<p>A cell comprising an electrolyte container in which a positive plate with a positive active material layer and a negative plate with a negative active material layer are disposed with a porous separator interposed. The porous separator comprises at least one layer of insulating particles, which has a three-dimensional network structure of pores so that pores may allow the passage of ions. The cell can exhibit excellent discharge characteristics at a high current density without spoiling safety, can increase the amounts of the active materials that can be stored per unit volume of the cell and can exhibit higher performance than the conventional cells.</p> |
