SECONDARY BATTERY

摘要

PURPOSE:To increase charge-discharge performance of a secondary battery by using cyclized polynitrile acetylene as a positive electrode. CONSTITUTION:An electrode is formed in such a way that a positive material 1 prepared by press-molding 50mg of cyclized polynitrile acetylene powder in a 2X2cm sheet is bonded to a titanium plate 3 which serves as a current collector with carbon paint 2. Electrolyte prepared by dissolving 1mol/l lithium perchlorate in propylene carbonate and a lithium negative electrode having a dimension of 2X2cm and a thickness of 1mm. are used with the positive electrode to obtain a secondary battery having increased charge-discharge capacity.
