23 cze 2023 · The first charge and discharge curve of the battery prepared by the five samples at a current rate of 0.1C in the potential range of 1.0−3.0 V is shown in Fig. 5c. The curves of W x TNO ( x = 0.02, 0.04, 0.06, 0.08) show a similar shape without an additional obvious platform compared with TNO samples, likely due to that the effect of micro ...
1 cze 2021 · The interfacial characteristics of the electrode were examined using a focused ion beam (FIB, FEI/Helios G3CX) with energy-dispersive spectroscopy (EDS). The assembled batteries were charged at a constant voltage of 6 V for 30 min and discharged at a constant current of 0.01 mA.
13 mar 2020 · Here, by encapsulating nanoparticles of metallic tin in mechanically robust graphene tubes, we show tin anodes with high volumetric and gravimetric capacities, high rate performance, and long...
18 mar 2020 · Tin and tin compounds are perceived as promising next-generation lithium (sodium)-ion batteries anodes because of their high theoretical capacity, low cost and proper working potentials. However, their practical applications are severely hampered by huge volume changes during Li + (Na + ) insertion and extraction processes, which could lead to ...
24 gru 2021 · In this work, we develop a more complete fundamental understanding of the evolution of a tin-foil anode during cycling, shining light upon the mechanisms governing its reversibility and performance. The tin foil was synthesized as follows.
1 paź 2020 · Encouraged by the success of Sony’s 14430 battery (Sn–Co–C anodes), various Sn–Fe–C/Sn–Fe/Sn–C composites were evaluated as the anode for lithium-ion batteries. Compared with Sn–Co–C anodes, Sn–Fe–C alloy with lower price has superior discharge and charge rate capabilities.
28 sie 2017 · To determine the effect of electrolyte salts on the cycling properties of tin anodes in sodium ion batteries, sodium/tin cells were prepared using eight electrolytes containing NaCF 3 SO 3, NaBF 4, NaClO 4, and NaPF 6 in ethylene carbonate-dimethyl carbonate (EC-DMC) and EC-DMC/fluoroethylene carbonate (FEC) solvents.
