PURPOSE:To increase charge-discharge performance of a secondary battery by using poly3,3,3-trifluoro-1-propyne as a positive electrode or negative electrode. CONSTITUTION:Propylene carbonate containing 1mol/l lithium perchlorate is used as electrolyte and lithium plate having a dimension of 2X2cm and a thickness of 1mm. is as a negative electrode and a lithium plate is as a reference electrode. A poly3,3,3-trifluoro-1-propyne sheet having a dimension of 2X2cm is used as a positive material 1. The positive material 1 is bonded to a titanium plate 3 which serves as a current collector with a carbon pain 2 to form an electrode. A secondary battery prepared by using this electrode has a good charge- discharge performance and less self discharge. |
