High-power Li-ion cells tested at elevated temperatures showed a significant impedance rise, which was associated primarily with the LiNi 0 . 8 Co 0 . 1 5 Al 0 . 0 5 O 2 cathode. Raman microscopy mapping provided evidence that the surface composition ratio between LiNi 0 . 8 Co 0 . 1 5 Al 0 . 0 5 O 2 and carbon in the composite cathode increases upon cell aging and cycling. Current-sensing atomic force microscopy imaging of single grains of pristine LiNi 0 . 8 Co 0 . 1 5 Al 0 . 0 5 O 2 powder revealed poor residual electronic contact between submicrometer primary particles within LiNi 0 . 8 Co 0 . 1 5 Al 0 . 0 5 O 2 agglomerates. Carbon retreat or rearrangement that occurs during cell testing allows residual interparticle resistance to dominate cathode interfacial charge-transfer impedance and accounts for the observed cell power and capacity loss.
