Problems solved by technology

[0002] Road electric vehicles are vehicles powered by batteries. Vehicles that use batteries as power sources are called pure electric vehicles (EVs). Vehicles that use batteries as power sources part of the time and fuel engines for parts of the time are called hybrid electric vehicles (HEVs). At present, there are many trial lithium batteries and nickel-metal hydride batteries for electric vehicles, but lithium batteries and nickel-metal hydride batteries are expensive, the technology is immature, and safety issues have not been completely resolved. Moreover, the electrode materials of these two batteries are quite short, so their development space is very large. Limited; at present, lead-acid batteries are also used as power sources for electric vehicles, but the current lead-acid batteries cannot well meet the requirements of electric vehicles for discharge current, discharge time and cycle times

Abstract

The invention discloses a lead-acid battery. The lead-acid battery comprises a positive pole plate and a negative pole plate which are prepared by coating positive pole plate lead plaster and negative pole plate lead plaster on a positive pole plate grid and a negative pole plate grid respectively, and performing curing and formation processes; the positive pole plate grid is casted by the following Pb-Ca-Sn-Al alloy materials in percentage by weight: 1.45 to 1.55 percent of Sn, 0.06 to 0.08 percent of Ca, 0.02 to 0.04 percent of Al, and the balance of Pb and inevitable impurities; and the negative pole plate grid is casted by the following Pb-Ca-Sn-Al alloy materials in percentage by weight: 0.25 to 0.35 percent of Sn, 0.07 to 0.09 percent of Ca, 0.02 to 0.04 percent of Al, and the balance of Pb and inevitable impurities. The lead-acid battery is particularly suitable to be used as the power supply of a road electric vehicle.
