Gas and dust explosions present serious hazards to underground coal mine workers. During mining operations, methane (CH₄) gas is released and can accumulate in areas with inadequate ventilation. Coal dust deposits can become airborne, creating explosive dust clouds. The ignition of CH₄ or the detonation of explosives can disperse coal dust into the air, triggering powerful secondary explosions. Similarly, gases released from oil fields are highly explosive. Electrical and electronic equipment used in coal mines or oil fields must adhere to explosion-proof requirements. Lithium-ion batteries are gaining popularity due to their high energy density and fast-charging capabilities. However, these batteries are generally unsuitable for direct use in hazardous areas. To be used safely in such environments, Li-ion batteries must comply with the design requirements of relevant safety standards. Batteries used in hazardous locations must meet the general requirements of IS/IEC 60079–0, along with specific safety standards such as IS/IEC 60079–1 for flameproof enclosures or IS/IEC 60079–11 for intrinsic safety, depending on the type of protection required. This paper examines the IEC standard requirements and improves the reliability of Li-ion batteries for safe usage in hazardous areas of underground coal mines. Several analytical and simulation have been conducted to assess the safety levels of Li-ion batteries with different loads evaluating their suitability for applications in hazardous environments.
