battery manganese
6.Testing technologies and its importance of some important physical properties of powder materials were briefly described. The influences of electrolytic manganese dioxide(EMD) particle size distribution,surface area testing results and physical properties of zinc powder on alkaline Zn/MnO_2 battery properties were also briefly discussed.
7.The modified spinel lithium-manganese oxygen LiAl_(0.2) Mn_(1.8)O_(4-x)F_x as cathode material for ion battery was synthesized by solid state reaction. The crystal structure and electrochemical performance of the samples were studied by XRD,EDS and charge-discharge tests.
