Title: Inspection method for hydrogen storage alloy powder
Inventor: YAMATO KOJI
IPC: H01M4/38
Filed: 2018-04-02
Abstract: To provide an inspection method for a hydrogen storage alloy capable of determining a non-defective product on assumption of a change in physical properties of the hydrogen storage alloy over time when an electrode formed from the hydrogen storage alloy is incorporated in a battery.SOLUTION: An inspection method for a hydrogen storage alloy powder according to the present invention includes a measurement step, a calculation step, a derivation step, and a determination step. In the measurement step, in a hydrogen storage/release cycle test of the hydrogen storage alloy powder, a physical property value of any one of a particle size and a specific surface area of the hydrogen storage alloy powder is measured. In the calculation step, an index value of any one of a degree of difficulty in pulverization or a degree of a change in the specific surface area is calculated using the physical property value as the measurement target. In the derivation step, the index value that is the calculation target is compared with the correlation between the degree of difficulty in pulverization and the change in the specific surface area, and the index value that is not the calculation target is derived. In the determination step, it is determined whether or not the index value that is the calculation target and the derived index value are within the respective specified ranges.SELECTED DRAWING: Figure 1
