Seeking organic cathode materials with low cost and long cycle life that can be employed for large‐scale energy storage remains a significant challenge. This work has synthesized an organic compound, triphenazino[2,3‐b](1,4,5,8,9,12‐hexaazatriphenylene) (TPHATP), with as high as 87.16% yield. This compound has a highly π‐conjugated and rigid molecular structure, which is synthesized by capping hexaketocyclohexane...
The interfacial electron modulation of electrocatalysts is an effective way to realize efficient hydrogen production, which is of great importance for future renewable energy systems. However, systematic theory‐guided design of catalysts in heterojunction coupling is lacking.

Solution‐processed organic–inorganic hybrid perovskite polycrystalline thick films have shown great potential in X‐ray detection. However, the preparation of compact perovskite thick films with large area is still challenging due to the limitation of feasible ink formulation and pinholes caused by solvent volatilization. Post‐treatment and hot‐pressing are usually involved to improve the film quality,...
Aqueous rechargeable zinc‐based batteries (ZBBs) are emerging as desirable energy storage systems because of their high capacity, low cost, and inherent safety. However, the further application of ZBBs still faces many challenges, such as the issues of uncontrolled dendrite growth and severe parasitic reactions occurring at the Zn anode.

Lithium‐rich layered oxide (LRLO) materials have attracted significant attention due to their high specific capacity, low cost, and environmental friendliness. However, owing to its unique capacity activation mechanism, the release of lattice oxygen during the first charge process leads to a series of problems, such as severe voltage decay, poor cycle stability, and poor rate performance. Herein,...
Sodium (Na) metal is able to directly use as a battery anode but have a highly reductive ability of unavoidably occurring side reactions with organic electrolytes, resulting in interfacial instability as a primary factor in performance decay. Therefore, building stable Na metal anode is of utmost significance for both identifying the electrochemical performance of laboratory half‐cells employed for...
In consideration of high specific capacity and low redox potential, lithium metal anodes have attracted extensive attention. However, the cycling performance of lithium metal batteries generally deteriorates significantly under the stringent conditions of high temperature due to inferior heat tolerance of the solid electrolyte interphase (SEI).
