Example 7
The procedure was as in example 1, except that the lead-carbon battery was modified as required in example 1, and the product obtained by the hydrothermal reaction was dried and then redispersed in 250ml of a 20% by mass aqueous polyvinylpyrrolidone (PVP) solution.

The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.23 ml/(wh.h).
Comparative example 1
The process is the same as in example 1, except that according to the requirements of example 1, other conditions are not changed, the preparation of the material in step 1 is not carried out, and 0.15g of commercial activated carbon is directly added as an additive material of the lead-carbon battery to replace a composite carbon material in the preparation process of the negative electrode in step 2. The prepared electrode material has a hydrogen evolution current of 110.9738mA under the condition that the electrode potential is-1.6V.

The prepared electrode material has a hydrogen evolution current of 120.7834mA under the condition that the electrode potential is-1.6V. The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.36 ml/(wh.h). Because the addition amount of the conductive polymer material is too small, the amount of in-situ synthesized conductive polymer on the surface of the carbon material is reduced, and the coverage amount of hydrogen evolution active sites on the surface of the carbon material is insufficient, so that the effect of inhibiting hydrogen evolution is poor.
Comparative example 3:

The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.35 ml/(wh.h). Because the addition amount of the conductive polymer material pyrrole is too large, the pyrrole cannot be completely polymerized, a large amount of monomer remains in the electrode material and cannot occupy hydrogen evolution active sites on the surface of the carbon material, so that the hydrogen evolution is serious, and in addition, the internal resistance of the carbon material is further increased.
Comparative example 4:
the procedure was as in example 1 except that the lead-carbon battery was changed to 0.30g in the amount of ammonium persulfate added as required in example 1 without changing other conditions. The prepared electrode material has a hydrogen evolution current of 130.4377mA under the condition that the electrode potential is-1.6V. The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.34 ml/(wh.h). The amount of the conductive polymer synthesized in situ on the surface of the carbon material is reduced due to the too small addition amount of the oxidant, and the coverage amount of hydrogen evolution active sites on the surface of the carbon material is insufficient, so that the effect of inhibiting hydrogen evolution is poor.
Comparative example 5:
the procedure was as in example 1 except that the lead-carbon battery was changed to 3.0g in the amount of ammonium persulfate added as required in example 1 without changing other conditions. The prepared electrode material has a hydrogen evolution current of 130.2195mA under the condition that the electrode potential is-1.6V. The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.31 ml/(wh.h). The addition amount of the oxidant is too large, so that the polymerization reaction of the monomer is too strong, the polymerization of the conductive polymer layer is uneven, the aggregation is serious, the internal resistance of the material is increased, and the effect of inhibiting hydrogen evolution cannot be achieved.
Comparative example 6 (polypyrrole)
The process is the same as that of the real processExample 1 differs therefrom in that step 1 "step 1: the composite carbon material is prepared by the following method: 1. 1.952g of pyrrole was dissolved in 200ml of a blend of ultrapure water and ethanol, wherein the volume ratio of alcohol to water was 1:1 to form a solution a. 2. 0.64g of ammonium persulfate was dissolved in 40ml of water to form solution B. 3. 10g of solution A having a specific surface area of 1300m were added to 2 The activated carbon material per gram forms a mixed liquor C. 4. Mixing the solution B and the solution C and fully stirring to uniformly disperse the carbon material; "change to" step 1: the composite carbon material is prepared by the following method: 1. 1.952g of polypyrrole was dissolved in 200ml of a blend of ultrapure water and ethanol, wherein the volume ratio of alcohol to water was 1:1 to form a solution a. 2. 10g of a solution A having a specific surface area of 1300m was added 2 The active carbon material/g was mixed with 40ml of water to form a mixture B. 3. Fully stirring the solution B to uniformly disperse the carbon material; ". The prepared electrode material has a hydrogen evolution current of 152.8350mA under the condition that the electrode potential is-1.6V. The gas production rate of the lead-carbon battery of the carbon material of the formula is 0.33 ml/(wh.h). Because the conductive polymer directly introduced on the surface of the activated carbon can not be covered on the hydrogen evolution active site on the surface of the carbon material sufficiently and accurately, the effect of inhibiting hydrogen evolution can not be achieved.
By comparing hydrogen evolution current and gas production rate of the battery in different examples and comparative examples, the method of synthesizing the conductive polymer on the surface of the carbon material in situ ensures the conductivity of the composite material, simultaneously covers hydrogen evolution active sites on the surface of the carbon material, introduces polyvinylpyrrolidone on the surface of the composite carbon material, and performs sintering treatment, and the carbon shell layer formed by PVP covers the hydrogen evolution active sites on the surface of the internal composite carbon material more fully on the premise of not affecting the conductivity of the internal composite carbon material, thereby effectively reducing the peak current of hydrogen evolution in the battery charging process, and obviously reducing the hydrogen production in the battery charging process after the hydrogen evolution current is reduced.
