Summary: | A laminate electrochemical cell, comprising a stack of layers arranged to provides a positive electrode layer/separator layer/negative electrode layer/separator layer repeat unit, where the positive electrode layer comprises a porous composite positive electrode layer adhered to both sides of a positive current collector, said electrode layer comprising at least electroactive particles and a binder; the negative electrode layer comprises a porous composite negative electrode layer adhered to a both sides of a negative current collector, said electrode layer comprising at least electroactive particles and a binder; the separator layer comprises a porous composite separator layer comprising inorganic particles substantially uniformly distributed in a polymer matrix to form nanopores, wherein each separator layer is bonded to an adjacent electrode layer through a solvent weld at an interface between the separator layer and the electrode layer. |
