0001 The present application relates to a battery cell assembly, a manufacturing method therefor, a battery cell, a battery and an electrical device. The battery cell assembly comprises a first electrode sheet, a plurality of second electrode sheets and separators. The separators are arranged on two opposite sides of the first electrode sheet and are combined with the first electrode sheet so as to form a combined sheet, and the combined sheet is configured to be continuously Z-folded so as to form a plurality of sub-combined sheets, there being arranged one second electrode sheet between any two adjacent sub-combined sheets. In the length direction of the second electrode sheets, an isolation layer is connected between at least one side edge of each second electrode sheet and each sub-combined sheet. Since the isolation layers can connect the second electrode sheets to the sub-combined sheets, the distance between the second electrode sheets and the sub-combined sheets is shortened, thereby reducing gaps at corners of the combined sheet, improving the transport dynamic performance of a battery, and reducing phenomena of lithium plating at edges. In addition, when lithium-plating accumulation occurs at the edges, the provision of the isolation layers will stop dendrites generated by the lithium plating from puncturing the separators, thereby reducing risks of short circuits due to the connection between positive and negative electrodes.
