Research progress in dispersion technology of lithium iron phosphate cathode slurry

According to the structure and the surface chemical performance of lithium iron phosphate(LiFePO_4),the mechanism of agglomeration of slurry was expounded.The mechanism of dispersants to improve LiFePO_4 paste dispersion stability and the factors in practical dispersants application were introduced.The electrosterical mechanism of dispersants to improve LiFePO_4 paste dispersion stability was summarized,the progress in the application of dispersants in this area was reviewed.The dispersion effect of dispersants' electrochemical stability,molecular weight,adding content and the slurry feeding sequence was mainly discussed.
