Special Issue Information

Dear Colleagues,

Integrating intermittent renewable resources such as solar and wind power with energy storage systems (EES) is unarguably beneficial for electricity grid. Although lithium-ion battery with high energy density has achieved a great success in portable electronics and electric vehicles, its large-scale application in ESS is hampered by its high cost, scarce resources (lithium, cobalt, etc.) and intrinsic safety concerns. In this regard, next-generation battery systems with cost competitiveness, good reliability and high safety are highly desired to meet the various needs of future power grid and e-mobility applications. Electrode coating, as a popular strategy to improve batter performance, has been proven efficient in upgrading both anodes (e.g., suppressing dendrite growth) and cathodes (e.g., preventing electrolyte corrosion) of batteries. In recent years, multifunctional coatings have been playing indispensable role in designing promising next-generation EES such as lithium/sodium/zinc-ion batteries and solid-state batteries.

This special issue will cover surface and interface modifications of electrode materials for different battery chemistries, especially “beyond lithium-ion”, aimed at next-generation energy storage. Considering your outstanding contribution in this emerging field, I would like to cordially invite you to submit a research paper or a mini review of your research to this special issue focusing on the application of electrode coating in the context of following topics:

  • Lithium-ion and lithium-metal batteries
  • Sodium-ion and sodium-metal batteries
  • Aqueous zinc-ion and zinc-metal batteries
  • Supercapacitors
  • Aqueous metal-air batteries
  • Other alkali and multivalent batteries including K, Al, and Mg batteries
  • Solid-state lithium/sodium-metal batteries

The scope includes their material development, testing, modelling, applications, and economy analysis.

The development of cobalt-free P2-Na2/3Ni1/3Mn2/3O2 cathodes is hampered by poor electrochemical performance, resulting from structural instability during high-voltage cycling. Herein, Li+ and F ions are introduced simultaneously via a simple sol–gel method. The F not only enters the lattice but forms chemically stable NaF on the surface. The modified electrode delivered significantly better electrochemical performance than the pristine one, including much-enhanced capacity retention (64% vs. 36%, 100 cycles) at 0.5 C and a four-time higher capacity output at 10 C. The ex situ XRD and in situ Raman analysis revealed cyclability enhancement mechanisms in terms of inhibiting the P2–O2 phase transition and Na+/vacancy ordering. The conductivity measurements (based on AC impedance and DC polarization) and GITT analysis proved, on both bulk material and electrode levels, that Na+ conduction and, thus, rate performance is notably promoted by doping. The individual contribution of Li and F to the overall performance improvement was also discussed. Furthermore, a solid-state sodium-metal battery was successfully demonstrated with the modified cathode. The above results verify that Li+/F incorporation can enable enhancements in both cyclability and rate capability of the P2-Na2/3Ni1/3Mn2/3O2 cathodes and are expected to provide a new perspective for the rational design of high-performance layered oxide cathode materials for progressive sodium-ion batteries.

High-performance electrode materials are crucial to the improvement of the supercapacitor performance index. Ni2Co1HCF@CoNi-LDH composites with a core–shell structure were prepared by a combination of coprecipitation and constant potential electrodeposition, and the microscopic morphology and phase composition of the composites were characterized by XRD, SEM, FTIR and XPS. The results showed that the NiCo Prussian blue (Ni2Co1HCF) was grown on the nickel foam (NF) substrate by in situ etching, while the nickel–cobalt double hydroxide (CoNi-LDH) was covered on the NiCo Prussian blue surface by electrodeposition, and the composite still retained the cubic skeleton morphology of the NiCo Prussian blue. The electrochemical properties of the composites were investigated using a three-electrode system in 2 M KOH. The results showed that their discharge specific capacity was as high as 1937 F·g−1 at a current density of 1 A·g−1 and still had 81.3% capacity retention at 10 A·g−1, and they exhibited an excellent rate capability. The capacity retention rate was 87.1% after 1000 cycles at 5 A·g−1 and, thus, the composite material has good application prospects as a supercapacitor electrode material. Full article
