Special Issue Information

Dear Colleagues,

In recent years, energy and environmental issues have received increasing attention. For the sustainable development of humanity, many countries have successively formulated plans for carbon emission reduction. The development of new energy technologies provides possible solutions for the realization of these goals. For example, fuel cells can directly convert the chemical energy in hydrocarbon fuel or hydrogen into electrical energy with high efficiency. Solar cells can convert sunlight energy into electrical energy with no carbon emissions. Advanced secondary batteries such as lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, and all-solid-state batteries can achieve the efficient storage of electrical energy and expand the application of electricity in various fields of society. People's exploration, learning, and utilization of the surface/interface science of energy materials are key factors that promote the development of the above-mentioned energy technologies. Therefore, we are setting up this Special Issue to share the new discoveries and developments of surface/interface science of advanced energy materials. Original research articles, communications, perspectives, and comprehensive review papers related to this topic are welcome.

In particular, the topics of interest include, but are not limited to, the following:

(1) Solid oxide fuel cells;

(2) Solid oxide electrolyzers/electrolysis cells;

(3) Solar cells;

(4) Lithium-ion batteries;

(5) Sodium-ion batteries;

(6) Lithium-sulfur batteries;

(7) All-solid-state batteries;

(8) Metal air batteries (Li-air, Mg-air, Al-air and Zn-air batteries);

(9) Cathode/anode electrode material;

(10) Electrolyte material;

(11) Thin film;

(12) Coating layers.

The development of a novel electrode material for energy storage devices is a grand challenge. Here, through a rational design of the structure, the electrochemical performance of the prepared sample could be improved while enhancing the conductivity and the synergistic effect of its components. Herein, we constructed a core–shell composite named Ni–Co–O/NiCo-LDH as the electrode material by a self-template method, which comprised hydrothermal and annealing steps. The as-prepared material exhibited a Chinese chestnut-like structure, and the core–shell structure was based on nanoneedles. The pseudocapacitance characteristics of the Ni–Co–O/NiCo-LDH electrode were significantly improved due to the good electrical conductivity of the core material and the unique core–shell structure, which led to a high electrochemical performance, reaching a high specific capacitance of 1434 F g−1 at the current density of 1 A g−1. When assembled in a device with activated carbon (AC) as the negative electrode, the supercapacitor showed an energy density of 26 Wh kg−1 at a power density of 807 W kg−1. Simultaneously, the device showed an excellent cycle stability, with 95% capacity retention after 3600 cycles at a current density of 6 A g−1, which could largely widen the application of the supercapacitor.

In order to reduce the mechanical sensitivity of ε-CL-20, wax and fluororubber polymers were used as coating materials and desensitizers to coat ε-CL-20 by the water suspension method. Through molecular dynamics calculations, fluorine rubber F2311, which had a good combination with ε-CL-20, was selected as the coating material and then ε-CL-20-based composite particles with double-layer structure were prepared. The contact angles of water, glycerin and diiodomethane as the testing liquids on the surface of F2311 and wax were measured by a contact angle measuring instrument, and the thermodynamic parameters of ε-CL-20/F2311 and the ε-CL-20/wax interface were calculated. ε-CL-20 before and after coating was characterized by scanning electron microscopy (SEM), X-ray diffractometry (XRD), differential scanning calorimetry (DSC), and the mechanical sensitivity analytical method. The results showed that F2311/wax had uniformly passivated on the surface of ε-CL-20, forming a dense and uniform protective film, and the CL-20 crystal form did not change after coating. The double-layer composite structure effectively reduces the sensitivity of ε-CL-20 and improves the thermal stability of ε-CL-20. Full article
