Abstract
According to the metal foil fatigue test system and metal foil fatigue test method of the present invention, the fatigue degree and lifespan of the metal foil may be easily predicted by injecting gas into the tube of a roll structure and discharging the gas to simulate charge/discharge of the electrode assembly.
Claims19
A system for testing fatigue of a metal foil comprising:
- a flat tube in a roll structure the metal foil laminated along with the flat tube;
- a charge/discharge simulation unit including a gas injector for injecting gas to the flat tube such that the flat tube is inflated when the gas is injected into the tube thereby stress is provided with the metal foil and a gas discharger for discharging gas from the flat tube;
- and
- a tensile strength measuring unit to measure
- tensile strength (TS1) of the metal foil before the charge/discharge simulation unit injects or discharges the gas, and
- tensile strength (TS2) of the metal foil after the charge/discharge simulation unit injects or discharges the gas.
