“…The electrochemical characteristics of special valve-controlled lead-carbon batteries for mining use are the same as those of ordinary explosion-proof special lead-acid batteries, and they follow the design and inspection standards for explosion-proof lead-acid batteries in China. The design structure and materials are different from ordinary lead-acid batteries, using carbon-based functional materials, graphene composite plate technology, and horizontal bipolar ear plate technology [3]. Compared to ordinary lead-acid batteries, they have capacitive characteristics.…”

As a power source, ordinary explosion-proof large-capacity lead-acid batteries have been widely used in underground explosion-proof lead-acid battery scrapers and support trucks, but there are some problems, such as too long charging time, the need to manually add distilled water regularly, and the inability to realize intelligent management. In this paper, the mine special valve-regulated lead-carbon lead-acid battery with capacitance characteristics is applied to the explosion-proof heavy-duty electric drive car, which can shorten the charging time to about 1/5 of that of the ordinary lead-acid battery and reduce the labor maintenance cost. Through multi-sensor fusion technology, an online monitoring and intelligent expert management system for the explosion-proof battery is constructed, which can remotely monitor the real-time state of the battery. It can find out the causes of battery failure, give an alarm in advance, and prolong the service life of the battery pack, which is conducive to the further popularization and use of underground electric-driven trackless rubber tires.

“…On the other hand, they are outperformed by Li-ion batteries (LIBs) when it comes to weight, since their specific energy is limited to 30-40 Whkg −1 [4,5], while LIBs can be manufactured with a specific energy up to 250 Whkg −1 [6]. LABs also suffer from a cycle life limited to 500 cycles, which dramatically drops when they are operated at a partial state of charge [7][8][9][10]. These poor performances, in conjunction with the fact that LABs can operate at a maximum rate of C/5, drastically limit their application in hybrid electrical vehicles and even in renewable energies applications [1,[11][12][13][14][15].…”

Nanostructured Lead Electrodes with Reduced Graphene Oxide for High-Performance Lead–Acid Batteries

et al. 2022

Nanostructured Pb electrodes consisting of nanowire arrays were obtained by electrodeposition, to be used as negative electrodes for lead–acid batteries. Reduced graphene oxide was added to improve their performances. This was achieved via the electrochemical reduction of graphene oxide directly on the surface of nanowire arrays. The electrodes with and without reduced graphene oxide were tested in a 5 M sulfuric acid solution using a commercial pasted positive plate and an absorbed glass mat separator in a zero-gap configuration. The electrodes were tested in deep cycling conditions with a very low cut-off potential. Charge–discharge tests were performed at 5C. The electrode with reduced graphene oxide outperformed the electrode without reduced graphene oxide, as it was able to work with a very high utilization of active mass and efficiency. A specific capacity of 258 mAhg−1–very close to the theoretical one–was achieved, and the electrode lasted for more than 1000 cycles. On the other hand, the electrode without reduced graphene oxide achieved a capacity close to 230 mAhg−1, which corresponds to a 90% of utilization of active mass.
