Special Issue Information

Dear Colleagues,

An ever-increasing societal demand for energy calls for sustainable solutions to producing and storing energy. Recent theoretical and experimental developments in multifunctional coatings as single or multilayers covering nanomaterials are among the most highly exploited research areas in of energy storage and conversion science, either improving the efficiency or durability of the devices. Driven by the current knowledge of energy storage and conversion mechanisms, the need to maintain device performance and reliability assets under harsh environments, and a renewed impetus towards the durability of new nanostructured coating systems, have seen a huge demand for experimental, theoretical and modeling activities.

This collection covers the design of coating materials on devices about solar-cell, fuel-cell, battery and capacitor technologies, in addition to those focusing on the catalytic production of fuels using solar and electrical energy. The scope of this Special Issue will serve as a forum for papers on the following concepts:

  1. Theoretical and experimental research, knowledge and new ideas in energy storage and conversion of protective and preventive coatings materials.
  2. Recent developments in multi-functional organic, inorganic and hybrid coatings.
  3. Coatings produced by different processes, including but not limited to additive manufacturing processes, thermal spray, sputtering, laser and plasma processing, CVD, ALD, plating, etc.
  4. Experimental and processing high-performance coatings with exposure to high temperatures, high stress and other extreme environment applications.
  5. Understanding the degradation mechanisms of coatings on the device's performance and durability.
  6. The latest development of test methods considering the interplay between mechanical, chemical and electrochemical interactions and the ability to predict performance and/or reliability.
  7. Computer modeling and simulation to predict coating properties, performance, durability and reliability in energy storage and conversion systems.

Lithium/carbon fluoride (Li/CFx) batteries have been widely researched due to their high theoretical specific energy. To create a high-performance electrode, the fluorinated hard carbon (FHC) is prepared by direct gas-phase fluorination. It has a high F/C ratio of 0.95 based on the gravimetric method. Selecting hard carbon (HC) with a high surface area as the carbon source allows for FHC to achieve suitable interlayer spacing and specific surface area, as well as abundant pore structures to facilitate rapid lithium ion transportation. Additionally, a composite of graphene and carbon nanotubes (CNTs) is coated on the surface of FHC, enhancing electron transport speed. The resulting FHC&C exhibits a very high energy density of 1256 Wh kg−1 and an excellent power density of 72,929 W kg−1 at a high rate of 40 C. Moreover, compared to commercial CFx, FHC&C exhibits higher energy and power densities, thus presenting a promising practical application prospect. Full article

Germanium-tin (GeSn) alloy is considered a promising candidate for a Si-based short-wavelength infrared range (SWIR) detector and laser source due to its excellent carrier mobility and bandgap tunability. Pulsed laser annealing (PLA) is one of the preeminent methods for preparing GeSn crystal films with high Sn content. However, current reports have not systematically investigated the effect of different pulse-width lasers on the crystalline quality of GeSn films. In addition, the intensity of the spot follows the gaussian distribution. As a result, various regions would have different crystalline properties. Therefore, in this study, we first provide the Raman spectra of several feature regions in the ablation state for single spot processing with various pulse-width lasers (continuous-wave, nanosecond, femtosecond). Furthermore, the impact of laser pulse width on the crystallization characteristics of GeSn film is explored for different single-spot processing states, particularly the Sn content incorporated into GeSn crystals. The transient heating time of the film surface and the faster non-equilibrium transition of the surface temperature inhibit the segregation of the Sn component. By comparing the Raman spectra of the pulsed laser, the continuous-wave laser shows the most acute Sn segregation phenomenon, with the lowest Sn content of approximately 2%. However, the femtosecond laser both ensures crystallization of the film and effective suppression of Sn expulsion from the lattices, and the content of Sn is 8.07%, which is similar to the origin of GeSn film.
