摘要： A thin battery comprising a battery body and a flexible package. The battery body comprises a laminate or coil including a positive plate, a negative plate, and a separator between them; and a plurality of leads connected to the positive and negative plates. The package, in which the battery body is placed, is charged with electrolyte and sealed in such a manner that the inner pressure is lower than atmospheric pressure and higher than the vapor pressure of the electrolyte. This battery is kept from generation of gas in the package during storage at high temperature and from the increase in the inner pressure due to expansion of gas.

摘要： A battery such as a lithium secondary battery having a structure permitting reduction in both weight and thickness, wherein a groove for drying the solvent used for manufacturing the battery is provided in an electrode, thereby improving the productivity of the battery. Specifically, a battery composed of a positive electrode, a negative electrode and an electrolyte holding layer, characterized in that a solvent evaporation groove (11c) is formed in at least one of the positive electrode and the negative electrode, for example, in the positive electrode (11).
