Fe single atoms and N co‐doped carbon nanomaterials (Fe‐N‐C) are the most promising oxygen reduction reaction (ORR) catalysts to replace platinum group metals. However, high‐activity Fe single‐atom catalysts suffer from poor stability owing to the low graphitization degree. Here, an effective phase‐transition strategy is reported to enhance the stability of Fe‐N‐C catalysts by inducing increased degree...
The local coordination environment of catalytical moieties directly determines the performance of electrochemical energy storage and conversion devices, such as Li–O2 batteries (LOBs) cathode. However, understanding how the coordinative structure affects the performance, especially for non‐metal system, is still insufficient. Herein, a strategy that introduces S‐anion to tailor the electronic structure...
Emerging directions in the growing wearable electronics market have spurred the development of flexible energy storage systems that require deformability while maintaining electrochemical performance. However, the traditional fabrication approaches of lithium‐ion batteries (LIBs) are challenging to withstand long‐cycle bending alternating loads due to the stress concentration caused by the nonuniformity...
Mitigating the mechanical degradation and enhancing the ionic/electronic conductivity are critical but challengeable issues toward improving electrochemical performance of conversion‐type anodes in rechargeable batteries. Herein, these challenges are addressed by constructing interconnected 3D hierarchically porous structure synergistic with Nb single atom modulation within a Co3O4 nanocage (3DH‐Co...
Titanium‐based oxides including TiO2 and M‐Ti‐O compounds (M = Li, Nb, Na, etc.) family, exhibit advantageous structural dynamics (2D ion diffusion path, open and stable structure for ion accommodations) for practical applications in energy storage systems, such as lithium‐ion batteries, sodium‐ion batteries, and hybrid pseudocapacitors. Further, Ti‐based oxides show high operating voltage relative...
The oxygen reduction reaction (ORR) plays an important role in the fields of energy storage and conversion technologies, including metal–air batteries and fuel cells. The development of nonprecious metal electrocatalysts with both high ORR activity and durability to replace the currently used costly Pt‐based catalyst is critical and still a major challenge. Herein, a facile and scalable method is...
