The discovery of the heterostructures that is combining two materials with different properties has brought new opportunities for the development of lithium sulfur batteries (LSBs). Here, C3N4‐CoSe2 composite is elaborately designed and used as a functional coating on the LSBs separator. The abundant chemisorption sites of C3N4‐CoSe2 form chemical bonding with polysulfides, provides suitable adsorption...
Halloysite nanotubes (HNTs) have emerged as a highly regarded choice in biomedical research due to their exceptional attributes, including superior loading capacity, customizable surface characteristics, and excellent biocompatibility. HNTs feature tubular structures comprising alumina and silica layers, endowing them with a large surface area and versatile surface chemistries that facilitate selective...
Li‐rich Mn‐based cathodes have been regarded as promising cathodes for lithium‐ion batteries because of their low cost of raw materials (compared with Ni‐rich layer structure and LiCoO2 cathodes) and high energy density. However, for practical application, it needs to solve the great drawbacks of Li‐rich Mn‐based cathodes like capacity degradation and operating voltage decline. Herein, an effective...
Orthorhombic MoO3 (α‐MoO3) with multivalent redox couple of Mo6+/Mo4+ and layered structure is a promising cathode for rechargeable aqueous Zn‐ion batteries (AZIBs). However, pure α‐MoO3 suffers rapid capacity decay due to the serious dissolution and structural collapse. Meanwhile, the growth of byproduct and dendrite on the anode also lead to the deterioration of cyclic stability. This article establishes...
Li–CO2 battery provides a new strategy to simultaneously solve the problems of energy storage and greenhouse effect. However, the severe polarization of CO2 reduction and CO2 evolution reaction impede the practical application. Herein, anodic TiO2 nanotube arrays are first introduced as carbon‐free and free‐standing cathode for photo‐assisted Li–CO2 battery, and the photo‐assisted charge and discharge...
Optimizing the coordination structure and microscopic reaction environment of isolated metal sites is promising for boosting catalytic activity for electrocatalytic CO2 reduction reaction (CO2RR) but is still challenging to achieve. Herein, a newly electrostatic induced self‐assembly strategy for encapsulating isolated Ni‐C3N1 moiety into hollow nano‐reactor as I‐Ni SA/NHCRs is developed, which achieves FE...
