Figure 6.7 is an ultrasonic cell crusher, IS-RPB, the life cycle curve prepared MnO2 three emulsifying apparatus a high speed disperser / PPy composite. MnO2 / PPy composite constant through 1000 cycles after charge-discharge cycle were lower than the capacity, the capacity retention ratio was 93.5%, 94.1% and 87.45%, respectively. As can be seen from the composite material specific capacity retention, the specific capacity of the fine emulsion prepared IS-RPB synthesis MnO2 / PPy composite to ultrasonic cell disruption retention rate machine, seen from the above analysis, the miniemulsion was prepared in the IS-RPB more ultrasonic cell crusher dropwise large, the composite particle formed will be slightly larger, and more conducive to transport electronic charge, hindering reduction, oxidation-reduction reaction thus sufficiently increase the specific capacity. By MnO2 / PPy electrode prepared specific capacity and other synthetic methods and specific capacity retention rate vs. can be seen (see Table 6.6), the composite electrode prepared by Method miniemulsion method can also achieve the effects other than the capacity retention ratio, said details emulsion is an effective method of MnO2 / PPy composite prepared.

Figure 6.7 is the cycle life curve of MnO2/PPy composite materials prepared by ultrasonic cell crushers, IS-RPB, and high-speed dispersers. MnO2/PPy composite materials after 1000 turns of constant current charge and discharge cycle, the ratio of capacity is reduced, the capacity retention rate is 93.5%, 94.1% and 87.45%, respectively. From the composite material ratio capacity retention rate can be seen, IS-RPB prepared fine emulsion synthesis MnO2 /PPy composite material ratio capacity retention rate is higher than ultrasonic cell crusher, from the above analysis can be seen that IS-RPB prepared fine emulsion droplets than ultrasonic cell crusher, the formation of composite material particle size is also slightly larger, more conducive to electron and charge transmission, hindering reduction, so the reproduction of sufficient reproduction, than capacity increase. By comparing the ratio and capacity retention of MnO2/PPy electrodes prepared by other synthetic methods (see Table 6.6), the composite electrode ratio of fine emulsion method can also achieve the effect of other methods, and the detailed emulsion method is an effective method for preparing MnO2/PPy composite materials.

Figure 6.7 shows the cycle life curve of MnO2 / PPy composite prepared by ultrasonic cell breaker, IS-RPB and high-speed disperser. After 1000 cycles of constant current charge and discharge, the specific capacity of MnO2 / PPy composite decreased, and the specific capacity retention rates were 93.5%, 94.1% and 87.45%, respectively. It can be seen from the retention rate of specific capacity of composite materials that the specific capacity retention rate of MnO2/PPy composite prepared by IS-RPB is higher than that of ultrasonic cell crusher. From the above analysis, it is known that the droplets produced by IS-RPB are larger than that of ultrasonic cell crusher, and the particle size of composite material is also slightly larger, which is more conducive to the transmission of electrons and charges, and hinders the reduction. The reduction reaction is sufficient and the specific capacity is increased. By comparing the specific capacity and specific capacity retention of MnO2/PPy electrodes prepared by other synthetic methods, it can be seen that (see table 6.6), the specific capacity retention rate of composite electrodes prepared by miniemulsion method can also achieve the effect of other methods, indicating that miniemulsion is an effective way to prepare MnO2/PPy composite materials.
