Raw materials such as cotton orcellulose powder, 10%-40% of a sodium hydroxide solution and lithium hydroxide a solvent and chloroacetic acid and the lick are subjected to strict condition control in a reaction kettle, so that a mixture product of sodium carboxymethyl cellulose and lithium carboxymethyl cellulose is prepared, and the ratio of sodium carboxymethyl cellulose to lithium carboxymethyl cellulose randomly ranges from10% to 90%. A slurry method is adopted for preparation, so the product flexibility is better, substituent distribution more uniform; in the pulping and coating process of the lithium battery, the flexibility of the binder is improved, the processability of the electrode plate is better, and a certain amount of lithium ions are doped in the binder, so that the total amount of the lithium ions in the whole lithium battery system can be additionally increased, the electrochemical performance of the lithium battery is improved, and the performances are incomparable better to those of sodium carboxymethyl cellulose produced by a kneading machine method.
