Lead-carbon battery is a kind of new capacitive lead-acid battery, which is based on the traditional lead-acid battery, using the method of adding carbon material to the negative electrode to improve the specific capacity and charge-discharge characteristics of the battery. Lead-carbon battery solves the defects of low charge-discharge rate of traditional lead-acid battery, improves the phenomenon of negative sulfate, and has the advantages of good charge-discharge performance and long battery life. This paper firstly starts from the principle and structure of lead-carbon battery, then summarizes the research progress of lead-carbon battery in recent years, and finally looks forward to the development direction and trend of lead-carbon battery in the future.

The six cells of the dynamic lead acid battery (DLAB) series have been made to resemble the accumulator with sulfuric acid single electrolyte. The tank was filled with 1200 mL of 30% sulfuric acid and circulated through each unit cell by a minipump during charge-discharge process. Experiments were carried out by providing a charging current of 2A, while the discharge current was varied at 0.5 A, 0.6 A, 0.7 A, 0.8 A for 10 continuous cycle to obtain the battery with the best characteristics. The experimental results show that all batteries have a working voltage of 10.8-14.4 volt. The discharging current is inversely proportional to the discharging duration. The resulting capacity has an efficiency ranging from 80.1-81.1%. DLAB with 0.5 A discharging current shows the best performance based on the length of duration and the average capacity with value of 109.61 h and 6168 mAh while for the ideal performance stability is obtained by DLAB with 0.7 A discharging current. The electrochemical reaction produces angelsite and plattnerite phases on the positive electrode. Meanwhile, angelsite and lead phases are formed on the negative electrode.

“…To address these issues, many additives to the negative and the positive electrodes have been proposed [3,4]. In addition, additives to the electrolyte [5] are considered as prospective for improving the performance of lead-batteries. The use of additives in the active materials or the electrolyte has been fairly well studied in the literature, but there is limited data for the application of external radiation which exert an influence on the chemical and electrochemical processes that take place in the lead battery.…”

During the operation of the negative electrode, some critical processes take place, which are limiting factors for the operation of lead–acid batteries. To improve the efficiency of the negative active material and minimize these processes, external application of multivector field is proposed. Two applications of the multivector field are studied: during negative paste preparation and during formation. It is established that, when applying multivector field during negative paste preparation, the chemical processes proceed more efficiently. The results are better phase composition and crystallinity of the cured paste, thus increasing the capacity of the consequently built lead batteries by 12% on average. The application of a multivector field during the formation of negative active materials in lead batteries has a positive effect on the skeletal structure, the size and shape of the Pb crystals. This ensures longer service life, which is confirmed by the 17.5% Depth of Discharge continuous tests on 12 V/75 Ah batteries. The batteries formed under the influence of external multivector field showed 20% longer cycle life. Based on the experimental result, a most probable mechanism of the influence of the multivector field on the chemical and electrochemical processes in lead batteries during negative paste preparation and formation of negative active masses is proposed.
