Abstract

A battery case for a lead-acid battery molded from a resin material comprising an acrylonitrile-butadiene-styrene (ABS) resin having a Charpy impact value of 20 KJ/m2 or more and an additive comprising brominated bisphenol A as a flame retardant, antimony trioxide and a fatty acid amide, wherein the battery case meets a flammability class of UL94V-0 and the Charpy impact value of the battery case is 10 KJ/m2 or more. The fatty acid amide may be a bis-stearic acid amide. The additive may comprise 15 to 25 parts by mass of brominated bisphenol A, 5 parts by mass or more of antimony trioxide and 0.1 parts by mass or more of a fatty acid amide per 100 parts by mass of the ABS resin used. The ABS resin may have a Charpy impact value of 25 KJ/m2 or more.

The present invention may also be implemented as a lead-acid battery including the battery case according to the present invention, or a resin material f or the battery case according to the present invention, The configuration of a lead-acid battery according to an embodiment of the present invention will be described in detail below.
The leadacid battery according to the embodiment of the present invention includes a battery case including a case body and a lid member, and a positive electrode, a negative electrode, a,.separator, and an electrolyte that are housed inside the battery case..

An electrode group including positive electrodes and negative electrodes stacked via separators and an electrolyte in which the electrode group is immersed are housed inside the battery case The batery case is torrer from an AbS resin material.
in order to achieve good formability and reduce a void space during transfer, the case body preferably has a cubic or rectan9ular paraflelepiped ape. wever, the shape of the caae bo is rtot spe:LtLcaffy lim*ed as lang as the ease body has an op:ening en.d portion and the case body may bave difterent shapes such as a polygonal coluit Shái.
