    摘要： The opening to be sealed in a battery is sealed with an electrical insulating sealant S by placing an electrical insulating sealing material C, including a first sealing material A that is soften by heat applied for sealing and a second sealing material B that is more difficult to soften by the heat applied for sealing than the first sealing material A, and by heating and successively cooling the electrical insulating sealing material C. The second sealing material B is in the form of a mesh. Thus, a sealed battery with few defectives such as a sealing failure and a short-circuit can be manufactured in a high yield rate.

    摘要： The battery of this invention includes a positive electrode including a gelled polymeric electrolyte (A) and using spinel type lithium manganese oxide as an active material; a negative electrode; a gelled polymeric electrolyte (B) in the shape of a film or sheet also serving as a separator, and both the gelled polymeric electrolyte (A) and the gelled polymeric electrolyte (B) are made from a polymer of poly(alkylene oxide) series impregnated with a liquid electrolyte. Since the battery includes the positive electrode using the specific gelled polymeric electrolyte (A), a contact area between the positive electrode active material and the gelled polymeric electrolyte is large, so as to attain large initial discharge capacity (at high rate discharge in particular). Also, since the battery includes the specific gelled polymeric electrolyte (B) as the electrolyte, manganese included in the spinel type lithium manganese oxide is minimally eluted, and hence, the discharge capacity is minimally degraded during charge-discharge cycles due to elution of manganese, resulting in attaining good charge-discharge cycle performance.

    摘要： In a non-aqueous electrolyte battery using titanium oxide or lithium titanate as a negative electrode material for negative electrode, polymeric electrolyte is interposed between the negative electrode and a positive electrode. If titanium oxide or lithium titanate is used as the negative electrode material for negative electrode and the polymeric electrolyte is interposed between the negative electrode and the positive electrode, the polymeric electrolyte is less liable to be decomposed by catalytic reduction induced by titanium oxide or lithium titanate. This prevents decline in the charge/discharge efficiency which occurs when a non-aqueous electrolyte solution is used. Thus, the non-aqueous electrolyte battery excellent in charge/discharge efficiency is provided.
