“…According to Butler-Volmer intercalation kinetics [25] , it's assumed that the lithium atoms firstly fill with the interstitial sites. After all of the interstitial sites are filled with, if the phase is still not stable, lithium atoms go on replacing the metal atoms, during which the crystal structure won't be changed.…”

“…The capacity fade of lithium ion batteries is strongly related to the use conditions, such as the charge and discharge rate, [16][17][18][19] the cut-off voltage, [19][20][21] the depth of discharge (DOD), [22][23][24] the state of charge (SOC) [25][26][27] and the ambient temperature, [28][29][30][31][32][33][34] which all have inuences on the performance and the lifetime of lithium ion batteries. In general, the primary cause of capacity fade is attributed to the loss of active lithium which might result from the generation of solid electrolyte interface (SEI) lm on the anode, the deposition of lithium or electrolyte decomposition.…”

The effects of discharge rates (0.5C, 1.0C, 2.0C, 3.0C, 4.0C and 5.0C) on the aging of LiFePO 4 /graphite full cells are researched by disassembling the fresh and aged full cells. The capacity degradation mechanism is analyzed via electrochemical performance, surface morphologies and compositions, and the structure of the anode and cathode electrodes. The capacity fade is accelerated with increasing discharge rates. The irreversible loss of active lithium due to the generation of an SEI film is the primary aging factor for the full cells cycled at low discharge rates. However, when the discharge rate is greater than or equal to 4.0C, the performance degradation of the LiFePO 4 electrode is distinct due to structure decay, which is caused by quick and repeated intercalation of lithium ions and elevated temperature during discharging.In addition, the SEI film on the anode tends to be unstable after the rapid extraction of lithium ions at high discharge rates, and this enhances the loss of active lithium. Therefore, it is indicated that the degradation mechanism is changed for the full cells aged at 4.0C and 5.0C. Besides, the high discharge rate also increases the internal resistance of the full cell, which is detrimental to high rate discharge performance.

“…In this model, the chemical reaction was simply assumed to transform from reactants to products, while the intermediate product was ignored during the charge/discharge course. According to Butler-Volmer intercalation kinetics [14], lithium atoms first occupy the interstitial sites in a unit cell and then hold the lattice position of metal atoms. In this work, it was supposed that the symmetric structure of intermetallic β-SnSb was not altered during the alloying/ de-alloying process.…”

Based on the first-principles plane wave pseudo-potential method, the electronic structure and electrochemical performance of Li x Sn 4 Sb 4 (x=2, 4, 6, and 8) and Li x Sn 12−x Sb 4 (x=9, 10, 11, and 12) phases were calculated. A Sn−Sb thin film on a Cu foil was also prepared by radio frequency magnetron sputtering. The surface morphology, composition, and lithium intercalation/extraction behavior of the fabricated film were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and cyclic voltammetry (CV). Lithium atoms can easily insert into and extract out of the β-SnSb cell due to the low lithium intercalation formation energy. It is found that lithium atoms first occupy the interstitial sites, and then Sn atoms at the lattice positions are replaced by excessive lithium. The dissociative Sn atoms continue to produce different Li-Sn phases, which will affect the electrode stability and lead to the undesirable effect due to their large volume expansion ratio. The calculated lithium intercalation potential is stable at about 0.7 V, which is consistent with the experimental result.
