preparation example Construction
[0048] The present invention also provides a preparation method for the anode material of the above-mentioned lead-carbon super battery, comprising the following specific steps:
[0049] 1) Material preparation: Dissolve graphite oxide in water to prepare a graphite oxide solution of 0.5-10 mg / ml (preferably 0.5-3 mg / ml); dissolve soluble lead salt in deionized water to prepare a concentration of 0.01-2 mol / l lead salt solution; soluble lead salt is one or more of nitrate, acetate, carbonate, hydrochloride, sulfate and complex salts containing lead elements;
[0050] 2) Mixed material: ultrasonically treat the graphite oxide solution to disperse it into a uniform graphene oxide colloidal solution, then add the above-mentioned lead salt solution to it, oscillate ultrasonically for 5-30 minutes, and pour it into a high-pressure reactor;
[0051] 3) Hydrothermal reaction: Fix the high-pressure reactor and place it in a constant temperature explosion-proof box. The temperature of ...
Embodiment 1
[0058] Prepare an aqueous solution of lead acetate with a concentration of 0.1M, and add a graphite oxide solution with a concentration of 2ml / mg. The volume ratio of lead acetate aqueous solution to graphene oxide solution is 90:10, heated in water for 25-30 hours, dried under nitrogen at 80°C, and heat-treated in an inert atmosphere in an atmosphere furnace to obtain a lead / carbon composite material.
