AI Customer ServiceThe capacities of the SR-P-GF diaphragm battery at current densities of 0.1, 0.3, 0.5, 0.7, 1, 2, and 3 Ag −1 are 399.6, 371.7, 354.2, 307.1, 261.1, 175.6, and 126.4 mA h g −1, respectively, and the capacity is much higher than that of the GF diaphragm battery at a current density of 1 Ag −1.
It can be seen that the SR-P-GF diaphragm battery has a better rate performance. When the current density is restored to 0.1 Ag −1, the capacity can still be restored to the initial level, and it has a very good capacity retention rate at a current density of 0.1–0.5 Ag −1, which is even 26.06 % higher than the GF diaphragm battery.
The results indicate that the electrochemical performance of zinc ion batteries can be significantly increased by using SR-P-GF diaphragm materials. This study is expected to be a low-cost and efficient method to condition the diaphragm materials for zinc ion batteries to achieve higher performance zinc ion batteries. 2. Experiment section 2.1.
Fig. 5 (a) is a CV curve of a battery using a SR-P-GF diaphragm. It can be clearly observed that the manganese dioxide in the battery exhibits a typical and obvious redox peak at a scan rate of 0.8–1.8 V, and its shape does not change significantly with the increase in the scan rate, proving that it has high reversibility.
Due to the formation of by-products and zinc dendrites, many irregular sheet structures appeared on the surface of GF diaphragm material after cycling, which hindered the transport of zinc ions to a certain extent, resulting in the degradation of the electrochemical properties of the battery (Fig. S16 a).
SR-P-GF diaphragm material is still uniformly anchored to the diaphragm surface after cycling, and the formation of zinc dendrites and by-products is limited through the combined effect of promoting zinc ion transport and auxiliary dissolution (Fig. S16 b).
