have prepared an MNO2-graphite composite and am currently running its cyclicability test at a rate of 5 A/g. However, I have noticed an unusual trend: as the number of cycles increases, the capacity retention is also increasing. Could you please help me understand why this might be happening?

It’s rather common for MnO₂-based composites to show increasing capacity in early cycles due to improved electrolyte penetration and structural rearrangements that enhance ion conductivity. You might find that the capacity stabilises after more cycles as the material reaches full activation.
