| Abstract: | A series of polysulfide cyclopentadiene polymers(PCP) were prepared by chemical methods The measurements such as element analysis, SEM, constant current charge and discharge and cyclic voltammetry were performed with the samples of PCP Results showed that the samples had high initial discharge capacity The highest initial discharge capacity was 630 9mAh/g The PCP also had a good discharging platform and cycle life The discharge capacity raised with the increase of the numbers of sulfurs of the sulfur sulfur bonds in PCP |
