NOVELTY - The utility model model claims an optimizing device for cathode material of composite ion battery based on graphene, comprising an optimized box a sieve plate and permanent magnetic rods arranged with equal distance, the inner wall of the optimized box is equipped with a limiting plate, the inner side wall of the optimized box is equipped with two vibration motors, the vibration end of each vibration motor is fixedly connected with the bottom surface of the sieve plate, the outer surface of each permanent magnet rod is sleeved with a fixing sleeve, the back of each fixing sleeve is fixedly connected with the inner wall of the optimized box, the upper surface of the sieve plate is provided with sieve holes arranged equidistantly. the utility model provided by the heating wire is matched with the sieve plate, by increasing the temperature of the sieve plate, the micro fiber impurity in the battery cathode material is carbonized and even gasified, so as to further improve the pure degree of the graphene of the cathode material of the battery, which avoids only the simple filtering and impurity removing work, cannot further remove the impurity in the cathode material, affecting the graphene of the whole quality of the cathode material of the battery.
