Here, the combustion triangle theory was used to explain the battery fire and explosion. The three components are also necessary for combustion or burning in lithium ion battery. The main fuel in lithium ion battery is electrolyte, which is a solution consists of organic solvent and inorganic salt.
Safety problem is always a big obstacle for lithium battery marching to large scale application. However, the knowledge on the battery combustion behavior is limited. To investigate the combustion behavior of large scale lithium battery, three 50 Ah Li (NixCoyMnz)O2/Li4Ti5O12 batteries under different state of charge (SOC) were heated to fire.
The first results show that the combustion of such particles in gas mixtures and pure CO 2 undergoes two phases, a combustion of lithium vapour in a flame with a certain stand-off distance from the particle, followed by a combustion process taking place close to the particle surface.
The Li0.5CoO2 thermal behavior at elevated temperature. Heating rate: 0.2 oC·min-1. The lithium ion battery is a closed system and was separated from air, so in normal using there is no explosion or fire dangerous, but the abusing of lithium ion battery will generate the danger of thermal runaway.
The fuel, oxygen and energy provide the probability of fire and explosion, as the lithium ion battery is a closed system, so the gas products cause the increasing of the inner pressure and the exothermic heats heat up the system. With the rising up of the battery temperature, more chemical reactions occur, and more heat generation.
Small amounts of water vapour catalyse the reaction of lithium with other gases. Power plants require sufficiently short burning times for complete fuel conversion, leading to the concept of small particle or droplet combustion. The information available on the combustion of single droplets or particles in the sub-mm range is limited.
