“…The LAND battery instrument (Wuhan Kingnuo Electronic Co., Wuhan, China) was used to conduct the constant current charge and discharge test and galvanostatic intermittent titration technique (GITT) test. The cyclic voltammetry test (CV, scanning speed 0.1-1 mV s −1 ) was measured in an electrochemical workstation (CHI660E) with a voltage window of 0.005-2 V. The apparent diffusion coefficients of Na + in the electrode were measured by GITT [37]. The ratio of capacitance drive and diffusion process to total capacity was calculated [79].…”

“…), have been explored for NIBs [28][29][30][31][32][33][34][35][36]. Alloy materials have been widely concerned by researchers because of their high specific capacity of sodium storage, relatively high reaction potential, and high conductivity [37][38][39]. However, the poor reaction kinetics of alloy materials, huge volume changes, and irreversible structural deterioration in the process of sodium intercalation and desalination lead to pulverization of materials and rapid attenuation of specific capacity, which limit the application of alloy materials [40,41].…”

Anode materials have a vital influence on the performance of sodium ion batteries. In this paper, SnSb nanoparticles were distributed uniformly in N-doped three-dimensional porous carbon (SnSb@N-PC), which effectively avoided the agglomeration of alloy nanoparticles and greatly improved the capacity retention rate of SnSb@N-PC. At the same time, the porous carbon substrate brings higher conductivity, larger specific surface area, and more sodium storage sites, which makes the material obtain excellent sodium storage properties. The first discharge-specific capacity of SnSb@N-PC was 846.3 mAh g−1 at the current density of 0.1 A g−1, and the specific capacity remained at 483 mAh g−1 after 100 cycles. Meanwhile, the specific capacity of SnSb@N-PC was kept at 323 mAh g−1 after 400 cycles at a high current density of 1.5 A g−1, which indicated that the recombination of SnSb with porous carbon played a key role in the electrochemical performance of SnSb. The contribution of capacitance contrast capacity was able to reach more than 90% by the cyclic voltammetry (CV) test at high sweep speed, and larger Na+ diffusivity was obtained by the constant current intermittent titration technique (GITT) test, which explains the good rate performance of SnSb@N-PC.

“…However, the growing trend of Hybrid lithium-ion capacitors is seriously impeded due to rising lithium resources price and the low geographical limitation [15][16][17][18][19]. Therefore, metal-ion capacitors composed of abundant elements, in other words, new-type energy storage devices, including sodium [20][21][22][23][24], potassium [6,[25][26][27]] magnesium [28][29][30][31], aluminum [15,[28][29][30][31][32][33][34][35] and zinc [36][37][38][39], are essential for alternatives to HLICs. It is well established that sodium is similar to lithium in chemical properties, indicating the experience obtained from the HLICs researches can be applied to hybrid sodium ion capacitors [40][41][42].…”

The development of electrochemical energy storage devices has a decisive impact on clean renewable energy. Herein, novel ultrafast rechargeable hybrid sodium dual-ion capacitors (HSDICs) were designed by using ultrathin carbon film (UCF) as the cathode material. The UCF is synthesized by a simple low temperature catalytic route followed by an acid leaching process. UCF owns a large adsorption interface and number of additional active sites, which is due to the nitrogen doping. In addition, there exists several short-range order carbons on the surface of UCF, which are beneficial for anionic storage. An ultrafast rechargeable remarkable performance, remarkable anion hybrid storage capability and outstanding structure stability is fully tapped employing UCF as cathode for HSDICs. The electrochemical performance of UCF in a half-cell system at the operating voltage between 1.0 and 4.8 V, achieving an admirable specific discharge capacity of 358.52 mAh·g−1 at 500 mA·g−1, and a high capacity retention ratio of 98.42% after cycling 2500 times at 1000 mA·g−1, respectively. Besides, with the support of ex-situ TEM and EDS mapping, the structural stability principle and anionic hybrid storage mechanism of UCF electrode are investigated in depth. In the full-cell system, HSDICs with the UCF as cathode and hard carbon as anode also presents a super-long cycle stability (80.62% capacity retention ratio after cycling 1300 times at 1000 mA·g−1).

“…Nonetheless, Mn 3+ is prone to the Jahn-Teller effect. High spin Mn 3+ in MnO 6 octahedral units in the materials leads to serious lattice distortion, which usually has a serious adverse influence on structural stability and electrochemical performance [44] .

Sodium-ion batteries (SIBs) are recognized as a leading option for energy storage systems, attributed to their environmental friendliness, natural abundance of sodium, and uncomplicated design. Cathode materials are crucial in defining the structural integrity and functional efficacy of SIBs. Recent studies have extensively focused on manganese (Mn)-based layered oxides, primarily due to their substantial specific capacity, cost-effectiveness, non-toxic nature, and ecological compatibility. Additionally, these materials offer a versatile voltage range and diverse configurational possibilities. However, the complex phase transition during a circular process affects its electrochemical performance. Herein, we set the multiphase Mn-based layered oxides as the research target and take the relationship between the structure and phase transition of these materials as the starting point, aiming to clarify the mechanism between the microstructure and phase transition of multiphase layered oxides. Meanwhile, the structure-activity relationship between structural changes and electrochemical performance of Mn-based layered oxides is revealed. Various modification methods for multiphase Mn-based layered oxides are summarized. As a result, a reasonable structural design is proposed for producing high-performance SIBs based on these oxides.
