| titleOfInvention | Composite lithium battery diaphragm and preparation method thereof |
| abstract | The invention relates to the technical field of lithium battery diaphragms, and in particular relates to a composite lithium battery diaphragm and a preparation method of the composite lithium battery diaphragm. The composite lithium battery diaphragm comprises a polypropylene base body diaphragm, wherein composite coatings are sprayed on the two surfaces of the polypropylene base body diaphragm, and the composite coating is sol-like mixed solution formed by polymer and sulfonated polyimide, dissolved in solvent proportionally. The preparation method comprises the following steps: firstly, dissolving polymer and sulfonated polyimide in the solvent proportionally to form the sol-like mixed solution; secondly, coating the two surfaces of the polypropylene base body diaphragm by the mixed solution in the step I; and thirdly, drying the polypropylene base body diaphragm coated by the mixed solution in a vacuum drying oven to obtain the polypropylene composite diaphragm finally. The prepared composite diaphragm can improve the room-temperature conductivity, can greatly improve the interfacial property of the anode material and the diaphragm and Li and the diaphragm, and has good cycle performance after being assembled into the battery. |
