Understanding the calendering processability of Li(Ni0.33Mn0.33Co0.33)O2-based cathodes

The calendering process aims at enhancing the electrode energy density, and improving electronic conductivity, determines final porous micro/mesostructure. In this sense, one of main parameters interest is its impact in porosity (?) electrochemical performance. Here, we present a systematic study conditions (applied calender pressure roll temperature) effect on NMC-based electrodes ? terms active material/carbon additive/binder composition amount solvent used during preparation slurries. processability was assessed through cathodes compressibility resistance minimal attainable ?, mechanical properties (hardness elastic deformability), pore size distribution, film mesostructure C-rate cathode Based our results, it found that distribution organization inactive carbon black (CB)/PVdF phase are key control calendering. Electrodes with high CB/PVdF content prepared higher amounts slurry ensure good conductivity film-like structure conducting around NMC particles which upon outputs better
