“…[96] The ionic conductivity is questionable too. [102,103] The electrochemical reaction in sulfur is very different from that of conversion materials discussed earlier, as can be seen in Figure 13b where the formation and shuttle of polysulfides are highlighted. Not only the electron diffusion length is greatly reduced but also direct electron tunneling is possible at such a length scale, leading to appreciable electronic conductivity.…”

Driven by the increasing demand for electrochemical energy storage, lithium ion and lithium batteries have been the subject of tremendous scientific endeavors for decades. However, limited energy density, which is bottlenecked by available high-density cathode materials, has become a critical issue to be solved. Recently, computational studies have played an increasingly important role in the search for the next-generation high-density cathode materials. Not only important insights on the battery chemistry have been revealed, but also novel material systems have been proposed. This review highlights recent progresses in the computational studies of cathode materials for lithium ion and lithium batteries. It starts from a brief introduction of the scientific background of lithium ion and lithium batteries, followed by a brief discussion of the working principles of batteries. Different computer simulation techniques are shown to originate from the same quantum mechanical treatment of many-body systems with different levels of simplifications. Progresses in computational studies of different cathode materials, including intercalation electrode, conversion compounds, sulfur, and organosulfides, are then presented in detail. Finally, the capabilities of computational techniques in the study of cathode materials are summarized, and major challenges are discussed. REVIEW Lithium Ion Batteries

Three-dimensional multi-doped porous carbon/graphene (Fe-Mt-SS-C) was prepared by carbonization of sewage sludge with template-assisted Fe-pillared montmorillonite. The material consisted of nanosheet- and particle- carbon had a high specific surface area (784.46 m2·g−1) and hierarchical porous structure of micro-, meso- and macropores. The prepared Fe-Mt-SS-C had a high degree of graphitization and large amount of defect atoms. The pyrolysis process made full use of the C, N, Fe, and S by turning them into the carbon framework of the as-obtained material in situ. Template-assisted Fe-pillared montmorillonite contributed to more characteristics of morphology and composition on Fe-Mt-SS-C than other three materials (SS-C, Mt-SS-C and Fe-SS-C), and enhanced the electrocatalytic ORR activity by providing more adsorption sites and the electronic structure, resulting in the increase of conductivity and electrochemical activity. The ORR activity performance of Fe-Mt-SS-C, including the value of onset potential (0.03 V) and E1/2 (−0.09 V), was better than that of commercial 20 wt% Pt/C (−0.02 V and −0.18 V, respectively). Moreover, the Fe-Mt-SS-C possessed excellent durability and outstanding immunity toward methanol crossover effects. Therefore, the resultant Fe-Mt-SS-C has great potential to applied as a high-efficiency ORR electrocatalyst, more importantly, it realizes the utilization of the sludge at the same time.

As one of the alternatives to replace precious metal catalysts, transition-metal-nitrogen-carbon (M-N-C) electrocatalysts have attracted great research interest due to their low cost and good catalytic activities. Despite nanostructured M-N-C catalysts can achieve good electrochemical performances, they are vulnerable to aggregation and insufficient catalytic sites upon continuous catalytic reaction. In this work, metal-organic frameworks derived porous single-atom electrocatalysts (SAEs) were successfully prepared by simple pyrolysis procedure without any further posttreatment. Combining the X-ray absorption near-edge spectroscopy and electrochemical measurements, the SAEs have been identified with superior oxygen reduction reaction (ORR) activity and stability compared with Pt/C catalysts in alkaline condition. More impressively, the SAEs also show excellent ORR electrocatalytic performance in both acid and neutral media. This study of nonprecious catalysts provides new insights on nanoengineering catalytically active sites and porous structures for nonprecious metal ORR catalysis in a wide range of pH.
