“…Figure 7 shows the EIS measurement of the HSNC and NC samples after 100 cycles with a current density of 0.2 A•g −1 . The Nyquist plots of the HSNC and NC samples in Figure 7a are composed of a semicircle and sloped line, which were associated with the charge-transfer resistance (R ct ) and Warburg resistance (W o ) for the diffusion of Li + ions, respectively [42]. After fitting with an equivalent circuit, the simulated data were obtained (Table S3).…”

Doping heteroatoms such as nitrogen (N) and boron (B) into the framework of carbon materials is one of the most efficient methods to improve the electrical performance of carbon-based electrodes. In this study, N-doped carbon has been facilely synthesized using a ZIF-8/polydopamine precursor. The polyhedral structure of ZIF-8 and the effective surface-coating capability of dopamine enabled the formation of N-doped carbon with a hollow structure. The ZIF-8 polyhedron served as a sacrificial template for hollow structures, and dopamine participated as a donor of the nitrogen element. When compared to ZIF-8-derived carbon, the HSNC electrode showed an improved reversible capacity of approximately 1398 mAh·g−1 after 100 cycles, with excellent cycling retention at a voltage range of 0.01 to 3.0 V using a current density of 0.1 A·g−1.

“…Thirdly, the proper selection of electrolyte additives has a strong impact on the properties of SEI, which can further influence the diffusion of lithium ions through the interface. [365] An ideal SEI for high-rate LIBs with long cyclic life needs to be compact and thin, and enriched with domains with high ionic conductivity. Ideally, it is recommended to create an artificial interfacial layer with several types of functional groups which -developing a low-temperature synthesis route for active materials with a certain ratio of individual metallic elements [307], [305] vanadium oxide -high capacity -tuneable atomic structures and chemical properties -irreversible phase transformation when discharged below 1.9 V -applying vanadium oxide as an additive into other active materials (such as lithium manganese oxide) to improve the overall capacity of the cathode [332], [334] MOFs and their derivatives (cathode)…”

“…Unfortunately, this approach requires intensive effort [6][7][8]. In contrast, merely mixing ZnO with conductive carbonaceous materials [8,9], such as commercially available artificial graphite, can be considered the easiest and simplest method to overcome these disadvantages, thereby providing satisfactory performance. Based on synthesis perspective, homogeneous ZnO particles are easily obtained by simple deposition of a solution containing zinc ions followed by precipitate thermal decomposition.…”

Zinc oxide (ZnO) is one of the most promising materials applied in Li-ion batteries. In this research, ZnO was synthesized by the thermal decomposition of zinc oxalate dihydrate. This precursor was obtained from the precipitation process of zinc sulfate with oxalic acid. In-depth studies were carried out on the effect of various heating temperatures of zinc oxalate dihydrate precursors on ZnO synthesis. The as-prepared materials were characterized by XRD, SEM, and FTIR. Based on the XRD analysis, the presence of the ZnO-wurtzite phase can be confirmed in samples heated at temperatures above 400 °C. Meanwhile, SEM-EDX results showed that the ZnO particles have a micron size. Cells with ZnO samples as anodes have low columbic efficiency. In contrast, cells with ZnO/Graphite composite anodes have a relatively large capacity compared to pure graphite anodes. Overall, based on the consideration of the characterization results and electrochemical performance, the optimal sintering temperature to obtain ZnO is 600 °C with a cell discharge capacity of ZnO anode and in the form of graphite composites is 356 mAh/g and 450 mAh/g, respectively. This suggests that ZnO can be used as an anode material and an additive component to improve commercial graphite anodes’ electrochemical performance.
