Lithium-sulfur batteries (LSBs) are widely acknowledged as the most promising energy storage systems for the future, primarily due to their remarkably high theoretical energy density. Nonetheless, the advancement of LSBs encounters various hurdles, including the substantial expansion of the cathode material, inadequate conductivity of the active material S and discharge product Li2S, the evident shuttle effect of lithium polysulfide (LiPS), and the sluggish sulfur conversion kinetics. These challenges become particularly evident when handling high sulfur loading. The issue of uneven Li dendrit...

A leaf-shaped Sn4P3 on a graphene-carbon nanotube matrix could help to pave the way for fully renewable green energy production.

Hydrogen energy, as a clean and renewable energy, has attracted much attention in recent years. Water electrolysis via the hydrogen evolution reaction at the cathode coupled with the oxygen evolution reaction at the anode is a promising method to produce hydrogen. Given the shortage of freshwater resources on the planet, the direct use of seawater as an electrolyte for hydrogen production has become a hot research topic. Direct use of seawater as the electrolyte for water electrolysis can reduce the cost of hydrogen production due to the great abundance and wide availability. In recent years, ...

Abstract Metal phosphides are regarded as promising anode candidates for high-energy-density potassium-ion batteries (PIBs) due to their high theoretical capacity and relatively low operation voltage. The failure mechanism of the metal phosphides originates from the large volume variation during cycling, which leads to fast capacity degradation. Herein, concentrated electrolyte is used to achieve impressive cycling stability for K-metal and K-ion batteries over their more dilute counterparts, mainly benefiting from the anion-derived robust and uniform solid–electrolyte interphase layer, whi...
