“…This inconspicuous reduction peak could result from the insertion of lithium ions into the Co(OH)2 electrodes. The CV curves almost overlap after the third cycle, indicating the excellent stability of the electrochemical reaction during cycles [50,51]. The first five discharge-charge curves at 100 mA/g are shown in Figure 5b to compare with the CV curves shown in Figure 5a.…”

“…The two Nyquist plots (scatters), which are composed of two semicircles in high frequency and a straight line in low frequency, can be well fitted by the equivalent circuit (fitting line) shown in the inset of Figure 6a. The parameters of Rs, Rcf, Rct, and Zw denote the ohmic resistance of the electrode and electrolyte, the impedance of the SEI layer, the charge transfer resistance, and the Warburg impedance [17][18][19]50,52]. The Li-ions diffusion coefficient (DLi + ) is an essential parameter of electrodes, and it can be obtained by the following equations: The physical parameters above include the gas constant (R), the measuring temperature (T), the surface area of the electrode (A), the number of transferred electrons (n), the Faraday constant (F), the concentration of lithium ions (C), the Warburg coefficient (σ), and the angle frequency (ω), respectively [50,52].…”

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.

In recent years, metal‐organic frameworks, especially MOF‐based derivatives, have been regarded as one of the best candidate electrode materials for the next generation of advanced materials, due to high porosity, large surface area, modifiable functional groups as well as controllable chemical composition. This review presents the corresponding synthesis methods, structural design, and electrochemical performance of MOF‐derived materials, including metal oxides, metal sulfides, metal phosphides, and carbon materials, in high‐performance lithium‐ion batteries. Subsequently, the problems that exist in the current application of MOF‐based derivatives as electrodes in lithium‐ion batteries are discussed along with possible and feasible solutions. At last, some reasonable pathways and strategies for the design of MOF derivatives are also suggested.
