| titleOfInvention | Lithium ion battery negative electrode slurry, negative electrode material, lithium ion battery and preparation method thereof |
| abstract | The invention relates to a lithium ion battery cathode slurry, a cathode material, a lithium ion battery and a preparation method thereof, and belongs to the technical field of lithium ion batteries. Comprises the following components in parts by weight: 65-75 parts of lithium-titanium composite oxide, 16-20 parts of ionic liquid modified waterborne acrylic polyurethane resin emulsion, 2-5 parts of conductive agent, 0.5-1 part of film-forming assistant, 0.5-1 part of surfactant and 150-175 parts of solvent. According to the invention, after the ionic liquid modification is carried out on the aqueous polyurethane emulsion used in the slurry, the group with positive charge on the emulsion can form better dispersibility and fusibility with the lithium-titanium composite oxide, so that the slurry can have better electrochemical performance after being prepared on the electrode. |
