PURPOSE:To eliminate the initial voltage drop by providing a negative pole employing a light metal as an active substance and a positive pole employing carbon fluoride as main active substance while added with specific chrome oxide. CONSTITUTION:In a cell having a negative pole employing light metal such as Li as an active substance and a positive pole employing nonaqueous electrolyte and carbon fluoride as main active substance, a chrome oxide shown by CrxOy (1.5<y/x<3) is added in the positive pole. consequently in the initial discharge, high potential chrome oxide is discharged precedently to increase the initial discharge voltage to provide the flat voltage characteristic essential to a carbon fluoride/Li cell and high discharge capacity. |
