Abstract
A battery apparatus may include: one or more battery cells; a fire-extinguishing agent, which includes a component, chemical or composition that has a combustion inhibiting or suppressing effect; a flame-resistant member having a limiting oxygen index that is higher than the oxygen concentration in the atmosphere; and a casing, which is made of a polymer and houses the battery cell(s), the fire-extinguishing agent, and the flame-resistant member. The fire-extinguishing agent may be interposed between the battery cell(s) and the casing. The flame-resistant member may be interposed between the fire-extinguishing agent and the casing.
