The invention relates to the technical field of electrode material parameter calibration, and discloses an electrode material contact parameter calibration method and device and a computer storage medium. The method comprises the following steps: performing a discrete element simulation test on an electrode material based on a calibration range and a calibration model of a contact parameter of the electrode material, then obtaining a simulation axial force-axial strain relation based on a target discrete element simulation parameter of the electrode material, judging whether the contact parameter is successfully calibrated based on the relation, and if yes, judging whether the contact parameter is successfully calibrated. And if so, determining a calibration result of the contact parameter. It can be seen that the contact parameters of the electrode material can be calibrated by adopting an experiment-simulation combined calibration method, so that compared with a direct measurement method, the experiment pro
