A lithium paste battery cell is provided, which includes a plurality of positive and negative plates overlapping with each other and an isolation layer, wherein the lithium paste battery cell furthercomprises a flexible support current guiding cable arranged along the surface of the positive electrode plate or the negative plate between the positive electrode plate and the negative plate, the supporting current guiding cable being located in one or more of the following positions: between the positive electrode plate and the isolation layer, between the negative electrode plate and the isolation layer, and between a plurality of isolation layers. The fluidity of an electrolyte inside the lithium paste battery can be improved by the supporting current guiding cable, and the wettability ofthe electrolyte to the positive plate and the negative plate can be improved. In addition, the supporting current guiding cable can also provide support for the positive plate and the negative plate,reduce the deformation of the positive plate and the negative plate and the pressure on the isolation layer, thereby avoiding the breakage of the isolation layer or the short circuit problem, and improving the safety of the lithium paste battery.
