Abstract

Recently, because diffusion of cordless machine and smart card and so on, and concern of unpolluted materials, one are concerned with Li secondary batteries. Li secondary batteries have high voltage, high energy density and high power density, and heavy metal pollution problems are little. Mn is low price and is distributed much quantity. Therefore, we investigated $MnO_2$. In this study, we worked the electrochemical properties and charge/discharge characteristics of $MnO_2/Li$ cells. In results, the more heating temperature is high, the more ${\gamma}-phase$ varied ${\beta}-phase$, and when $MnO_2$ is heated at $320^{\circ}C$ and super-s-black 20wt% is mixed, characteristics are the best.
