Performance of LiNi1/3Mn1/3Co1/3O2/graphite batteries based on aqueous binder
This manuscript reports on the manufacturing and characterization of sodium carboxymethylcellulose-based, Li-ion positive electrodes with high active material mass loadings using only water as a solvent. The effect of different calendering forces on the aqueous processed cathode electrodes is also reported. Finally, the performance of balanced full Li-ion cells in pouch cell configuration is investigated. These Li-ion cells subjected to long-term cycling experiment displayed an average coulombic efficiency of 99.96% and retained a specific capacity of almost 70% of its initial capacity after 2000 cycles.
