Separator for electrochemical cell and method for its manufacture |
摘要 |
An electrode/separator assembly for use in an electrochemical cell includes a current collector; a porous composite electrode layer adhered to the current collector, said electrode layer comprising at least electroactive particles and a binder; and a porous composite separator layer comprising inorganic particles substantially uniformly distributed in a polymer matrix to form nanopores and having a pore volume fraction of at least 25%, wherein the separator layer is secured to the electrode layer by a solvent weld at the interface between the two layers, said weld comprising a mixture of the binder and the polymer. Methods of making and using the assembly are also described. |
