Abstract (en)
[origin: WO2021219732A1] A secondary electrochemical lithium-ion cell comprises at least one composite electrode as negative electrode (10), wherein the composite electrode comprises at least one anode current collector (12) and at least one electrochemically active component which allows lithium ions to move in and out. The lithium-ion cell further comprises at least one composite electrode as positive electrode (20), wherein the composite electrode comprises at least one cathode current collector (22) and at least one electrochemically active component which allows lithium ions to move in and out. Furthermore, the negative electrode (10) and/or the positive electrode (20) have at least one region (11), in which the anode current collector (12) and/or the cathode current collector (22) is at least partially free from the electrochemically active component, and wherein this region (11) is formed as a lithium reserve.
