Abstract

The invention discloses a carbon-plate negative-plate sealed lead acid battery which comprises positive plates and negative plates, wherein parts of the negative plates are carbon plates, and each of the carbon plates comprises a metal substrate, the mixture of porous carbon materials and graphite materials coated on the metal substrate, and composite materials of the mixture. The invention is based on the principle of super-capacitor interfacial electrochemistry double-electrode layers, adopts the carbon plates with the energy storage of electrochemistry double-electrode layers, and the electrochemistry double-electrode stored energy on the two-phase interface of electrolyte/electrode materials has the characteristics of the performance of super-capacity and the capacity energy storage of batteries. The carbon-plate negative-plate sealed lead acid battery has the advantages of high specific power, rapid large-current discharge, corresponding lower discharge depth of batteries, long process of large-grain lead sulfate crystal accumulation on the negative plates, and long service life of the battery.

Description

technical field [0001] The invention relates to a sealed lead-acid battery with a carbon plate negative plate. Background technique [0002] In today's society, air pollution is becoming more and more serious, and energy resources such as oil are becoming increasingly scarce. It will be a long-term problem for scientific researchers to pay attention to and vigorously develop and research energy sources powered by batteries. Electric bicycles are light, fast, pollution-free, and low-cost means of transportation, and are very popular among consumers. Lead-acid batteries are the main power source for electric bicycles currently on the market due to their abundant resources, low price and good safety performance. [0003] However, as the power source of electric vehicles, lead-acid batteries have low volume specific energy and weight specific energy; low specific power, and cannot be quickly charged and discharged; for the heavy-duty use of electric bicycles, the battery is pro...
