1. A process for producing a LiBOB.(n 5-membered ring ester) complex comprising the steps of:
producing a crude LiBOB solution by dissolving crude LiBOB in a solvate-forming solvent, wherein the solvate forming solvent contains at least one cyclic 5-membered ring ester as a substantial constituent or consists entirely thereof; separating insoluble particles of LiBOB; concentrating the resulting clear LiBOB solution to smaller volume by evaporative crystallization until solid LiBOB.(n 5-membered ring ester) complex is precipitated; and isolating the precipitated LiBOB.(n 5-membered ring ester) complex by a second solid/liquid separation process; wherein the LiBOB.(n 5-membered ring ester) complex has a residual solvent content of less than 50 wt. % wherein n is between 0.01 and 5, and wherein the LiBOB.(n 5-membered ring ester) crystalline, low-dust and completely soluble in aprotic solvents. |
