    • The present invention relates to electrical separators for batteries, especially lithium batteries, having a shutdown mechanism and also a process for their production. An electrical separator is a separator which is used in batteries and other arrangements in which electrodes have to be separated from each other while maintaining ion conductivity for example. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a flammable solvent, for example organic carbonates. This is why it is absolutely necessary for a separator for lithium cells to possess a suitable shutdown mechanism and at the same time for it not to be able to melt down. This object is achieved by an electrical separator according to the present invention that comprises a shutdown layer which is formed from a porous sheetlike structure. Since the separator further comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator.
    • 本发明涉及一种具有关机机构的电池隔离器,特别是锂电池,以及其制造方法。 电分离器是用于电池和电极必须彼此分离的其它布置的隔膜,同时保持例如离子传导性。 安全性在锂电池中是非常重要的,因为与其他类型的电池(Pb,NiCd,NiMeH)相反,电解质的溶剂不是水而是易燃溶剂,例如有机碳酸盐。 这就是为什么锂离子电池隔板绝对需要具有合适的关断机制,同时又不能熔化的原因。 该目的通过根据本发明的电分离器实现,其包括由多孔片状结构形成的关闭层。 由于分离器还包括载体上的多孔无机(陶瓷)层,所以由于完全熔化的分离器,电池不能熔化。
