“…The table clearly shows that the present work stands out, delivering reasonable energy density and similar operating voltages as compared with literature reports. [ 44–51 ] Moreover, the cycling performance of the full cell is shown in Figure 7d, and the full cell delivered a reversible capacity of 203.3 mAh g −1 having 51.8% capacity retention at 500 mA g −1 even after extensive cycling of 1000 cycles (a low fading rate of 0.049% per cycle). The Coulombic efficiency of the initial cycle was obtained to be 85%; after that, it reaches 98% of the sixth cycle and the remaining cycles follow as 99–100%.…”

Sulfur doping in carbonaceous materials is an effective approach to improve the performance of Li‐ion batteries (LIBs). Herein, sulfur‐implanted carbon dots‐embedded graphene (S‐CDs/rGO) as an anode material for LIBs is reported. A facile method is used to prepare S‐CDs/rGO by annealing the mixture of benzyl disulfide (BDS) and graphene oxide (GO). Herein, BDS serves as both the sulfur source and precursor of CDs. S‐CDs/rGO as an anode material for LIB delivers initial specific capacities of 938.8 mAh g−1 (first cycle) and 598.6 mAh g−1 (second cycle) at a current density of 100 mA g−1. S‐CDs/rGO exhibits superior cycling performance with good capacity retentions of 78.8% (500 cycles), 61.5% (2000 cycles), and 75.7% (2000 cycles) at higher current densities of 1000, 2000, and 3000 mA g−1, respectively. Moreover, the full cell assembly of the prepared S‐CDs/rGO as an anode and commercial LiFePO4 as a cathode in the voltage range of 1.5–3.9 V delivers a high reversible capacity of 203.3 mAh g−1 after extensive 1000 cycles at 500 mA g−1 with 51.8% retention (a low fading rate of 0.049% per cycle), rendering it as a promising anode material for application in high‐performance LIBs.

Molybdenum trioxide (MoO3) shows promise as an anode material for Li/Na-ion batteries due to its low cost and high capacity. However, it suffers from poor cycling stability and volume expansion during charging and discharging, which affects its performance. To overcome these issues, researchers have developed a unique hybrid composite by coating MoO3 nanorods with TiO2, creating MoO3@TiO2 core–shell nanorods. The TiO2 coating significantly improves the composite’s cycling stability, rate capability, and overall electrochemical performance in Li/Na-ion batteries. The optimized electrode (MoO3@TiO2-2) achieves an impressive capacity of 1259.4 mA h g–1 after 500 cycles at 200 mA g–1 and a discharge capacity of 693.3 mA h g–1 after 1000 cycles at 2000 mA g–1 in lithium-ion batteries. In sodium-ion batteries, they show high reversible discharge capacities of 499.1 and 389.3 mA h g–1 after 500 cycles at 100 and 200 mA g–1, respectively. Moreover, even after 1200 cycles at 2 A g–1, the electrode retains a capacity of 300.2 mA h g–1. When combined with an NMC811 cathode in a full-cell Li-ion battery, the composite exhibits excellent cycling performance, lasting over 150 cycles with a capacity of 200 mA h g–1. This research has significant implications for the development of high-performance rechargeable batteries for various electrochemical energy applications.
