Morphology Variations in Copper Sulfide Nanostructures as Anode Materials for Na-Ion Capacitors

“…1−3 Among these, the Na-ion-based EESDs have been paid so much attention as they provide comparable performance with lithium-ion (Li + ) based EESDs. 4 However, many challenges to improve the cyclic stability, efficiency, and capacity of the Na-ion capacitors (NICs) remain. 5 The unearthing of appropriate anode materials for storing Na + ions during electrochemical reactions is a significant concern.…”

“…The rapid development of renewable energy storage and electric vehicles has triggered a strong demand for low-cost energy storage technologies. − Among various electrochemical energy storage devices, lithium ion batteries (LIBs) exhibits more higher energy density and longer cycle life as well as lower self-discharge rate. , However, the shortage of lithium resources (only 0.0017 wt % in the Earth’s crust) and the soaring price of battery-grade lithium carbonate salt have caused an increase in the overall production cost of LIBs, thereby further hindering the wide-scale application of LIBs. ,− Fortunately, sodium ion batteries (SIBs) with similar physicochemical properties to LIBs possess lower production costs, compared to LIBs by virtue of the bountiful reserves of sodium resource in the Earth’s crust (2.75 wt %), demonstrating their broad application prospects in large-scale energy storage and electric vehicles field. − More importantly, the element Na possesses a redox potential (−2.71 V vs SHE) similar to that of lithium (−3.04 V vs SHE) . However, graphite, a commercialized anode material for LIBs, exhibits low capacity in SIBs due to the high transition energy required for Na + migration between graphite layers. ,, Moreover, the large Na + radius (1.02 Å) will give rise to the sluggish Na + diffusion kinetics and large volumetric changes of materials during the sodiation and desodiation processes. , Therefore, it is essential to develop a suitable anode material for SIBs with low insertion/extraction potential, large discharge capacity, and long cycle life.…”

Breaking Barriers: Binder-Assisted NiS/NiS2 Heterostructure Anode with High Initial Coulombic Efficiency for Advanced Sodium-Ion Batteries

“…On the other hand, the development of alternative energy storage devices has come into focus. , Developing low-cost and environment-friendly energy storage devices is crucial for utilizing and exploiting clean energy sources. Among them, sodium-ion batteries (SIBs) are considered up-and-coming energy storage devices for the future due to the abundance of sodium resources in the earth’s crust and oceans as well as their low cost. − The chemical mechanism of SIBs is similar to LIBs, but the developments of suitable anode materials with the capability of accommodating large sodium ions are highly desirable. , Moreover, the large volume expansion during charging and discharging in SIBs, low ICE, and low energy density, alongside the formation of the solid-electrolyte (SEI) film on the electrode surface, severely undermine the electrode integrity. − Designing the electrode material is the key factor in controlling the volume expansion and enhancing the sodium-ion diffusion within the electrode. Furthermore, huge mass expansion and structural evolution during ion insertion/extraction hinder the practical application of SIBs.…”
