The dangers of lithium battery
Lithium is a metal that is particularly susceptible to reaction. It is silver-white in appearance, very soft, stretchable, and flammable. Metallic lithium is a substance that releases flammable gases in contact with water.
A. metallic lithium properties:
(1) The water or damp air will release of flammable gas;
(2) The solid state, when the temperature exceeds its melting point 180 ℃, can burn;
(3) A powder, can burn in room temperature;
(4) Can cause serious burns and corrosion.
B. Lithium batteries or lithium battery cores are classified as Class 9 dangerous goods and their hazard depends on the content of lithium.
(1) Highly flammable lithium-ion batteries;
(2) The short circuit and overcharge, extreme temperature, error operation or other errors can be on fire;
(3) Whether it is due to internal causes or external heating or physical impact, it generates enough heat to cause thermal runaway of adjacent cells. The electrolyte released by the lithium metal battery mixes the molten lithium metal with a large pressure pulse. A flammable electrolyte and molten lithium metal can produce an explosive mixture;
(4) In the Class C cargo tank, the fire extinguishing agent Halon 1301 (trifluoromethane bromide fire extinguishing agent) cannot effectively control the ignition of the lithium metal battery.
