“…Raman scattering mapping and X-ray photo-electron spectroscopy of n-and p-type silicon after lithiation conclusively showed that highly doped n-type Si (100) surface regions retain Li as a silicide and convert to an amorphous phase during early cycles via a polycrystalline phase as a two-step phase conversion process [197].…”

This review outlines the developments and recent progress in metal-assisted chemical etching of silicon, summarizing a variety of fundamental and innovative processes and etching methods that form a wide range of nanoscale silicon structures. The use of silicon as an anode for Li-ion batteries is also reviewed, where factors such as film thickness, doping, alloying, and their response to reversible lithiation processes are summarized and discussed with respect to battery cell performance. Recent advances in improving the performance of silicon-based anodes in Li-ion batteries are also discussed. The use of a variety of nanostructured silicon structures formed by many different methods as Li-ion battery anodes is outlined, focusing in particular on the influence of mass loading, core-shell structure, conductive additives, and other parameters. The influence of porosity, dopant type, and doping level on the electrochemical response and cell performance of the silicon anodes are detailed based on recent findings. Perspectives on the future of silicon and related materials, and their compositional and structural modifications for energy storage via several electrochemical mechanisms, are also provided.

“…The possible electrochemical responses of many metal oxide thin films imply that they are not limited to use in sensors and electronic or optics but can also be of great benefit for battery technologies . An ideal thin film battery would have a compact size while retaining a high electrode surface area and be capable of a rapid charge/discharge cycle without capacity fade . These attributes can be obtained through the use and incorporation of flexible electrodes and substrates with thin film technologies.…”

A comprehensive review of recent advances in solution processing and growth of metal‐oxide thin films for electronic and photonic devices is presented, with specific focus on precise solution‐based technological coatings for electronics and optics, and new concepts for oxide material growth for electrochemical, catalytic, energy storage and conversion systems, information technology, semiconductor device processing and related devices. Throughout, the nature of the soluble precursors solutions and their relationship to film formation process by various solution coating techniques are collated and compared, highlighting advantages in precursor design for creating complex oxides for devices. Because of the versatility of solution‐processable oxides and functional material coating, it is important to capture the advances made in oxide deposition for plastic electronics, see‐through and wearable devices, and high‐fidelity thin film transistors on curved or flexible displays. Solution processing, even for oxides, allows control over composition, thickness, optical constants, porosity, doping, tunable optical absorbance/transmission, band structure engineering, 3D‐substrate coating, complex composite oxide formation and multi‐layered oxide systems that are more difficult to achieve using chemical vapor deposition (CVD) or atomic layer deposition (ALD) processes. We also discuss limitations of solution processing for some technologies and comment on the future of solution‐based processing of metal‐oxide materials for electronics, photonics and other technologies.

“…At the core of the importance of crystallinity and composition, is its relation to the solid state electrochemistry with respect to lithium interactions – the reader is referred to an excellent review by Goodenough [4] on the solid state chemistry of these concepts [4] . There is a large body of evidence confirming the importance of surface orientation,[130] interfaces with solutions, and crystallographic orientation for materials in catalysis,[48,131–133] semiconductor micro-nanoelectronics (etching), charge storage, electrochemistry, sensors, etc., and the crystallographic orientations of crystalline materials have also become crucial for defining the important parameters of battery materials.

This perspective reviews recent advances in inverse opal structures, how they have been developed, studied and applied as catalysts, catalyst support materials, as electrode materials for batteries, water splitting applications, solar-to-fuel conversion and electrochromics, and finally as photonic photocatalysts and photoelectrocatalysts. Throughout, we detail some of the salient optical characteristics that underpin recent results and form the basis for light-matter interactions that span electrochemical energy conversion systems as well as photocatalytic systems. Strategies for using 2D as well as 3D structures, ordered macroporous materials such as inverse opals are summarized and recent work on plasmonic–photonic coupling in metal nanoparticle-infiltrated wide band gap inverse opals for enhanced photoelectrochemistry are provided.
