FIELD: electricity.
SUBSTANCE: according to the invention, an organic/inorganic composite divider contains a porous substrate with pores; and a porous active layer containing a mixture of inorganic particles and a binding polymer which covers at least one surface of said porous substrate. The porous active layer is characterised by a thickness-through composition morphology heterogeneity where the quantitative relation 'binding polymer/inorganic particles' on the surface layer is higher than the quantitative relation 'binding polymer/inorganic particles' inside the surface layer.
EFFECT: improved performance of an accumulator.
