Abstract

The invention relates to a lead-carbon storage battery cathode material and a preparation method thereof. The material is prepared by mixing and stirring a first component and a second component, wherein the first component is prepared from the following components in percentage by mass: 32%-35% of lead powder, 0.6%-1.0% of phosphoric acid, 0.3-0.5% of a carbon nano tube, 1.6%-2.2% of activated carbon, 0.3%-0.5% of magnesium sulfate, 0.3%-0.6% of paroline oil and 60.2%-64.5% of deionized water; and the second component is prepared from the following raw materials in percentage by weight: 50%-55% of silicon dioxide, 1.3%-2.5% of a carbon nano tube, 7.8%-9.6% of citric acid and 33.2%-39% of deionized water. According to the lead-carbon storage battery cathode material and the preparation method thereof, the lead-carbon storage battery cathode material has good high-rate capability, long service life and high capacity.

Description

technical field [0001] The invention relates to a negative electrode material of a lead-carbon storage battery and a preparation method thereof, belonging to the field of storage batteries. Background technique [0002] Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. Lead-acid batteries have been widely used due to their advantages of stable voltage and low price. However, the disadvantages of lead-acid batteries are also obvious, such as: low specific energy, short cycle life, easy thermal runaway, bulky batteries, low high-rate discharge efficiency, and low temperature has a great impact on battery performance (low temperature of minus 30 degrees loses charging and discharge capacity), high temperature is easy to fail, etc. [0003] Therefore, it is necessary to design a lead-carbon battery negative electrode material and a preparation method thereof to overcome the above prob...
