Summary: Surface area and conductivity are important factors for hard carbon anodes in sodium-ion batteries. Pine needle derived bulk and micro/nanostructured hard carbons were obtained through different treatments, with the latter showing higher capacity due to nanopores for Na-ion storage. Further enhancement of performance was achieved by rGO coating and high temperature annealing, leading to improved capacity, rate performance, and long-term stability. The micro/nanostructure hard carbon coated with rGO is considered a suitable anode material for SIBs due to its improved performance and renewable advantages.

Summary: In this study, CuS microspheres assembled by single/poly crystalline nanoflakes were successfully synthesized and their sodium ion storage abilities were tested. The results showed that the CuS microspheres assembled by single-crystalline flakes exhibited superior electrochemical performance due to their highly ordered crystal lattice and complete structure integrity. Compared with poly-crystalline structure, the single-crystalline flakes showed an enhanced diffusion rate of sodium ion, leading to excellent rate performance. The structural integrity of the single-crystalline flakes also resulted in high mechanical strength and long cycling stability for CuS microspheres.

Summary: Metal selenides, such as hexagonal FeNi2Se4@C nanoflakes, are promising anode materials for sodium-ion batteries due to their high reversible capacity and initial efficiency. The sodium storage mechanism involves the reversible generation and distribution of Fe and Ni nanoparticles in Na2Se matrix during discharge, and the reversible formation of FeNi2Se4 phase during charge. The excellent electrochemical performance of FeNi2Se4@C nanoflakes is attributed to the reversible phase conversion during cycling.

Summary: The impact of the operating potential window of WS2 electrodes during charge-discharge in Na and K-ion batteries was investigated, revealing that restricting the upper cut-off potential to 2.0 V resulted in better electrochemical performance. Additionally, kinetic analysis showed that K-ion storage in WS2 electrodes is diffusion dominated, while Na-ion storage is pseudo-capacitive in nature.
