Abstract: A battery apparatus may include: one or more battery cells; one or more fire-extinguishing agents, which include(s) a component that provides a negative-catalyst effect with respect to combustion; and a casing, which houses the battery cell(s) and the fire-extinguishing agent(s). In the event that one or more of the battery cell(s) has (have) been subject to inappropriate handling and consequently has (have) ignited, the fire can be rapidly extinguished by the negative-catalyst effect of the fire-extinguishing agent(s). In addition, if one or more of the battery cell(s) of the battery apparatus has (have) ignited, because the fire can be rapidly extinguished, spreading of the fire to other battery cells, the casing, etc. can be inhibited.

Abstract: A female and male connecting structure is provided between a battery pack and a tool main body such that the battery is slidably attached and electrically connected to the tool main body. The female and male connecting structure includes male terminals provided on the tool main body and female terminals provided on the battery pack. A level difference is formed by a concave portion on a sliding surface of terminal portions of the male terminal in a thickness direction of the plate-shaped male terminal. The level difference is made at a plurality of positions to form concavo-convex portions. The sliding surface corresponds to an area with which a contact point of the female terminal comes into sliding contact, and oxidized films formed on the surfaces of the terminal portions can be removed and/or scraped by the concavo-convex portions.
