“…In general, the relationship between the electrochemical process and carbon materials was estimated using the I D / I G ratio . Owing to the abnormal increase of the I D / I G ratio as the pyrolysis temperature increases for some nitrogen-doped carbon materials, the I D / I G ratio may not be accurate to evaluate the textures of carbon. − Herein, we plot the curves of capacity retention versus the I D / I G ratio. Unfortunately, both the cyclic capacity retention (Figure e, Figure S18c, d) and the rate capacity retention (Figure f) deliver a weak correlation to the I D / I G ratio.…”

The rechargeable aqueous zinc–iodine (Zn–I2) battery has emerged as a promising electrochemical energy storage technology. However, poor cycling stability caused by the dissolution of iodine species into the electrolyte limited its practical application. Herein, we report a nitrogen-doped porous carbon (NPC) material in gram scales. Performed as an iodine host in the Zn–I2 battery, the NPC shows a high specific capacity (345.3 mAh g–1 at 0.2 C), superior rate capability (53.2% capacity retention at 10 C), and remarkable cycling stability (10 000 cycles at 10 C with a capacity retention of 80.9%). More importantly, DFT computations reveal that the graphitic-N (N-Q) exhibits the strongest adsorption of iodine; however, pyridinic-N (N-6) shows the weakest adsorption of iodine. Moreover, the N-6/N-Q ratio is an essential parameter that significantly determined the electrochemical performance of Zn–I2 batteries. Therefore, the improved long-term cycling stability and rate capability of the as-designed Zn–I2 battery are attributable to the decrease of the N-6/N-Q ratio. This work is of great significance for devolving highly reversible Zn–I2 batteries.

“…Figure 1a expresses the XRD patterns of three CWB samples prepared at different carbonization temperatures. All samples showed two broad peaks located at approximately 25 and 44°, corresponding to the (002) and (100) planes of amorphous carbon, 24,25 while the (100) diffraction peak of CWB-1000 became sharp, indicating the existence of graphitization carbon at high temperature. 26 The XRD pattern in Figure S3a verified the pure graphite phase of the commercial product.…”

Graphite is the mainstream anode material of commercial lithium-ion batteries, while its low theoretical capacity and short supply limit its application in the ever-increasing demand for high-capacity batteries. For carbonaceous anode materials, the small surface area can endow relatively high initial Coulombic efficiency, and large mechanical strength can endow good stability during long-term cycling. In this study, sustainable wheat bran was utilized to prepare cost-efficient carbon anode via carbonization. At the reaction temperature of 800 °C, the carbonized wheat bran displayed an optimal mixed phase of ordered graphite (provided high conductivity) and amorphous carbon (provided more active sites). Due to a distinctive honeycomb-shaped hexagon structure and a small surface area of 57 m2 g–1, the as-prepared carbon material could achieve initial Coulombic efficiency up to 85%. Such an anode material revealed a superior reversible capacity of 515 mAh g–1 and corresponding retention of 92% after 1000 charge/discharge cycles. Using LiNi0.5Co0.2Mn0.3O2 as the cathode, the full cell delivered a large areal capacity of 2.66 mAh cm–2 over 200 cycles, with a high cycling stability of 82%. With such high Coulombic efficiency, areal capacity, and capacity retention, the carbonized wheat bran is on par with state-of-the-art carbonaceous anode material. This work develops a scalable and effective strategy to synthesize high-performance and low-cost carbon anode.
