Free QuoteThe 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 .
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.
Conclusions LIB shell serves as the protective layer to sustain the external mechanical loading and provide an intact electrochemical reaction environment for battery charging/discharging. Our rationale was to identify the significant role of the dynamic mechanical property of battery shell material for the battery safety.
According to the relevant requirements in IEC60079, the explosion-proof protection of LIB can be adapted to the working environment of high dust and explosive gas environments such as in the mining face of coal production.
There are three explosion-proof protection technologies for LIB vehicles: Explosion-proof (Ex'd'), intrinsically safe ('ia'/'ib') and encapsulation (Ex 'ma'/'mb'). At the same time, the increased safety type (Ex 'e') or the combination of several protection technologies may also be considered to achieve the required protection level.
