The loss of integrity at the electrode/SE interface would unavoidably lead to reduced performance and eventually to battery failure. Adding extra spacers indeed reduces the inner stress. The compressive stress in a battery module can surge to 0.6 MPa without soft spacers, which may cause the battery to experience severe mechanical degradation.
