Progress in Natural Science:Materials International 2023年第3期33卷 320-327页

Ltd. College of Chemical Engineering and Light Industry Guangdong University of Technology

LiNi0.6Co0.2Mn0.2O2//graphite full cell, due to its high energy density as the most promising candidate for power batteries received increased attention, but the severe capacity loss under high-temperature conditions prevents their large-scale application. Here, glutaric anhydride（GA） and succinic anhydride（SA） as electrolyte additives are investigated to overcome the high-temperature problem of LiNi0.6Co0.2Mn0.2O2//graphite cells. Due to the unique film-forming features and high-temperature stability, the cells containing 0.5% GA and 0.5% SA can retain capacity retention of 91.2% and 92.4% stored at 60°C for 15 days, corresponding to a negligible capacity loss of 4.6 and 0.8 m Ah g-1after 200 cycles, respectively. In addition, the lifespans of cells under 25°C are also significantly extended by introducing GA and SA into the electrolytes. Electrochemical and spectroscopic techniques results indicate the full cell capacity loss is predominantly caused by the unstable anode solid electrolyte interphase（SEI） layer and a stable SEI film derived from GA and SA is formed on the graphite electrode *** SEI film can effectively inhibit the consumption of electrolytes and enhance the high-temperature performance of cells. This work paves a way for moderating high energy density cells' work under high-temperature operation by developing special anodic film-forming electrolyte additives.

An improved simulation of temperature field in Laser–low current MAG of thin galvanized steel sheets

This study aimed to achieve efficient and precise connection of thin steel sheets for vehicles by analyzing the thermal process of Laser-MAG hybrid high-speed welding lap of thin galvanized steel sheets. A high-speed camera combined with an NI AD data acquisition system were used, and the transition behavior and electrical signals of low-current MAG and Laser-MAG hybrid welding were examined. The thin sheet MAG welding droplet transition method mainly comprised short-circuit transfer. During the short-circuit phase, the voltage decreased and the current increased sharply, forming a short-circuit liquid column. When current increased to a certain level, the liquid bridge burst, the droplets carried heat and kinetic energy to the weld pool, the arc voltage returned to a no-load state, and the arc was re-ignited. In the arcing phase, the current first decreased steeply and then slowly, while the voltage decreased slowly and smoothly. According to the different heat source characteristics of the arc combustion and short-circuit stages during short-circuit transition, a new MAG heat source for low-current short-circuit transition was developed. This study employed a double-ellipse heat source with different powers for the arc combustion stage as well as a uniform body heat source that considered the thermal and kinetic energies of the melt droplets for the short-circuit stage. The thermal input of low current MAG welding was described by double-ellipse and uniform body heat source periodic loading. Moreover, the laser exerted an attraction and compression influence over the arc during the hybrid welding, which promoted the droplet transfer. Therefore, based on the novel MAG heat source, a hybrid Laser-MAG heat source in the short-circuit transition mode was developed. The laser beam heat source was described using a three-dimensional column heat source, the arc attraction and compression by the laser were considered indirectly through distribution parameter tuning for th
