• Sommario/riassunto: In this work, the influence of compaction of LiNi1/3Co1/3Mn1/3O2 and graphite-based electrodes is characterized electrochemically at current rates between C/20 and 5C in a wide porosity range from uncompacted states to porosities < 20%. From the determined capacitances, gravimetric and volumetric considerations, among others, are presented in Ragone plots and correlated with the microstructural analysis findings.
