Cathode material slurry containing lubricant is provided to reduce a failure rate and maximize task efficiency by minimizing residual stress of the cathode in a roll pressing process and preventing the cathode from being deformed. Cathode material slurry(121) comprises a cathode active material and a predetermined amount of lubricant. The contents of the lubricant is 0.05-10wt% on a total weight basis of the slurry in order not to deform the cathode after coating and compressing the slurry on a current collector(111). The lubricant represents wax selected from the group consisting of paraffin wax, polyethylene wax, polypropylene wax, ethylene-vinyl acetate copolymer wax, amide wax and carnauba wax. |
