“…However, the standard, selection of the sol–gel complexing agent has not been unified. Liu et al [92a] explored Na 0.9 Ni 0.45 Mn 0.55 O 2 synthesized by different complexing agents and found that the choice of complexing agents had a great influence on the structure, morphology, and even the electrochemical properties of the cathode material. Liu's group [92c] synthesized NVPF cathode materials at low temperatures by an anhydrous solvent method.…”

Sodium‐ion batteries are promising candidates for grid‐scale energy storage due to its abundance and similarities to lithium‐ion batteries, whereas the lack of ideal cathode materials limits their practical development. Apart from exploring novel materials, applying optimization strategies on existing potential cathode materials is demonstrated to be effective and efficient in improving their electrochemical properties toward their theoretical best capabilities. Reported strategies include element doping, surface coating, morphology and structure design, defect engineering, etc. Herein, focusing on oxide and polyanionic cathode materials, a comprehensive and systematic review on emerging optimization strategies is provided by discussing representative studies of each. Corresponding fundamental principles, their applicable ranges, and common influences on properties are analyzed. Finally, the perspectives on the current impediments and future directions in the field are presented.

“…Owing to energy shortages, air pollution and population growth, intermittent energy sources (e.g., solar energy and wind power) have been utilized to substitute traditional ones, which greatly promotes the development of energy storage devices (Lv et al, 2018 , 2019 ; Liu et al, 2020 ). Among these devices, due to high efficiency, zero-emission, and low noise, lithium batteries have attracted considerable attention and have already been used in various applications (Nishi, 2001 ; Goodenough and Kim, 2010 ).…”

Lithium batteries are widely used in portable electronic products. Although the performance of the batteries has been greatly improved in the past few decades, limited understanding of the working mechanisms at an atomic scale has become a major factor for further improvement. In the past 10 years, a reaction force field (ReaxFF) has been developed within the molecular dynamics framework. The ReaxFF has been demonstrated to correctly describe both physical processes and chemical reactions for a system significantly larger than the one simulated by quantum chemistry, and therefore in turn has been broadly applied in lithium batteries. In this article, we review the ReaxFF studies on the sulfur cathode, various anodes, and electrolytes of lithium batteries and put particular focus on the ability of the ReaxFF to reveal atomic-scale working mechanisms. A brief prospect is also given.

“…At the same time, the application of electric vehicles requires devices with low cost, high safety, high power, and high energy density. Compared with batteries, [1][2][3][4][5][6] supercapacitors are an important part of current research in the energy field due to their high power density, excellent performance, robust life, and extensive range of work temperature. [7][8][9][10][11][12] Generally, transition metal oxides/hydroxides (such as MnO 2 , NiO, Co 3 O 4 , NiCo 2 O 4 , and CoMoO 4 ) and conductive polymers (including polyaniline and polypyrrole) are used in pseudocapacitors.…”

The urchin-like NiCo 2 O 4 material was prepared by a one-step hydrothermal method. The optimal synthetic conditions were systematically investigated by an orthogonal test method and single factor of hydrothermal time to evaluate the influence of sample morphology and electrochemical performance. The synthesis conditions for preparing NiCo 2 O 4 with different morphologies were systematically studied. In the single factor experiment, when the hydrothermal time is 6, 12, 16, and 24 hours, the corresponding morphologies are urchin-like (NCO-U), flower-like (NCO-F), sheet-like (NCO-S), and block-like (NCO-B), respectively. The element content of the prepared materials under different synthesis conditions was tested by an inductive-coupled plasma emission spectrometer, and an interesting phenomenon was found. As the reaction time
