Large-scale testing has shown that lithium- ion batteries behave similarly to unexpanded plastic commodities in a fire


batteries in storage are not typically subject to internal ignition. However, large-scale testing has shown that lithium-ion batteries behave similarly to unexpanded plastic commodities in a fire. Therefore, sprinkler protection should be provided. Fully charged lithium-ion batteries


have a higher energy density and are therefore at greater risk of generating significant heat from short circuiting caused by internal defects. Be mindful of the manufacturer’s recommended temperature and ideal charge level for storage as they can differ by chemistry and battery type. While usually safe, as lithium-ion


battery charging can cause safety problems, stations designated for charging large format batteries should be separated from other combustible materials by at least one metre. For larger format batteries, such as those used in mobile equipment, battery chargers and batteries being charged should be separated from other combustible contents by at least one metre. Stations used for charging small format batteries should be set on a firm, non-combustible surface and be separated from other combustible materials by at least 30 centimetres. Before disposing of damaged or


unwanted lithium-ion batteries, in waste bins for example, their battery terminals should be covered with insulating material. Tis will help to ensure that the terminals do not accidentally come in contact with metal or other battery contacts that could close the battery circuit and result in an unintended energy discharge. Likewise, bins holding damaged or discarded batteries should be separated

by at least three metres from all other storage areas, as well as bins holding other potentially combustible materials. Tis separation will help to reduce the risk of spreading a fire that might originate amongst discarded or waste batteries. In addition, these bins should be metal and have metal lids whenever practical. Internal components and mechanisms


in lithium-ion batteries are highly susceptible to physical or mechanical damage when the battery is subject to a severe external force or when it is dropped on a hard surface. Any external evidence of damage should therefore trigger concerns about a battery’s internal integrity, and it should be safely disposed of in bins intended solely for damaged batteries. For larger format batteries, such as


mobile equipment batteries, ensure that battery chargers and batteries being charged are separated from other combustible contents by at least three metres. As lithium-ion batteries bring so


many positive benefits to industrial innovation, they will continue to evolve as manufacturers seek new ways to increase battery density and reduce size. Terefore, the safety of lithium-ion battery technology will continue to be investigated to address unexpected hazards that emerge. As we learn more about the risks associated with the use, bulk storage and recycling of lithium-ion batteries, changes in standards and best practices can be expected to change as well. It is therefore vital that the safety of lithium-ion battery technology and its storage remains under scrutiny so that these evolving hazards can be addressed. As there are hazards specific to


lithium-ion battery storage in industrial and commercial environments, the proper storage and risk management of lithium-ion batteries is critical. Tere are fundamental strategies that can be implemented to reduce the potential risks associated with battery-related fires and explosions. It is certain that proper storage and risk management are critical in avoiding battery malfunctions.
