6 FAQs about [What materials are used in explosion-proof batteries for coal mines]
Can lithium battery pack be used in underground coal mining?
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.
What are the different types of explosion-proof protection technologies for Lib vehicles?
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.
What temperature does coal dust accumulate in a battery?
During coal mining or processing, coal dust accumulates into the explosion-proof shell of the battery. MSHA [ 106] requires that the outer surface temperature of the explosion-proof shell shall not exceed 150 °C. The ignition temperature of the coal dust cloud is 440 °C to 640 °C.
What are the applications of lithium batteries in mining machinery?
The applications of LIBs in mining machinery came soon after the automotive industries successfully revolutionised the conventional fuel-powered vehicle to produce vehicles that were fully electric-powered through various types of lithium battery technology.
What is the explosion-proof protection of Lib?
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.
How to ensure the intrinsic safety of a battery pack?
Therefore, in order to ensure the intrinsic safety of the battery pack, one strategy is to select safer cathodes and anodes, electrolytes and separator materials, and the other is to take away the heat of the thermal runaway battery in time, so as not to cause the spread of thermal runaway.
