Symmetrical Cell for Electrochemical AC Impedance Studies of Lithium Intercalation into Graphite

Impedance Spectra of Energy-Storage Electrodes Obtained with Commercial Three-Electrode Cells: Some Sources of Measurement Artefacts

“…Artefacts of 3-electrode impedance measurements in Li-ion cells are similar to those observed in solid-oxide fuel cells. These were both observed experimentally and computed theoretically, using a finite-element method to model typical geometric misalignments and frequency mismatches between Libattery electrodes in symmetric, half-and full cells [8,[18][19][20][21][22].…”

The cooperative effect of tri(β-chloromethyl) phosphate and cyclohexyl benzene on lithium ion batteries

“…AC impedance spectra of graphite electrode after 50 circles. impedance related to a combined effect of the diffusion of lithium ions on the electrode-electrolyte interfaces, which corresponds to the straight sloping line at low frequency end [16][17][18][19][20]. From the figure, we can know that with increase of the content of the additives the R f is almost same, while the R s and R ct of the battery increase gradually when the batteries all contain additives CHB and TCEP, which may lead to the acceleration of the battery capacity decrease.…”

In Situ Formation of a Cathode–Electrolyte Interface with Enhanced Stability by Titanium Substitution for High Voltage Spinel Lithium‐Ion Batteries

“…[ 45 ] Therefore, two pairs of full cells (LNMO/graphite or LNMTO/ graphite) with identical material loadings were cycled under identical cycling conditions (two cycles at 30 °C, followed by three cycles at 45 °C). Their individual charging/discharging capacities are shown in Figure S6 (Supporting Information).…”
