▎ 摘  要

NOVELTY - The method involves adding graphite in reactor sulfuric acid solution. De-ionized water is added into hydrogen peroxide solution. Dispersed graphene oxide liquid is filled into a centrifuge tube. The de-ionized water is added into the centrifuge tube to remove upper layer liquid. A hydrothermal reaction kettle is heated at 95 degrees centigrade. A plaster is formed with sticky paste-shaped substance. Temperature of the high strength graphite oxide gel is maintained at 40 degrees centigrade. An adhesive paste material is coated on a lithium ion battery. USE - Method for preparing high strength gel graphene oxide of lead batteries carbon negative electrode material. ADVANTAGE - The method enables improving active material utilization rate of a lead carbonic battery, and ensuring high strength and large current charging and discharging tolerance ability of the lead-carbonic battery with super capacitor effect. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing results a method for preparing high strength gel graphene oxide of lead batteries carbon negative electrode material.'(Drawing includes non-English language text)'
