Li‐O2 batteries could deliver ultra‐high theoretical energy density compared to current Li‐ion batteries counterpart. The slow cathode reaction kinetics in Li‐O2 batteries, however, limits their electrocatalytic performance. To this end, MoSe2 and Ni0.85Se nanoflakes were decorated in carbon hollow nanoflowers, which were served as the cathode catalysts for Li‐O2 batteries. The hexagonal Ni0.85Se...
The development of cerium (Ce) single‐atom (SA) electrocatalysts for oxygen reduction reaction (ORR) with high active‐site utilization and intrinsic activity has become popular recently but remains challenging. Inspired by an interesting phenomenon that pore‐coupling with single‐metal cerium sites can accelerate the electron transfer predicted by density functional theory calculations, here, a facile...
Sodium (Na)‐ion batteries (SIBs) have been considered as a potential device for large‐scale energy storage. To date, some start‐up companies have released their first‐generation SIBs cathode materials. Among them, phosphate compounds, particularly iron (Fe)‐based mixed phosphate compounds, present great potential for commercial SIBs owing to its low cost, environment friendly. In this perspective,...
Li‐O2 batteries are acknowledged as one of the most promising energy systems due to their high energy density approaching that of gasoline, but the poor battery efficiency and unstable cycling performance still hinder their practical application. In this work, hierarchical NiS2‐MoS2 heterostructured nanorods are designed and successfully synthesized, and it is found that heterostructure interfaces...
Sodium‐ion batteries (SIBs) have attracted wide interest for energy storage because of the sufficient sodium element reserve on the earth; however, the electrochemical performance of SIBs cannot achieve the requirements so far, especially, the limitation of cathode materials. Here, a kilogram‐scale route to synthesize Na2FePO4F/carbon/multi‐walled carbon nanotubes microspheres (NFPF@C@MCNTs) composite...
Mesenchymal stem cell (MSC) therapy can attenuate organ damage and reduce mortality in sepsis; however, the detailed mechanism is not fully elucidated. In this study, it is shown that MSC‐derived apoptotic vesicles (apoVs) can ameliorate multiple organ dysfunction and improve survival in septic mice. Mechanistically, it is found that tail vein‐infused apoVs mainly accumulate in the bone marrow of...
Developing an excellent bifunctional catalyst is essential for the commercial application of Li‐O2 batteries. Heterostructures exhibit great application potential in the field of energy catalysis because of the accelerated charge transfer and increased active sites on their surfaces. In this work, CoS2 nanoparticles decorated on MoS2 nanorods are constructed and act as a superior cathode catalyst...
