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
Intact Lithium-ion batteries are considered to be Universal Waste (i.e. a subset of the hazardous waste regulations intended to ease the burden of disposal and promote the proper collection, storage, and recycling of certain materials). Damaged Lithium-ion batteries are considered to be Hazardous Waste and must be collected through the EHS Office.
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.
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.
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).
In addition, due to lithium electroplating, the pores of the negative electrode material are blocked and the internal resistance increases, which severely limits the transmission of lithium ions, and the generation of lithium dendrites can cause short circuits in the battery and cause TR [ 224 ].
Lithium Ion Battery
Possible causes of lithium-ion battery fires include: over charging or discharging, unbalanced cells, excessive current discharge, short circuits, physical damage, excessively hot storage and, for multiple cells in a pack, poor electrical connections. Always purchase batteries from a reputable manufacturer or supplier.
