Engineering, Harbin Engineering University, Harbin 150001, China) Abstract: Chromium doped Nano-MnO2 were synthesized by low temperature solid-state reaction. The charactrization and performance of samples were studied by X-ray diffraction. The results show that the product is the mixture of α-MnO2 and γ-MnO2, the specific capacitances of pure MnO2 and chromium doped MnO2 are 95F/g and 163F/g......
