Polyelectrolyte effects on the crystallization phenomena of the lithium carbonate

► In the polyelectrolyte reactive field, lithium carbonate was influenced on shape and size. ► PAA made lithium carbonate crystals high aspect shape. ► Additive amount of PAA has optimum value at 1.0 g/L because of the agglomeration. ► In the high supersaturation, crystals changed rectangle plate shape by PAA.
