Van der Waals heterostructure engineering by 2D space-confinement for advanced potassium-ion storage

Bi Luo et al.

Summary: A two-dimensional space confined strategy is proposed to construct van der Waals heterostructures for superior potassium-ion battery (PIB) anodes. The synergistic effects in the 2D heterostructure greatly enhance electron transportation and ions diffusion, while inhibiting polysulfide dissolution for increased structural durability. As a result, the synthesized C/MoS2/G anode demonstrates remarkable K-storage performance with high reversible capacity, excellent rate capability, and superior long-cycling stability.

Effect of Fluoroethylene Carbonate on Solid Electrolyte Interphase Formation of the SiO/C Anode Observed by In Situ Atomic Force Microscopy

Rui Zhao et al.

Summary: Silicon oxide-based materials show promise as anode materials for lithium-ion batteries, with the solid electrolyte interphase playing a crucial role in the performance. A study on the effect of fluoroethylene carbonate (FEC) on the interface film formation of commercial SiO/C anode revealed a dense and stiff SEI layer in FEC-based electrolyte, in contrast to the scattered and thin SEI layer in ethylene carbonate-based electrolyte.

Enhancing potassium-ion battery performance by MoS2 coated nitrogen-doped hollow carbon matrix

Qingqing Jiang et al.

Summary: Coating MoS2 nanosheets on porous carbon polyhedrons derived from zeolite imidazole framework-8 as anode materials for potassium-ion batteries results in excellent electrochemical performance due to unique hybrid structures and synergistic effects between MoS2 and N-doped carbon polyhedron, enhancing electronic conductivity, shortening potassium-ion diffusion distance, relieving MoS2 nanosheet agglomeration, mitigating volume variation, and providing numerous active sites for potassium ion accommodation.

Fe0.8CoSe2 nanosphere coated by N-doped carbon for ultra-high rate potassium selenium battery

Xin-Xin Jia et al.

Summary: In this study, a hollow nano-spherical Co-Fe bi-metallic selenide coated with N-doped carbon (CFS@N-C) was designed as a cathode for potassium-selenium batteries, showing excellent rate performance and slow-charge/ultrafast-discharge capability with nearly 100% Coulombic efficiency. The charge-discharge mechanism was revealed to be K+ replacing the bimetal and forming K2Se, providing directions for researching high power density potassium storage materials.
