摘要： A lead-acid battery for idling stop includes a cell chamber, and an electrode group and an electrolyte solution stored in the cell chamber. The electrode group includes a positive electrode plate, a negative electrode plate, and a separator interposed between the positive electrode plate and the negative electrode plate. The separator includes a first rib facing the positive electrode plate and a second rib facing the negative electrode plate. The difference D between the inner dimension of the cell chamber and the thickness of the electrode group is more than 0.4 mm and less than 3.5 mm. The inner dimension of the cell chamber is a distance between a pair of inner walls each facing the positive electrode plate or the negative electrode plate in the cell chamber.

摘要： A lead-acid battery includes a positive electrode plate, a negative electrode plate, a separator interposed between the positive electrode plate and the negative electrode plate, and an electrolyte solution. The separator includes a rib on at least the negative electrode plate side. The negative electrode plate includes a negative electrode material, and the negative electrode material contains carbon particles. The carbon particles include first carbon particles having a particle size of less than 32 µm, and the first carbon particles include second carbon particles having a particle size smaller than an average pore size of the separator. A content of the first carbon particles in the negative electrode material is 0.2% by mass or more and 2% by mass or less.

摘要： A lead-acid battery includes a negative electrode material containing graphite or carbon fiber, and barium sulfate or elemental barium. A ratio S/W of an average plate interval S im mm between a negative electrode plate and a positive electrode plate and a mass W in g of the negative electrode material per one negative electrode plate in the battery is 0.01 mm/g or more. This allows to decrease the battery permeation short circuit occurrence rate and to obtain a lead-acid battery with improved performances especially when used in an environment involving deep discharge.

摘要： In a negative electrode material of a negative electrode plate of a lead-acid battery, a concentration of Ba sulfate contained in the electrode material after full charge is 1.0 mass% or more, and the Na concentration in the electrolyte solution is 0.04 mol/L or less. The lead-acid battery is excellent in terms of charge acceptance performance in the case where the battery is charged after some time following discharge.

摘要： A method for manufacturing a lead-acid battery that has an electrode group in which a plurality of positive electrode plates and a plurality of negative electrode plates are stacked via a separator includes processing the separator into a bag shape having a first region and a second region facing each other. The step of processing the separator into a bag shape includes forming a joint part that includes at least a part of the first region and at least a part of the second region. A plurality of first ribs are provided in the first region, a plurality of second ribs are provided in the second region, and the step of forming the joint part includes making the first region and the second region face each other so that at least one of the first ribs and at least one of the second ribs intersect at the joint part.
