Abstract

The invention discloses a nanometer carbon-lead super capacitor battery, which comprises electrodes, wherein the electrodes are made of a carbon nanomaterial and a foam lead composite material; the carbon nanomaterial and the foam lead composite material are prepared by adopting an electrolytic deposition method; and the electrolytic deposition method comprises the following steps: preparing an electrolytic deposition solution; adding a carbon nanomaterial into the electrolytic deposition solution prepared in the step (1); and performing electrolytic deposition to obtain the carbon nanomaterial and the foam lead composite material. According to the nanometer carbon-lead super capacitor battery disclosed by the invention, a lead-acid battery is combined with a super capacitor, so that high energy storage density and high power density are realized simultaneously; high charging and discharging performances are achieved, and the charging speed of the battery is the same as the discharging speed in an unsaturated charging running mode; a carbon material can be used for preventing the phenomenon of sulfation on the cathode, so that a past failure factor of the battery is improved, and the service life of the battery is prolonged; and the nanometer carbon-lead super capacitor battery has very high safety performance, and is an environment-friendly safe battery.

Description

technical field [0001] The invention belongs to the related field of chemical power sources, and in particular relates to a nano-carbon-lead supercapacitor battery. Background technique [0002] Lead-acid batteries are the earliest batteries used in the automotive field. Lead-acid batteries have survived for 150 years. In the decades when new batteries such as nickel-cadmium batteries, nickel-hydrogen batteries, and lithium-ion batteries have been on the market, they can still firmly occupy most of the market share. [0003] Table 1 Performance comparison of lead-acid (SLA) batteries, nickel-cadmium (Ni-Cd) batteries, nickel-hydrogen (Ni-MH) batteries and lithium-ion (Li-ion) batteries. [0004] [0005] As shown in Table 1, the initial voltage of lead-acid batteries is higher than that of traditional nickel-cadmium (Ni-Cd) batteries and nickel-hydrogen (Ni-MH) batteries, while the energy density is lower than that of nickel-cadmium, nickel-hydrogen and lithium batteries...
