In coal mining industry, specifically in underground coal mining, the requirements on lithium battery pack applications are very stringent with various engineering constraints imposed on them, which, in most cases, make the application of lithium technology in such an environment unfeasible or impractical.
The mining industry has encountered difficulties in deploying large LIB packs (more than 100 kWh) for the underground coal environment, and currently, most battery applications are only in low-power devices with currents drawn in the milli-amperes range .
Despite the rapid progress in material development and technology for higher-energy-density and safer lithium batteries, current lithium battery technology is still exposed to the risk of thermal runaway, although the probability is relatively low.
While the cells enclosed in an explosion-proof box are considered to be safe, there are reports that the thermal runaway propagation from a single cell will ignite the space within the enclosure to a pressure far beyond its limit [12, 18, 19].
In some mines, a traction battery pack with energy up to 100 kWh will need an explosion-proof enclosure that could withstand internal pressure of up to 1.5 MPa (15 bar) .
An encapsulated method is proposed for largescale Li-ion battery thermal runaway protection. A series of nail penetration experiment are conducted for thermal abuse analysis. Data-intensive modeling is designed for single and 10 cell pack thermal abuse simulation.
