early in a process adoption or a process change is one of the best ways to prevent injuries and illnesses.
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).
Safety issues may arise during the life cycle of primary lithium batteries due to any of the following processes: Highly flammable hydrogen gas is generated, usually followed by ignition, upon contact of lithium metal with water.
Do not overcharge batteries. Do not leave batteries connected to chargers after charging is complete. Proper lithium-ion battery storage is critical for maintaining optimum battery performance and reducing the fire and explosion risk.
In extreme cases, these defects may result in severe safety incidents, such as thermal runaway. Metal foreign matter is one of the main types of manufacturing defects, frequently causing internal short circuits in lithium-ion batteries. Among these, copper particles are the most common contaminants.
