Abstract:
A battery cell is disclosed having a cathode including a cathode substrate with a surface coating of a first cathode active material in a first cathode region and a second cathode active material in a second cathode region, an anode including an anode substrate having a surface coating of a first anode active material in a first anode region and a second anode active material in a second anode region, wherein a value CB1 is a ratio of a unit area capacity CsA1 of the first anode region to a unit area capacity Csc1 of the first cathode region, a value CB2 is a ratio of a unit area capacity CsA2 of the second anode region to a unit area capacity Csc2 of the second cathode region, wherein the surface coating of the cathode and/or anode is a partitioned coating including different active materials, and wherein CB2≥CB1.
