PROCEDIMIENTO PARA LA OBTENCION DE UNA MATERIA ACTIVA POSITIVA A BASE DE DIOXIDO DE MANGANESO PARA GENERADOR ELECTROQUIMICO |
摘要 |
The invention relates to a process for preparing a positive active material for a galvanic cell based on manganese dioxide. The starting material is a manganese dioxide other than beta -MnO2, an aqueous solution is added and the mixture is heated to a temperature equal to or higher than 100 DEG C. This temperature is maintained until a form of manganese dioxide is obtained whose infrared absorption maximum has a wave number between 530 cm<-1> and 560 cm<-1>. …<IMAGE>… |
