[0048] Experimental Example 1: Electrochemical charge and discharge performance
[0049] The charge capacity and discharge capacity were measured during the charge and discharge process according to the examples and comparative examples. The results are shown in figure 2 middle. The charge-discharge efficiency at this time is shown in image 3 middle.
[0050] refer to figure 2 , the cycle performance of the example and the cycle performance of the comparative example were similar to each other in the early cycle; however, the cycle performance of the example and the cycle performance of the comparative example were very different from each other after 50 cycles. It can be seen that the examples exhibit better performance than the comparative examples, and the difference in performance between the examples and the comparative examples becomes larger as the number of cycles increases.
[0051] refer to image 3 , it can be seen that even in the early cycle, the example ...
