PURPOSE:To obtain a solid state secondary battery, especially a solid state thin film lithium secondary battery capable of charging at high current density by incorporating a temperature control function. CONSTITUTION:In solid state thin film secondary battery manufactured by stacking a positive electrode, solid electrolyte, and a negative electrode on a substrate, a temperature control function is incorporated. For example, the temperature control is functioned with a thin film resistance formed on the substrate. The mobility of reaction chemical species in the negative electrode, the solid electrolyte, and the positive electrode, which is a factor limiting charge current density in the solid state thin film secondary battery, is increased by optimizing the temperature of the battery and charging current density is increased. The positive electrode, solid electrolyte, negative electrode, and the heat generating thin film are formed by a printing process, or the heating unit is bonded to the substrate or sealing part to incorporate the temperature control function in the battery. |
