A lithium battery pack, comprising: at least one lithium unit cell (100, 400) comprising: at least one rectangular cathode plate (110, 410) having a cathode collector, at least one surface of the cathode collector being coated with an active material of cathode; at least one rectangular anode plate (120, 420) having an anode collector, at least one surface of the anode collector being coated with an active material of anode; at least one separation film (130, 430) inserted between cathode plate and anode plate, and providing electric insulation; a cathode terminal (140, 440) attached to a cathode plate connecting part (111, 411) which protrudes from either of two long sides of four sides of each of the at least one rectangular cathode plate; and an anode terminal (150, 450) attached to an anode plate connecting part (121, 421) which protrudes from either of two long sides of four sides of each of the at least one rectangular anode plate, wherein the separation film, the anode plate, the separation film, the cathode plate, and the separation film are laminated, and/or a plurality of the anode plates and the cathode plates are sequentially laminated between separation films, characterized in that the lithium battery pack comprises: at least two gaskets laminated on both surfaces of the lithium unit cell and located between the separation films or on one separation film; and a pair of support plates laminated on the outermost gaskets at least and protruding outwards from the gaskets so as to provide the same cooling effect as the electrode terminals (140, 440, 150, 450). at least one lithium unit cell (100, 400) comprising: at least one rectangular cathode plate (110, 410) having a cathode collector, at least one surface of the cathode collector being coated with an active material of cathode;
