“…The experimental results showed that the cycle reversibility of the battery was improved by increasing the active area of the lead carbon electrode. The research results provided technical support for the recovery and utilization of lead resources (Li et al, 2022). Ma et al repaired and remanufactured the thermal fatigue crack of ductile iron brake disc by laser remelting.…”

Introduction: In the actual engineering operation, there are some components facing high frequency friction, which have high damage rate and poor direct replacement benefit. In order to achieve sustainable resource utilization and more effective component remanufacturing, research was conducted on the cladding layer of friction components.Methods: Based on the idea of remanufacturing, taking 42CrMo as the raw material of engine piston pin hole, laser cladding technology and ultrasonic rolling technology are used to prepare the cladding layers of Fe, Ni and Co three different substrates.Results and Discussion: The experimental results showed that the Co based cladding layer with ultrasonic rolling technology performed best. The surface roughness reduced by 1.02 μm, only 0.14 μm. The microhardness increased by 101.39%, with 795.38 HV. The friction coefficient was 0.051. The friction rate at high temperature decreased by 85.71%, and it was 1.2%. The friction at high temperature was reduced by 79.24%, with 0.9%.Conclusion: Co based cladding layer combined with ultrasonic rolling technology shows the best performance, which can effectively realize the remanufacturing of engine piston pin hole, providing technical reference and data support for the remanufacturing process of high-frequency friction components.

“…Even though rGO performs less than graphene, as regards conductivity and toughness, for instance [67], this new material can be easily mass produced [68]. In recent years, graphene [55,69,70] and multi-walled carbon nanotubes (MWNT) [55,71] were also tested as additives for the negative electrodes. Furthermore, some attempts were made to exploit GO in the LABs electrode.…”

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.
