[0046] Example
[0047] In this example, three lithium sources, namely lithium hydroxide, lithium carbonate and lithium peroxide, were used to prepare lithium supplementary additives. The lithium supplementary additive is respectively added to the positive electrode material and the negative electrode material, and used as the positive electrode lithium supplementary additive and the negative electrode lithium supplementary additive respectively. The effects of adding and not adding lithium supplementary additives on the first charge and discharge of the battery were tested respectively. details as follows:
[0048] Preparation method one of lithium supplement additive:
[0049] (1) Mix the carbon nanospheres with anhydrous lithium hydroxide after vacuum drying, and the masses of the carbon nanospheres and lithium hydroxide are 30g and 70g, respectively, to make a mixture; the mixing method can be a grinding method, a ball milling method or a Dry mixing method, in this exam...
