4-Aminobenzoic acid as a novel electrolyte additive for improved electrochemical performance of Li1.2Ni0.2Mn0.6O2 cathodes via in situ electrochemical polymerization

Determination of the Conformational Preference of para-Aminobenzoic Acid on Vanadium Pentoxide Surface: An XPS and DFT Study

“…Since the experimental values are more similar to the simulation of the up-standing configuration, this is the dominant configuration on the surface. This is also in agreement with the proposed configuration of chemisorbed PABA on TiO 2 and Li 1.2 Ni 0.6 Mn 0.2 O 2 Figure e,f shows the C/V and N/V ratios, also indicating that the up-standing configuration is the more present one in the experiment.…”

“…This is also in agreement with the proposed configuration of chemisorbed PABA on TiO 2 23 and Li 1.2 Ni 0.6 Mn 0.2 O 2 . 19 Figure 7e,7f shows the C/V and N/V ratios, also indicating that the up-standing configuration is the more present one in the experiment. The consideration of angle dependency of the cross section is shown in Figure S5 without contamination.…”

“…In this research, we study the SAM formation of PABA molecules on the surface of V 2 O 5 . Besides their already shown applicability for forming a polymer coating, these kinds of molecules can be used for the link with other molecules to functionalize the surface, due to the reactivity of the terminal amino group. To realize this process, it is necessary to confirm that the SAM configuration has the amino moiety as the topmost layer, as it is, e.g., on anatase (TiO 2 ) surfaces …”

“…Due to additive decomposition prior to solvent oxidation, this is an effective method for upgrading the interfacial stability of layered cathode materials on the battery cycling process. 18 Recently, Zhuang et al 19 studied the coating formation onto Li 1.2 Ni 0.6 Mn 0.2 O 2 using para-aminobenzoic acid (PABA) as an additive. The PABA molecules are adsorbed onto the cathode surface, resulting in a protective PABA polymer coating.…”

Interfacial Degradation and Optimization of Li‐rich Cathode Materials†

“…Zheng et al used 4‐aminobenzoic acid (4‐ABA) as an electrolyte additive to change the interface properties of Li‐rich cathode materials. [ 114 ] 4‐ABA was easily adsorbed on the surface of Li 1.2 Ni 0.2 Mn 0.6 O 2 , and was preferentially oxidized at 4.36 V. Cycled Li 1.2 Ni 0.2 Mn 0.6 O 2 electrodes with and without 4‐ABA additive were tested through XPS. In C 1s and F 1s XPS with 4‐ABA, decomposition products of the original electrolyte reduced, like RCO 3 Li, LiF, ROCO 2 Li and Li x PO y F z .…”
