Description

It adds activated carbon to the negative electrode of the lead-acid battery, which can significantly increase the life of the lead-acid battery. The carbon-lead battery combines the lead-acid battery and the supercapacitor into one, which not only takes advantage of the supercapacitor's instantaneous large-capacity charging, but also takes advantage of the lead-acid battery's specific energy. It has very good charging and discharging performance, and because of the addition of carbon, it prevents the negative electrode from sulfating, which improves one of the factors of battery failure in the past and extends the battery life. When in use, although the grid of the carbon-lead battery uses alloy to improve its corrosion resistance, the structural strength of the lead-carbon battery grid is weak, and the connections between the horizontal ribs, vertical ribs and the frame in the grid often fall off or break due to unstable connections, thereby reducing the service life of the grid.
