摘要： There is provided a manufacturing process (S I) of a battery (1) equipped with a case (10) and an electrode body (20) having a positive electrode (21), a negative electrode (22) and separators (23, 24). The electrode body (20) has an upper R portion (20a) and the respective separators (23, 24) have surplus portions (23a, 24a). The case (10) has an accommodation portion (11) that has an opening in an upper face thereof and accommodates the electrode body, and a lid portion (12) that closes up the opening in the upper face of the accommodation portion (11). This manufacturing process (SI) includes a process (S20) in which the battery (1) is charged while being bound such that the electrode body (20) is pressed via the accommodation portion (11), with the surplus portions (23 a, 24a) of the plurality of the separators (23, 24) not located at an upper R portion (20a) of the electrode body (20), and a process (S30) in which the battery (1) that has been subjected to the initial charging process (S20) is maintained at a predetermined high temperature.

摘要： An inspection method of a present electrical storage device (1) includes: constituting a circuit (3) with the electrical storage device (1) being charged and a power supply (4), and passing a current (IB) by the power supply (4) to the circuit (3) in a direction of charging or discharging the electrical storage device (1); and in passing the current (IB), determining the quality of the electrical storage device (1) based on a converging state of the passing current (IB). In passing the current (IB), an output voltage (VS) of the power supply (4) is changed from an initial value with the passage of time.
