    • The present invention provides a method for maintaining the specific gravity of acid in a lead-acid battery within a predetermined range to prevent undesirable plate degradation and gassing during storage. Extended shelf-life is accomplished by employing a battery which is formed to the desired voltage and which is stored in a damp condition with the electrolyte maintained in a range which, in the most preferred embodiment, is between about 1.015 and 1.320. A desiccant, for example a gelled sulfuric acid desiccant, is placed in the battery housing, out of contact with the plates, to absorb the water vapor which is generated by the self-discharge reactions. The amount of desiccant is selected so that all the water vapor formed during such reactions is removed to maintain the specific gravity of the electrolyte in said range. Extended shelf-life results, and the desiccant can be used to form the battery electrolyte at the time it is desired to place the battery in service.
    • 本发明提供一种将铅酸电池中的酸的比重保持在预定范围内的方法,以防止在储存期间不期望的板劣化和气化。 延长保质期是通过使用形成为期望电压并且在潮湿条件下储存的电池来实现的,其中电解液保持在最优选的实施方案中在约1.015和1.320之间的范围内。 将干燥剂,例如凝胶硫酸干燥剂放置在电池壳体中,与板不接触,以吸收由自放电反应产生的水蒸汽。 选择干燥剂的量使得在这种反应期间形成的所有水蒸汽被去除以将电解质的比重维持在所述范围内。 扩展保质期的结果,并且干燥剂可以用于在期望将电池放置在使用中时形成电池电解质。

    • A thin, bipolar, lead-acid battery includes one or more cells, each of which is provided with a one-way vent for allowing release of gas generated during battery formation or overcharge. A planar spacer, having a cut out central portion, receives the electrode and separator components, and has one or more passageways formed therein extending from the wall of the cut out portion to the exterior of one of its edges. The spacer then resembles a frame for the battery components. Film sheets are applied to the opposed surfaces of the spacer and extend outwardly therefrom, at least in the vicinity of the spacer hole. The film is sealed, e.g. by heat, in all exterior areas except adjacent the hole. An oil, such as a silicone oil, is used between the film sheet in the non sealed area to form a one way "duck bill" type vent valve.
    • 薄的双极性铅酸电池包括一个或多个电池,每个电池都设有单向通风口,用于释放在电池形成或过充电期间产生的气体。 具有切出的中心部分的平面间隔件容纳电极和分离器部件,并且具有形成在其中的一个或多个通道,其从切出部分的壁延伸到其一个边缘的外部。 然后间隔物类似于电池组件的框架。 膜片被施加到间隔件的相对表面上,至少在间隔孔附近从外表面延伸。 该膜被密封,例如 通过加热,除了邻近孔外的所有外部区域。 在非密封区域中的膜片之间使用诸如硅油的油以形成单向“鸭帐单”型排气阀。
