“…The extrapolation to industry would therefore require the usage of a more environmentally friendly solvent and a dispersing device adapted to large-scale production. The successful transition towards an environmentally friendly aqueous processing of the graphite-based negative electrodes for lithium-ion batteries has been achieved recently [6,7]. However, for positive electrodes, instability in water of the AM can be a limitation of the utilization of an aqueous-based process [8][9][10].…”

“…al. 6 found that a strong correlation exists between particle/binder adhesion strength and the retention rate of discharge capacity. Binder properties can be particularly important for high capacity AMs, since higher capacity is associated with greater volume expansion during lithiation.…”

“…27 developed a coupled stress-strain and resistivity tester to probe simultaneously the mechanical and electrical properties of an electrode along with the Journal of The Electrochemical Society, 160 (9) A1502-A1509 (2013) A1503 binder immersed in the liquid solvent. Peel test 6,26 and scratch test 28 have been used to measure the adhesion of an electrode film to its substrate and to study the influence of suspension (used in negative electrode fabrication) on the performance of the electrode. However, these macroscopic testing methods were not able to distinguish the particle/binder/particle cohesion and electrode-film/binder/currentcollector adhesion.…”

“…Furthermore, partial substitution of CMC with PAA resulted in a significantly decreased dynamic mobility. We investigated the effect of PAA on the development of surface potential for graphite 14) and C/ LiFePO4 8) and reported that the addition of PAA does not contribute to further development of electrokinetic potential (surface charge) of particulates. Therefore, it is possible to infer that the reduced amount of CMC is responsible for the reduced dynamic mobility of nanosized LiFePO4.…”

“…It has been reported that PAA has a stronger adsorption affinity with hydrophobic surfaces than does CMC, and under basic conditions, PAA has a more favorable conformation for dispersion of particles due to electrostatic repulsive forces. 14) Rheological behaviors of C/LiFePO4 paste containing CMC and WSB with and without PAA were characterized, and the results are shown in Fig. 3.…”
