Abstract
Disclosed is an apparatus capable of effectively and accurately predicting a deformation characteristic in relation to swelling of a secondary battery. The secondary battery evaluation apparatus includes a fixed jig configured to hold a first secondary battery and restrict swelling of the held first secondary battery, the fixed jig measuring a change in a first reaction force of the first secondary battery according to charging and discharging cycles; a variable jig configured to hold a second secondary battery and allow swelling of the held second secondary battery, the variable jig measuring a second reaction force and a first thickness change amount of the second secondary battery according to charging and discharging cycles; and a deriving unit configured to derive a relationship between the first reaction force measured by the fixed jig and the second reaction force and the first thickness change amount measured by the variable jig.
