Figure 1 shows the distribution of CMC-Li in the LFP-based electrode. The performance of CMC-Li can be ascribed to strong hydrogen bonds resulting from the action of the –OH groups, which contributed to forming an efficient network. In addition, the hydrophilic CMC-Li binder is insoluble in organic. In the XRD chart of the electrode slices with CMC-Li as binder (Fig. 2) and LFP as cathode material, in addition to completely including the standard XRD peak of LFP,. Figure 3 shows the EIS of electrode materials in the open state. Diameter sizes of the high-frequency semicircle reflect the size of the charge transfer resistance of a. The oxidation reduction peak positions of different electrodes vary (Fig. 4). The CV curves of batteries with CMC-Li as cathode material and binder show weaker. It can be seen from Fig. 5 that the rate performance and cycle property of the electrode material with CMC-Li-3 as the binder are excellent. At a discharge rate of 0.2.
