This thermal runaway can propagate to other batteries or combustible materials nearby, potentially resulting in large scale thermal events with severe consequences. Additional, although infrequent, events can result in lithium cells and batteries experiencing thermal runaway, a chain reaction leading to a violent release of stored energy and flammable gas. Once ignited, lithium cell and battery fires can be difficult to extinguish. They can overheat and ignite under certain conditions, such as a short circuit, physical damage, improper design, or assembly. Unlike standard alkaline batteries, most lithium batteries manufactured today contain a flammable electrolyte and have an incredibly high energy density. Lithium cells and batteries can present both chemical (e.g., corrosive or flammable electrolytes) and electrical hazards. The risks posed by lithium cells and batteries are generally a function of type, size, and chemistry. Why are Lithium Batteries Regulated in Transportation? Lithium batteries must conform to all applicable HMR requirements when offered for transportation or transported by air, highway, rail, or water.

The HMR apply to any material DOT determines can pose an unreasonable risk to health, safety, and property when transported in commerce. Department of Transportation's (DOT) Hazardous Materials Regulations (HMR 49 C.F.R., Parts 171-180). Lithium batteries are regulated as a hazardous material under the U.S. Shippers play an important role in reducing this risk and preventing incidents-including fires aboard aircraft or other transport vehicles. With the increased energy density comes greater risk and the need to manage it. Today's lithium cells and batteries are more energy dense than ever, bringing a steadily growing number of higher-powered devices to market. Our society has come to depend on lithium cells and batteries for an increasingly mobile lifestyle. Lithium cells and batteries power countless items that support everyday life from portable computers, cordless tools, mobile telephones, watches, to wheelchairs and motor vehicles.
