However, it still remains a challenge to obtain a high-performance hard carbon anode from cost-effective carbon sources.

Herein, a lignin-based hard carbon with robust SEI is developed to address these issues, effectively killing two birds with one stone. An innovative gas-phase removal-assisted aqueous washing strategy is developed to remove excessive sodium in the precursor to upcycle industrial lignin into high-value hard carbon, which demonstrated an ultrahigh sodium storage capacity of 359 mAh g<sup>−1</sup>. It is found that the residual sodium components from lignin on hard carbon act as active sites that controllably regulate the composition and morphology of SEI and guide homogeneous SEI growth by a near-shore aggregation mechanism to form thin, dense, and organic-rich SEI.

However, how to improve its low capacity and stability, and slow diffusion kinetics during lithium storage remains a challenge. In this research, we propose a “self-assembly-template” method to prepare B, N codoped porous carbon (BN-C) with a nanosandwich structure and abundant pyridinic N-B species. The nanosandwich structure can increase powder density and cycle stability by constructing a stable solid electrolyte interphase film, shortening the Li<sup>+</sup> diffusion pathway, and accommodating volume expansion during repeated charging/discharging. The abundant pyridinic N-B species can simultaneously promote the adsorption/desorption of Li<sup>+</sup>/PF<sub>6</sub><sup>−</sup> and reduce the diffusion barrier. The BN-C electrode showed a high lithium-ion storage capacity of above 1140 mAh g<sup>−1</sup> at 0.05 A g<sup>−1</sup> and superior stability (96.5% retained after 2000 cycles). Moreover, owing to the synergistic effect of the nanosandwich structure and pyridinic N-B species, the assembled symmetrical BN-C//BN-C full cell shows a high energy density of 234.7 W h kg<sup>−1</sup>, high power density of 39.38 kW kg<sup>−1</sup>, and excellent cycling stability, superior to most of the other cells reported in the literature. As the density functional theory simulation demonstrated, pyridinic N-B shows enhanced adsorption activity for Li<sup>+</sup> and PF<sub>6</sub><sup>−</sup>, which promotes an increase in the capacity of the anode and cathode, respectively. Meanwhile, the relatively lower diffusion barrier of pyridinic N-B promotes Li<sup>+</sup> migration, resulting in good rate performance. Therefore, this study provides a new approach for the synergistic modulation of a nanostructure and an active site simultaneously to fabricate the carbon electrode material in energy storage devices.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":null,"pages":null},"PeriodicalIF":19.5,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.511","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140202117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we synthesize metal–organic framework-derived carbon microcapsules with heteroatom clusters (Zn and Ag) on the capsule walls and it is demonstrated that Ag-assisted nucleation of Li metal alters the outward-to-inward growth in the microcapsule host. Zn-incorporated microcapsules are prepared via chemical etching of zeolitic imidazole framework-8 polyhedra and are subsequently decorated with Ag by a galvanic displacement reaction between Ag<sup>+</sup> and metallic Zn.

Experimental results and charge density difference plots indicate that the active site of CO<sub>2</sub>RR is the positively charged carbon atom adjacent to graphitic N on 1D carbon and the active site of HER is the pyridinic N on 1D carbon. The presence of pyridinic N and pyrrolic N reduces the number of electron transfer, decreasing the reaction kinetics and the activity of CO<sub>2</sub>RR. The CO/H<sub>2</sub> ratio is related to the distribution of N species and the specific surface area, which are determined by the degree of spatial confinement effect.

Nevertheless, the persistent challenge of uneven Mg electrodeposition remains a significant impediment to their practical integration. Herein, we developed an ingenious approach that centered around epitaxial electrocrystallization and meticulously controlled growth of magnesium crystals on a specialized MgMOF substrate. The chosen MgMOF substrate demonstrated a robust affinity for magnesium and showed minimal lattice misfit with Mg, establishing the crucial prerequisites for successful heteroepitaxial electrocrystallization. Moreover, the incorporation of periodic electric fields and successive nanochannels within the MgMOF structure created a spatially confined environment that considerably promoted uniform magnesium nucleation at the molecular scale. Taking inspiration from the “blockchain” concept prevalent in the realm of big data, we seamlessly integrated a conductive polypyrrole framework, acting as a connecting “chain,” to interlink the “blocks” comprising the MgMOF cavities. This innovative design significantly amplified charge-transfer efficiency, thereby increasing overall electrochemical kinetics. The resulting architecture (MgMOF@PPy@CC) served as an exceptional host for heteroepitaxial Mg electrodeposition, showcasing remarkable electrostripping/plating kinetics and excellent cycling performance. Surprisingly, a symmetrical cell incorporating the MgMOF@PPy@CC electrode demonstrated impressive stability even under ultrahigh current density conditions (10 mA cm<sup>–2</sup>), maintaining operation for an extended 1200 h, surpassing previously reported benchmarks.
