5 cze 2015 · Tin is one of most promising SIB anode materials, which alloys with up to 3.75 Na, leading to a charge storage capacity of 847 mAh g –1.
28 sie 2017 · At a current rate of 1694 mA g−1 electrode, at the end of 1400th cycle, capacity is about 45 mAh g−1 electrode. The results of the study clearly indicate that the electrolyte salts critically affect the electrochemical performance of the tin anode in sodium ion batteries.
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 · In this review, recent progress and understanding of tin and tin compounds used in lithium (sodium)-ion batteries have been summarized and related approaches to optimize electrochemical performance are also pointed out.
15 kwi 2015 · With VO 2 + /VO 2+ couple as positive part, the Sn–V battery could work steadily at the current density of 180 mA cm −2, the average columbic, energy and voltage efficiencies were 96%, 70% and 72% respectively after 150 cycles of charge and discharge.
26 lut 2022 · Dual-ion battery (DIB) can potentially provide higher power, lower cost and faster charging capability than traditional lithium-ion batteries. Even though graphite can effectively accommodate anions as a cathode for DIB, the high working voltage of around 5 V vs. Li/Li+ leads to continuous side reactions, yielding to low Coulombic efficiency ...
23 cze 2023 · To solve this problem, TiNb 2 O 7 with W 6+ doping was synthesized by a convenient solid-state method. The doping of W 6+ will lead to arranging cation mixing and charge compensation. The cation rearrangement creates a new Li-conductive environment for lithiation, resulting in a low-energy barrier and the fast Li + storage/diffusion.
