“…The ESD technique can be applied to design suitable components and structures of catalysts. For example, a porous Co 3 O 4 /Ketjenblack cathode film was directly deposited on Ni foam by the ESD technique as the cathode of a Li–O 2 battery . The optimized Co 3 O 4 /Ketjenblack (80%) composite film exhibited the best performance.…”

The development of advanced electrode materials for various energy-storage systems, especially the fabrication of designed structures and morphologies of electrode materials, has attracted intense interest in both the academic and industrial fields. Among the various synthesis methods, electrostatic spray deposition (ESD) is a simple but versatile approach, by which materials can be fabricated with various morphologies, such as granular, dense, and porous, in an easily controllable manner. Herein, motivated by the rapid advancements of the given technology, a comprehensive introduction of ESD is provided, with emphasis on the kinds of materials and the types of morphology that can be obtained, along with the important control parameters. The progress on electrode materials, which are applied in a great variety of energy-storage systems, such as Li-ion batteries, Na-ion batteries, supercapacitors, Li-S batteries, and Li-O 2 batteries, prepared by ESD is also summarized. How the specific morphologies designed by ESD improve the electrochemical performance for different types of electrode materials is also discussed. The aim is to promote the collaborative efforts among different communities to optimize and develop the ESD technique and to explore advanced electrode materials for energy storage.

Advanced electrode materials have been intensively explored for next-generation lithium-ion batteries (LIBs), and great progresses have been achieved for many potential candidates at the labscale. To realize the commercialization of these materials, industrially-viable synthetic approaches are urgently needed. Spray pyrolysis (SP), which is highly scalable and compatible with on-line continuous production processes, offers great fidelity in synthesis of electrode materials with complex architectures and chemistries. In this review, motivated by the rapid advancement of the given technology in the battery area, we have summarized the recent progress on SP for preparing a great variety of anode and cathode materials of LIBs with emphasis on their unique structures generated by SP and how the structures enhanced the electrochemical performance of various electrode materials. Considering the emerging popularity of sodium-ion batteries (SIBs), recent electrode materials for SIBs produced by SP will also be discussed. Finally, the powerfulness and limitation along with future research efforts of SP on preparing electrode materials are concisely This article is protected by copyright.

“…Among these samples with different CoO x loadings (from 12.8 to 75.3 wt%), the 38.9 wt% CoO x /CG composite cathode showed the lowest average polarization of 1.17 V, but no more specific explanation was given. In contrast, a Co 3 O 4 /Ketjen black (KB) composite with different KB concentrations (from 20 to 80 wt%) was fabricated by Zhang et al 70 Benefiting from the compromise between electric conductivity and electrocatalytic activity, the Co 3 O 4 /KB (80 wt%) electrode exhibits the lowest overpotential less than 1.0 V and the most stable cycling performance. In addition, Wang et al 71 In addition to the material composition, the electrode microstructure was found to have a significant effect on the performance of oxygen electrodes in Li-O 2 batteries.…”

Aprotic lithium-oxygen (Li-O 2 ) batteries represent a promising next-generation energy storage system due to their extremely high theoretical specific capacity compared with all known batteries. Their practical realization is impeded, however, by the sluggish kinetics for the most part, resulting in high overpotential and poor cycling performance. Due to the high catalytic activity and favorable stability of Co-based transition metal oxides, they are regarded as the most likely candidate catalysts, facilitating researchers to solve the sluggish kinetics issue. Herein, this review first presents recent advanced design strategies for Co-based transition metal oxides in Li-O 2 batteries. Then, the fundamental insights related to the catalytic processes of Co-based transition metal oxides in traditional and novel Li-O 2 electrochemistry systems are summarized.Finally, we conclude with the current limitations and future development directions of Co-based transition metal oxides, which will contribute to the rational design of catalysts and the practical applications of Li-O 2 batteries.
