| description | PROBLEM TO BE SOLVED: To provide a separator which inhibits short-circuit between a cathode and an anode even when an electrochemical element is overheated and prevents a separation phenomenon between an electrode and the separator.SOLUTION: A surface of a separator comprising a coating layer, which is formed on at least one surface of a porous substrate and made of a mixture of inorganic particles and a binder polymer, has a plurality of dots arranged at predetermined intervals and made of a polymer which is natural rubber, synthetic rubber or a copolymer comprising a styrene unit and a butadiene unit, where the average diameter of the dots is 0.1 to 10 mm and the intervals of the dots are 0.1 to 100 mm.
【課題】電気化学素子が過熱された場合にもカソードとアノードとの間の短絡を抑制し、電極とセパレータ間の分離現象が防止するセパレータの提供。【解決手段】無機物粒子及びバインダー高分子の混合物からなるコーティング層を多孔性基材の少なくとも一面に形成したセパレータの表面に、天然ゴム、合成ゴム、スチレンユニット及びブタジエンユニットを含む共重合体である高分子からなる多数のドットを互いに所定間隔離隔されて形成するセパレータ。前記ドットの平均直径が０．１〜１０ｍｍであり、間隔が０．１〜１００ｍｍであるセパレータ。【選択図】図２ |
