Coating Technology and Equipment for Lithium Ion Electrodes

The special roller coating technology for electrode coating was chosen on the basis of rheologic property of the slurries.The electrodes segment coated on front side and backside separately in fixed length by the special designed mechanic-electronic coating equipment that controlled by the computer.The optimum designed hot air impinging dryer provided high drying efficiency for thicker slurries coating layer.The technical parameter of the coating machine could meet the requirement for manufacture of the lithium ion battery.
