A structure of an electrochemical separation membrane and a manufacturing method for fabricating the same are disclosed. The structure of an electrochemical separation membrane includes a base-phased polymer part in form of a continuous phase structure, a fabric-supported part distributed in the base-phased polymer part in striped shape to provide mechanic strength thereto, and inorganic particles distributed uniformly in the base-phased polymer part with 0.1 wt %˜50 wt %, wherein the fabric-supported part is a porous structure with a plurality of micro holes such that the base-phased polymer part filled into the micro holes to obtain better adhesive strength, inorganic particles distributed uniformly in the base-phased polymer part to reduce the shrinking of separation membrane and hence improving the thermal stability under high temperature. A lithium ion battery applying the electrochemical separation membrane of the present invention can reduce resistance, increase charge/discharge capacitance and prolong lifespan. |
