preparation example Construction
[0044] A method for preparing a plastic electrode of an aqueous sodium ion battery, comprising the following steps: S1 uniformly mixing electrolyte salt and deionized water to form an electrolyte solution;
[0045] S2 Add surfactant and humectant to electrolyte solution and mix into a uniform solvent matrix;
[0046] S3 Add the conductive material to the solvent matrix, and disperse the conductive material evenly in the solvent matrix by high-speed stirring;
[0047] S4 If a positive electrode is to be prepared, the positive active material and a binder are added, and if a negative electrode is to be prepared, a negative active material and a binder are added, and then stirred at a high speed to mix evenly;
[0048] S5 is mixed with cross-linking agent at low speed to make it cross-link with the binder to form a three-dimensional network structure of plastic electrode paste for aqueous sodium-ion batteries;
[0049] In the above preparation steps, the weight percentage of eac...
