The invention discloses a negative electrode plate of a high-rate and high-power battery capacitor. The negative electrode plate comprises a current collector and an electrode material coating at least one part of area of the current collector, wherein the current collector is a corrosive aluminum foil; the corrosive aluminum foil is obtained through corrosion of at least one part of area of the surface thereof; the electrode material is obtained by mixing an active material, a conductive agent and a binder evenly and pressing a mixture; and the active material is a composite material of one or a mixture of more of graphite, carbon nanotubes, activated carbon, coke, mesocarbon microbeads, hard carbon and soft carbon. The substances of the electrode material of an electrode disclosed by the invention are good in bondability and are not easy to strip, the service life is prolonged, the negative electrode plate has a relatively low potential platform and the average working voltage of a hybrid capacitor battery is higher than that of a traditional double electric layer capacitor, so that the energy density of a system is improved.
