Embodiment 1
[0034] Assemble the newly prepared positive electrode A into a button battery, connect it to the blue battery tester for battery cycle test, cycle 5 times and finish charging, disassemble the battery in the glove box, take out the positive electrode B, and use 1, 3 -After washing with dioxolane for several times, turn it out to dry at 70°C, and then carry out the characterization test.
[0035] Qualitative analysis: the positive electrode A and the positive electrode B at the end of 5 cycles of charging were respectively loaded in a scanning electron microscope to test the changes in electrode morphology before and after battery operation ( figure 1 shown). Depend on figure 1 It can be seen that significant changes have taken place on the surface of the material before and after the cycle. Before the cycle, the surface of the material is relatively smooth, and no obvious sulfur particles exist. After the cycle, the surface of the material is obviously attached to the surfac...
