“…To solve the problems of growing exhaustion of fossil energy (petroleum, natural gas, and coal) and the resulting environmental issues, many energy conversion and storage systems, such as lithium-ion batteries (LIBs), nanogenerators, and supercapacitors, have been extensively investigated [1][2][3][4][5][6][7][8][9][10][11][12][13]. LIBs have attracted much attention owing to their low self-discharge, no memory effect, high working voltage, and high energy density [14][15][16][17][18][19]. However, the specific capacity, power density, and rate capability of LIBs should be further improved to meet the demands of high-power energy storage systems [17][18][19].…”

Cobalt oxides have been intensely explored as anodes of lithium-ion batteries to resolve the intrinsic disadvantages of low electrical conductivity and volume change. However, as a precursor of preparing cobalt oxides, Co(OH)2 has rarely been investigated as the anode material of lithium-ion batteries, perhaps because of the complexity of hydroxides. Hybridized Co(OH)2 nanomaterial structures were synthesized by the water bath method and exhibited high electrochemical performance. The initial discharge and charge capacities were 1703.2 and 1262.9 mAh/g at 200 mA/g, respectively. The reversible capacity was 1050 mAh/g after 150 cycles. The reversible capability was 1015 mAh/g at 800 mA/g and increased to 1630 mAh/g when driven back to 100 mA/g. The electrochemical reaction kinetics study shows that the lithium-ion diffusion-controlled contribution is dominant in the energy storage mechanism. The superior electrochemical performance could result from the water bath method and the hybridization of nanosheets and nanoparticles structures. These hybridized Co(OH)2 nanomaterial structures with high electrochemical performance are promising anodes for lithium-ion batteries.

“…On the other hand, engineering of solid electrolyte interphase (SEI) through optimizing electrolytes is also an effective strategy to improve electrochemical performance of anode materials. [ 12–15 ] Resulting from the differences in reduction/oxidation potentials and desolvation energies of different electrolytes, the compositions, and thickness of SEI derived from various electrolytes exhibit discrepancies, which will affect the initial Coulomb efficiency (ICE) and ion diffusion rate of active materials.

Transition metal selenides have been widely used in alkali metal ion batteries owing to their high specific capacities and low cost. However, their reaction kinetics and structural stability are usually poor during cycling, along with ambiguous differences in Li/Na/K-storage behaviors. Herein, it is revealed that ZnSe possesses better Na + -diffusion kinetics (including lower diffusion barrier, smaller activation energy, and higher diffusion coefficients) in comparison with Li + and K + , as evidenced by theoretical calculations and electrochemical studies. The architectural designs of ZnSe-based anode, including nitrogen-doped carbon (N,C) and 3D ordered hierarchical pores (3DOHP) to form a 3DOHP ZnSe@N,C hybrid combined with regulating solid electrolyte interphase (SEI), significantly enhance Na + reaction kinetics and accommodate volume changes. The resulting 3DOHP ZnSe@N,C electrodes exhibit outstanding rate capability and good cycling stability (241.6 mAh g −1 in sodium-ion batteries (SIBs) at 10 A g −1 after 800 cycles), originating from improved electrical conductivity and shortened ion diffusion paths, accompanied by ultrathin and stable SEI with less Na 2 CO 3 /NaF in organic components and boosted Na 2 Se adsorption as sodiation. Moreover, the Na-storage mechanism in 3DOHP ZnSe@N,C hybrid is further revealed by in situ studies. Accordingly, this study provides a new perspective for designing high-performance electrode materials for SIBs.

“…Current commercial graphite anode materials exhibit the advantages of high energy density, high conductivity, and security. Still, their low theoretical capacity of 372mAh/g and poor rate capability have confined the further development of LIBs( Zhang et al, 2019a ; Hou et al, 2020 ; Li et al, 2020b ; Gao et al, 2021 ; Wang et al, 2021a ). Therefore, it is urgent to develop high-performance anode materials to meet the high power energy needs in the future ( Zhao et al, 2019 ; Zhao et al, 2020 ; Liu et al, 2021a ).…”

In order to solve the poor cycle stability and the pulverization of cobalt sulfides electrodes, a series of amorphous and crystalline cobalt sulfides were prepared by one-pot solvothermal synthesis through controlling the reaction temperatures. Compared to the crystalline cobalt sulfide electrodes, the amorphous cobalt sulfide electrodes exhibited superior electrochemical performance. The high initial discharge and charge capacities of 2,132 mAh/g and 1,443 mAh/g at 200 mA/g were obtained. The reversible capacity was 1,245 mAh/g after 200 cycles, which is much higher than the theoretical capacity. The specific capability was 815 mAh/g at 800 mA/g and increased to 1,047 mAh/g when back to 100 mA/g, indicating the excellent rate capability. The outstanding electrochemical performance of the amorphous cobalt sulfide electrodes could result from the unique characteristics of more defects, isotropic nature, and the absence of grain boundaries for amorphous nanostructures, indicating the potential application of amorphous cobalt sulfide as anodes for lithium-ion batteries.
