摘要:
The present invention relates to a method for manufacturing slurry for coating of electrodes for use in lithium ion batteries, wherein the method comprises mixing active materials with a binder into a binder solution, and adding an organic carbonate to the binder solution to generate the slurry. The present invention also relates to a method for manufacturing electrodes for a lithium battery cell, wherein the method comprises mixing active materials with a binder into a binder solution, adding an organic carbonate to the binder solution to generate slurry, wherein the above adding step is carried out at temperature above melting temperature of the organic carbonate, coating electrode material with the slurry, drying the coating on the electrode material by drying the organic carbonate, and surface treatment of the slurry so that the electrode is prepared for use in a lithium ion battery cell. Further, the invention also relates to a method for manufacturing a lithium ion battery cell.
