PURPOSE: A Li polymer secondary cell is provided to enhance the reliability in production and manipulation by improving the arrangement structure of anode and cathode terminals electrically connected to an external circuit. CONSTITUTION: A Li polymer secondary cell comprises a battery cell(20) and a case(11) having a receiver portion(12) for receiving the battery cell(20). In the battery cell(20), anode plates(21) and cathode plates(22) are stacked interposing separators(23). One side of each anode plates(21) is extended to form an anode tap(25), and one side of each cathode plates(22) are extended to form a cathode tap(27). The anode tap(25) is arranged at different side from the cathode tap(27). The taps(25,27) are welded to an anode terminal(29) and a cathode terminal(31) to be connected with an external circuit. The case(11) includes a lower case(11a) having the receiver portion(12) and a cover(11b) for closing the lower case(11a). |
