Abstract

The invention discloses a preparation method of a lead accumulator anode lead paste containing a superconducting material additive. The lead accumulator anode lead paste comprises the components in parts by weight: 80-83 parts of a lead powder, 10-15 parts of water, 4-10 parts of sulfuric acid, 0.1-0.5 part of a superconducting material and 0.1-0.2 part of short fibers. The preparation method of the lead accumulator anode lead paste containing the superconducting material additive is simple and convenient, is reasonable in step design, and can relatively rapidly obtain the lead accumulator anode lead paste containing the superconducting material additive. With the superconducting material as the lead accumulator anode lead paste additive, the superconducting material can be well fused with lead paste active substances, the electrical conductivity and a microstructure of an anode plate can be effectively improved, large-volume deposition of sulfate in a discharge process is hindered, the charge acceptance capacity of batteries is increased, and the lead accumulator anode lead paste can be widely applicable to all kinds of lead-acid accumulator products.

Description

Technical field [0001] The present invention is a chemical power supply -related material field, which involves a preparation method that can be used for the positive polar lead cream that can be used for lead batteries. Background technique [0002] Leading batteries are widely used in various fields such as power, energy storage, power, and communication, with complicated types.The basic compositions participating in the electrochemical reactions in the lead battery are positive lead, positive lead cream and electrolyte.The positive lead cream is an important part of determining the overall capacity and performance of the battery.When preparing the positive lead paste, the conductive substances such as expansion graphite are generally added to improve the conductivity of the lead paste and improve the utilization rate of active substances.However, the battery has poor corrosion resistance, low stability, and large self -discharge, which causes a shorter service life of the batt...
