Effects of lithium content on the electrochemical lithium intercalation reaction into LiNiO2 and LiCoO2 electrodes

The film growth and electrochemical properties of rf-sputtered LiCoO2 thin films

“…There are several methods to evaluate the D Li + like PITT [18,19,25], GITT [20][21][22], EIS [22,23,25], and SSCV [24,25]. The D Li + values determined by various methods show significant discrepancies due to the limitations involved in each measurement.…”

Electrochemical kinetics study of Li-ion in Cu6Sn5 electrode of lithium batteries by PITT and EIS

“…In the composite electrode, the electrolyte can permeate through the additives (carbon and binder) and the determination of the actual electrochemically active surface area is nearly impossible. Therefore, from the available literature, it can be seen that both the geometric surface area of the electrode [32][33][34][35] and the actual surface area of the active material (mostly obtained from BET method) [36,37] have often been used for the D Li calculation. Here we used the geometric surface area of the electrode to calculate the D Li .…”

Studies on the effect of titanium addition on LiCoO2

“…If lithium is used as the counter electrode, all the active material from LiCoO 2 is removed and peaks appear during the forward scan 3.92 V, while in the reverse sweep, the peak appears at 3.89 V, respectively, and these peaks are first-order phase transitions. This is mainly due to the lithium deintercalation/intercalation into the intercalation sites, which is due to two pseudo-phases of lithium dilute α-phase and lithium concentrated β-phase [21]. The second and third sets of peaks are observed at (4.055, 4.060) and (4.174, 4.164 V), respectively.…”
