The invention provides a high-temperature-resistant lead-carbon battery negative electrode material and a manufacturing process thereof. The high-temperature-resistant lead-carbon battery negative electrode material is formed by mixing and stirring a first component and a second component, wherein the first component is prepared from the following ingredients in mass ratio: 28-36% of lead powder, 0.6-1.3% of sodium phosphate, 0.3-0.6% of graphite, 0.2-0.4% of stannous monosulphate and 61.7-69.7% of deionized water; and the second component is prepared from the following ingredients in mass ratio: 5-8% of PTFE, 12-18% of sodium carboxymethylcellulose, 6-10% of phosphoric acid and 64-72% of deionized water. By adopting the high-temperature-resistant lead-carbon battery negative electrode material and the manufacturing process thereof which are provided by the invention, the stability of the negative electrode material is improved, the negative electrode material has good high temperature resistance, 1C discharging capacity at high temperature is improved, and the discharge recycling life at high temperature is prolonged, so that the high-temperature-resistant lead-carbon battery negative electrode material is more adaptable to a severe environment, especially a high temperature environment, and the high-temperature-resistant lead-carbon battery negative electrode material is especially applicable to a solar battery.
Description
technical field [0001] The invention belongs to the field of storage batteries, and relates to a high-temperature-resistant lead-carbon storage battery negative electrode material and a manufacturing method thereof. 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] What's more serious is that the performance of lead-acid batteries is severely affected by temperature, which seriously ...
