Abstract Copper sulfide shows some unique physico\u2010chemical properties that make it appealing as a cathode active material (CAM) for solid\u2010state batteries (SSBs). The most peculiar feature of the electrode reaction is the reversible formation of \u00b5m\u2010sized Cu crystals during cycling, despite its large theoretical volume change (75%). Here, the dynamic microstructural evolution of CuS cathodes in SSBs is studied using in situ synchrotron X\u2010ray tomography. The formation of \u00b5m\u2010sized Cu within the CAM particles can be clearly followed. This process is accompanied by crack formation that can be prevented by increasing the stack pressure from 26 to 40 MPa. Both the Cu inclusions and cracks show a preferential orientation perpendicular to the cell stack pressure, which can be a result of a z\u2010oriented expansion of the CAM particles during lithiation. In addition, cycling leads to a z\u2010oriented reversible displacement of the cathode pellet, which is linked to the plating\/stripping of the Li counter electrode. The pronounced structural changes cause pressure changes of up to 6 MPa within the cell, as determined by operando stack pressure measurements. Reasons for the reversibility of the electrode reaction are discussed and are attributed to the favorable combination of soft materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
