With the increase of magnetic field intensity, the PDS increases and the macrosegregation decreases. The increasing PDS and reducing segregation under the LMF can be attributed to the increase of solute boundary layer, which expands the non-equilibrium freezing temperature range and brings the effective partition coefficient closer to 1. The increase of the solute enrichment layer thickness could be caused by the downward secondary circulation generated by the thermoelectric magnetic convection (TEMC) near the interface, which drives the migration of solutes towards the interdendritic region.

However, because of the harmful effect of NMP on the environment and human health, the use of NMP and PVDF for lithium-ion batteries will be highly regulated in the future. Therefore, developing eco-friendly alternatives is crucial for formulating systems using new solvents and binders. Despite numerous efforts, these alternatives have not been widely adopted across the lithium-ion battery industry. It is due to their limited ability to compete on price or performance to replace the traditional NMP/PVDF slurry formulations. This review investigates developments in the search for new solvents and binders that can be used in cathode slurry compositions.
