摘要： PURPOSE:To remove adhesive moisture and enhance the preservative property of the anode body for a lithium battery, by heating and drying a molded anode body for a lithium battery in a specifed vacuum, at a specifed temperature. CONSTITUTION:A molded anode body 8 for a lithium battery is charged into a flask 16, then heated and dried on a mantle heater 14, while the flask is degassed from a vacuum pipe 13. Next, the temperature in the flask 16 is made to lower up to about ordinary temperature, before a electrolyte is poured from a tank 10 into the flask 16 by opening a cock 11, then the anode body 8 is impregnated and a battery is structured in a globe-box. The flask which is filled with dried argon may be placed in the globe-box instead of impregnation with electrolyte. In this case, the vacuum degree is an attained vacuum pressure of below 10 Torr, and the preferable treatment temperature is 100-180 deg.C. Also, the positive body 8 can be obtained by heat-treating the mixture of manganese dioxide, conductive agent and binding agent in the air at 300 deg.C., then crushing and molding; the positive body 8 is preferred to the positive body for a non-aqueous, solid electrolyte battery. Thereby, adhesive moisture can be removed and also the preservative property enhanced.

摘要： PURPOSE:To obtain a nonaqueous electrolyte battery showing excellent discharge capacity while improving a utilization rate of manganese dioxide by limiting the most suitable grain diameter of manganese dioxide powder used for a positive pole active material. CONSTITUTION:A utilization rate of manganese dioxide can be sharply improved while attaining about 100% by a method in which the average grain diameter of manganese dioxide powder, which is an active material of the positive pole 1, is made not to exceed 30mum, its amount is made to be 80-97 weight% and the average grain diameter of carbon powder,which is a conductive agent, is made not to exceed 5mum while making its amount to be 20-30 weight%. Further, lithium,natrium, potassium, magnesium, calcium, alminium or alloys thereof can be used for light metal as a negative pole active material. However, lithium or the alloy of lithium and alminium are the most suitable negative pole active material. Acetylene black and graphite can be used as carbon powder.

摘要： PURPOSE:To prevent the damage of an anode in use due to deformation, expansion, cracks or the like, by subjecting a smallish pre-molded anode body to heat-treatment, then by secondary molding the pre-molded anode body to a certain size, by leaving the pre-molded anode body as it is. CONSTITUTION:An anode body is smallishly pre-molded in external diameter, smaller by 3-10% or so than that of an objective size; the specified sized anode body used can be produced by subjecting the pre-molded anode body to heat-treatment and then to secondary molding to form the aimed anode body or by leaving the pre-molded anode body as it is to form the aimed anode body. Here, a compression molded anode body made of anode materials, conductive agents (particularly, carbon powder, acetylene black), and binding agents is expanded after compression, after heat-treatment, and after impregnation with electrolyte. Considering this expansion, the anode body which was previously pre-molded smallishly and expanded by a specified treatment can be employed as the anode body 9 by secondary molding or by leaving as it is. Thereby, the damage of the anode body due to deformation expansion, cracks, or the like, can be prevented.
摘要翻译：目的：为了防止由于变形，膨胀，裂纹等引起的使用中的阳极的损坏，通过将较小的预模制阳极体进行热处理，然后通过将预模制阳极体二次模制成一定尺寸通过将原模制的阳极体原样放置。构成：阳极体在外径上小型预成型，比目标尺寸小3-10％左右; 所使用的规定尺寸的阳极体可以通过对预先模制的阳极体进行热处理然后进行二次模塑来形成目标阳极体，或者通过将模制前的阳极体原样留下来形成目标阳极体来制造。这里，由负极材料，导电剂（特别是碳粉末，乙炔黑）和粘结剂制成的压缩成型阳极体在压缩后，热处理后，浸渍电解液后膨胀。考虑到这种膨胀，预先通过特定处理预先模制和膨胀的阳极体可以通过二次模制或通过离开而被用作阳极体9。因此，可以防止由于变形膨胀，裂纹等引起的阳极体的损伤。
