“…Electrochemical water splitting to produce hydrogen fuel has been recognized as a highly promising technology for storing zero-carbon electricity generated from intermittent and nondispatchable renewable energy sources. [1][2][3][4][5] Generally, the water DOI: 10.1002/aenm.202301391 splitting technology comprises two half reactions: the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). Unlike the HER which involves a relatively straightforward twoelectron transfer step, the OER is a more complex process that requires fourelectron transfer steps.…”

Transition metal‐based oxyhydroxides (MOOH) derived from the irreversible structural reconstruction of precatalysts are often acknowledged as the real catalytic species for the oxygen evolution reaction (OER). Typically, the reconstruction‐derived MOOH would exhibit superior OER activity compared to their directly synthesized counterparts, despite being fundamentally similar in chemistry. As such, structural reconstruction has emerged as a promising strategy to boost the catalytic activity of electrocatalysts. However, the in‐depth understanding of the origin of the superior OER activity of reconstructed materials still remains ambiguous, which significantly hinders the further developments of highly efficient electrocatalysts based on structural reconstruction chemistry. In this review, a comprehensive overview of the structural reconstruction behaviors in the reported reconstruction‐derived electrocatalysts is provided and the intrinsic chemical and structural origins of their high efficiency toward OER are unveiled. The fundamentals of structural reconstruction mechanisms, along with the recommended characterization techniques for the understanding of the dynamic structural reconstruction process and analyzing the structure of real catalytic species are also interpreted. Finally, in view of structural reconstruction chemistry, the potential perspectives to facilitate the design and synthesis of highly efficient and durable OER electrocatalyst are presented.

How to increase energy storage capability is one of the fundamental questions, it requires a deep understanding of the electronic structure, redox processes, and structural evolution of electrode materials. These thorny problems now usually involve spin-orbit, spin-related electron configuration, etc., which cannot be probed using conventional testing techniques. Considering the intimate connection between spin and magnetic properties, using electron spin as a probe, magnetic measurements make it possible to analyze energy storage processes from the perspective of spin and magnetism. Owing to the capability of characterizing spin properties and high compatibility with the energy storage field, magnetic measurements are proven to be powerful tools for contributing to the progress of energy storage. In this review, several typical applications of magnetic measurements in alkali metal ion batteries research to emphasize the intimate connection between the magnetic properties and electronic structure, which is associated with the electrochemical performance of the electrode materials, are presented. Finally, the current challenges of magnetic measurements and the prospects for enhanced analysis of energy storage systems are discussed.

“…More recently, versatile spin electrocatalysis has been in full swing and helped integrate a comprehensive understanding of sulfur redox. [109][110][111][112] Meanwhile, our group took full advantage of spinel-type electrocatalysts with tetrahedral (Td) and octahedral (Oh) configuration simultaneously, plowing a universal concept of geometrical-site-dependent electrocatalytic activity to enrich the scope of applications for spin manipulation (Figure 4D). [103] Once Mn 3+ is incorporated into Oh sites in antiferromagnetic Co Oh -O-Co Td backbones, the originally located Co 3+ Oh is driven into Td sites to construct ferromagnetic Mn 3+ Oh -O-Co 3+ Td backbones instead.…”

The chief culprit impeding the commercialization of lithium–sulfur (Li–S) batteries is the parasitic shuttle effect and restricted redox kinetics of lithium polysulfides (LiPSs). To circumvent these key stumbling blocks, incorporating electrocatalysts with rational electronic structure modulation into sulfur cathode plays a decisive role in vitalizing the higher electrocatalytic activity to promote sulfur utilization efficiency. Breaking the stereotype of contemporary electrocatalyst design kept on pretreatment, field‐assisted electrocatalysts offer strategic advantages in dynamically controllable electrochemical reactions that might be thorny to regulate in conventional electrochemical processes. However, the highly interdisciplinary field‐assisted electrochemistry puzzles researchers for a fundamental understanding of the ambiguous correlations among electronic structure, surface adsorption properties, and catalytic performance. In this review, the mechanisms, functionality explorations, and advantages of field‐assisted electrocatalysts including electric, magnetic, light, thermal, and strain fields in Li–S batteries have been summarized. By demonstrating pioneering work for customized geometric configuration, energy band engineering, and optimal microenvironment arrangement in response to decreased activation energy and enriched reactant concentration for accelerated sulfur redox kinetics, cutting‐edge insights into the holistic periscope of charge‐spin‐orbital‐lattice interplay between LiPSs and electrocatalysts are scrutinized, which aspires to advance the comprehensive understanding of the complex electrochemistry of Li–S batteries. Finally, future perspectives are provided to inspire innovations capable of defeating existing restrictions.
