    • The present invention relates to separator-electrode units for lithium batteries and also to a process for their production.The separator-electrode units comprise a porous electrode which is useful as a positive electrode (cathode) or negative electrode (anode) in a lithium battery and a separator layer applied to this electrode and are characterized in that the separator-electrode units comprise a purely inorganic separator layer which comprises at least two fractions of metal oxide particles which differ from each other in their average particle size and/or in the metal. More particularly, the separator layer comprises metal oxide particles having an average particle size (Dg) which is greater than the average pore size (d) of the pores of the porous positive electrode that are bonded together by metal oxide particles having a particle size (DO which is smaller than the pores of the porous electrode.The separator-electrode unit of the invention has the advantage that it is simple to manufacture as one component and, since the step of laminating the separator onto the electrode can be omitted, that it can comprise a large variation of materials. In addition, a separator-electrode unit according to the invention possesses excellent mechanical stability and a very low separator thickness, which is why it can even be used in lithium high energy batteries.
    • 本发明涉及锂电池用隔膜电极单元及其制造方法。 分离电极单元包括可用作锂电池中的正电极(阴极)或负电极(阳极)的多孔电极和施加到该电极上的隔板层,其特征在于,隔板电极单元包括纯 无机分离器层,其包含在其平均粒度和/或金属中彼此不同的金属氧化物颗粒的至少两个级分。 更具体地说,隔板层包括平均粒径(Dg)大于多孔正极的孔的平均孔径(d)的金属氧化物颗粒,该平均孔径(d)由具有颗粒尺寸的金属氧化物颗粒 DO小于多孔电极的孔,本发明的隔膜 - 电极单元的优点在于,作为一个部件制造简单,由于可以省略将隔膜层叠在电极上的步骤,因此, 可以包括大的材料变化,另外,根据本发明的隔膜 - 电极单元具有优异的机械稳定性和非常低的隔板厚度,这就是为甚么甚至可以用于锂高能电池中的原因。
