Experimental investigation to evaluate LiFePO4 batteries anode and cathode elastic properties under cyclic temperature loading conditions

Experimental investigations and associated methods are provided to characterize the mechanical properties of a lithium-ion battery accounting for operating temperature variation and thermal effects. Material properties for LiFePO4 cathode and anode samples taken from an off-the-shelf battery are evaluated in new and fatigued (subjected to charging and discharging cycles) conditions.
