| Abstract: | Using CoCl2 and NaOH solution as raw meterial, Co（OH） 2 precipitation is got by mixing reaction,then the Co3O4 nanometer particle which diameter is 100 nm are prepared by frontal precipitation searing. The sample is characterized by XRD and TEM technology. The result shows, the charge - discharge capacity of electrode which prepared by frontal namometer flake Co3O4 can reach to 100 mA ·h/ g when current density is 0.2 mA · cm^-2 |
