Constructing inorganic-rich solid electrolyte interphase via abundant anionic solvation sheath in commercial carbonate electrolytes

Self-Assembly Monolayer Inspired Stable Artificial Solid Electrolyte Interphase Design for Next-Generation Lithium Metal Batteries

“…From the above XPS analysis, Figure S4 and literature results, − we illustrated the SEI structures of the MPDMS-dipped Li anode and blank Li anode in Figure e,d, respectively. Overall, our results showed that the MPDMS molecule can bind to the Li anode through its mercapto group to form a uniform and strong protective layer, where the inorganic-rich artificial SEI is beneficial for the cyclability of Li metal anodes, consistent with literature results. , …”

“…Overall, our results showed that the MPDMS molecule can bind to the Li anode through its mercapto group to form a uniform and strong protective layer, where the inorganic-rich artificial SEI is beneficial for the cyclability of Li metal anodes, consistent with literature results. 57,58 To further verify the potential application and feasibility of MPDMS in practical batteries, the MPDMS-10 anode was paired with both LiFePO 4 (LFP, 7 mg cm −2 , ∼1.1 mAh cm −2 ) and LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) cathodes (6.5 mg cm −2 , ∼1.2 mAh cm −2 ) to assemble Li metal based coin cells. The cells with MPDMS-10 anodes exhibits better cycling stability compared to the blank Li anodes.…”

Amide‐Functional, Li3N/LiF‐Rich Heterostructured Electrode Electrolyte Interphases for 4.6 V Li||LiCoO2 Batteries

“…[33] Li 3 N in CEI from 3-TPIC has high ionic conductivity, which is of great significance for high-quality CEI. [34] Moreover, Li 3 N with gradient distribution (1.33%, 1.2%, and 0.51%, corresponding to 0 min, 2 min, and 4 min respectively) contained in CEI can form heterostructure with LiF, which is helpful for lithium-ion adsorption and Li + transport. [35] Notably, the contents of polar amide group in the CEI with 4-TPIC are more than that with 2-TPIC (Figure S4b,e, Supporting Information).…”

Engineering Electrode/Electrolyte Interphase Chemistry toward High-Rate and Long-Life Potassium Ion Full-Cell

“…Furthermore, the activation energies of the processes F4 and F3 at about 4.5 V were calculated according to eq 3 in the Supporting Information (the measured temperatures are 298.15, 303.15, 308.15, 313.15, and 318.15 K). Figure g shows the temperature-dependency of 1/ R ct , and the activation energies correspond to the graph slopes . Clearly, it can be seen that the activation energies of R ct for KFeHCF (4.5 V)/Gr (0.01 V) are 30.6 kJ mol –1 (process F4) and 31.5 kJ mol –1 (process F3), which are smaller than those calculated for KFeHCF (2.0 V)/Gr (3.0 V) (32.9 kJ mol –1 for process F4 and 35.0 kJ mol –1 for process F3).…”

“…Figure 3g shows the temperature-dependency of 1/R ct , and the activation energies correspond to the graph slopes. 42 Clearly, it can be seen that the activation energies of R ct for KFeHCF (4.5 V)/ Gr (0.01 V) are 30.6 kJ mol −1 (process F4) and 31.5 kJ mol −1 (process F3), which are smaller than those calculated for KFeHCF (2.0 V)/Gr (3.0 V) (32.9 kJ mol −1 for process F4 and 35.0 kJ mol −1 for process F3). The lower activation energy of the former agreed well with the in situ EIS results and determined the ability of fast charge transfer and thus facilitated K + insertion into graphite.…”
