    摘要: A lithium polymer battery or multi-cell and a method of making the multi-cells. The multi-cell comprises a plurality of laminated single cell units, each unit comprising, laminated in sequence, a negative electrode current collector, a negative electrode, a first electrolyte-impregnated separator, a positive electrode, and a positive electrode current collector. These single cell units are stacked one next to another in sequence and a second electrolyte-impregnated separator is positioned between adjacent laminated cell units. The method includes positioning, in sequence, a negative electrode current collector, a negative electrode, a first porous separator, a positive electrode, and a positive electrode current collector to form a single cell unit. A plurality of the single cell units are then positioned adjacent one another in sequence, and a second porous separator is positioned between adjacent single cell units. The method further includes impregnating each of the first and second porous separators with an electrolyte and laminating each single cell unit, but adjacent cell units are not laminated to one another.
