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.
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.
In this review, we analyzed the main causes of the safety risks of LIBs and examined the inherent electrochemical mechanisms of LIBs. We also summarized the main factors that affect the safety of on-board LIBs, including battery materials, design, abuse conditions, and battery status.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
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).
Hazards involved in these process steps include: Material handling of charged lithium-ion cells (conveyors, stacker cranes, automated loading/unloading of trays of cells, removal of gas buildup during the Degas stage, Automated Storage and Retrieval Systems). Charging and discharging of lithium-ion cells.
