PURPOSE:To obtain a battery plate having uniform discharge capacity and good current collecting efficiency by crushing an active material mix in a wet state containing liquid such as water or alcohol, drying, and molding. CONSTITUTION:A battery active material mix kneaded with conductive material and binder is crushed in a wet state containing liquid such as water or alcohol, and dried, then a specified amount of the mix is molded. Since conductive material in the mix has adsorbed water or alcohol, apparent density of the conductive material is similar to that of active material. Therefore, when the mix is crushed, separation of the active material from the conductive material is prevented. Since uniform mix powder is obtained, a battery plate whose discharge capacity is made uniform and current collecting efficiency is increased can be obtained. |
