Document Type and Number:
Japanese Patent JP6947277
Kind Code:
B2
Abstract:
A method of evaluating a power storage device includes at least [a] to [f] below. [a] A power storage device (101) is prepared. [b] A charge level of the power storage device (101) is adjusted to produce a first potential difference between a positive electrode (10) and a negative electrode (20). [c] The positive electrode (10) or the negative electrode (20) is selected as a reference electrode. [d] After the charge level is adjusted, an operation to insert a conductive rod-shaped member (1) into a stack portion (50) along a direction of stack of the positive electrode (10) and the negative electrode (20) is performed while a second potential difference between the reference electrode and the rod-shaped member (1) is measured, [e] The rod-shaped member (1) is stopped. [f] The power storage device (101) is evaluated based on a state of the power storage device (101) after the rod-shaped member (1) is stopped.
