1 kwi 2024 · Specifically, no signal for K was detected in the pristine electrodes, while the peaks of K 2p 3/2 and K 2p 1/2 appeared after discharge to 0.01 V, corresponding to the generation of K x Se as well as SEI [57].
20 lut 2020 · In this device, the intercalation/deintercalation of Li and Na ions into TiN (battery-like behaviour) can generally contribute 50–60% of the total energy storage, while the adsorption/desorption of electrolyte ions (solvated Cl − or ClO 4−) on the electrode surface
26 mar 2020 · In this work, a comparative study of the implementation of SnO 2 and TiO 2 nanoparticles in combination with carbon-based conductive matrices is carried out in order to enhance battery...
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.
This thesis aims to provide insight into the fundamental electrochemical processes taking place when cycling SnO2in lithium-ion batteries (LIBs). Special attention was paid to the partial reversibility of the tin oxide conversion reaction and how to enhance its reversibility.
With high theoretical capacity, tin phosphide (Sn4P3) has recently garnered attention as the anode for potassium-ion batteries (PIBs). However, its application is limited by the rapid capacity decay, which is highly correlated with the stability of solid electro-lyte interphase (SEI).
