Lithium-rich layered oxides (LLOs) are considered as the most promising candidate for the cathode of high energy density lithium-ion batteries. However, the poor cycle stability especially under high temperature is hindering its practical applications. Herein, a full concentration gradient LLO with spinel modification is designed and prepared. This...
Nitrogen and sulfur co-doped hierarchical porous carbon (N, S-HPC) is synthesized by using polyaniline and poly (3,4-ethylenedioxythiophene) as doping sources and polytetrafluoroethylene as the silica template removal agent for lithium-sulfur batteries. N,S-HPC shows the interconnected hierarchical porous network, which enables sulfur to be uniform...

The increased concentration of CO2 due to continuous breathing and no discharge of human beings in the manned closed space, like spacecraft and submarines, can be a threat to health and safety. Effective removal of low concentration CO2 from the manned closed space is essential to meet the requirements of long-term space or deep-sea exploration, wh...

With the increasing demand for energy, layered lithium-rich manganese-based (Li-rich Mn-based) materials have attracted extensive attention because of their high capacity and high voltage. However, the Li-rich Mn-based materials suffer from a series of problems of oxygen release, transition metal (TM) migration, and structural transformation, which...
Minimizing the particle size and constructing specific structures to accommodate the volumetric change of anodes for secondary batteries are significant. Herein, we develop a spiral [email protected] nanowire, which reduces the agglomeration of nanoparticles (approximate to 10 nm) and accommodates the volumetric change of Fe2O3 during charge and discharge...
Aqueous hybrid Na–Zn ion batteries (ASZIBs) are promising for large‐scale energy storage due to their low cost and potential for high output voltage. However, most ASZIBs show limited discharge voltage (
In this communication, nano-thin carbon-encapsulated Sb6O13 nanoparticles (Sb(6)O(13)[email protected]) synthesized innovatively in a one-pot manner were demonstrated as a high-performance anode material for Na-ion batteries. The synthesized Sb(6)O(13)[email protected] bearing irregular nanopores showed an average size of around 60 nm and possessed the 13.6 wt% carbon she...
