Metal-ion(Li-,Na-,Zn-,K-,Mg-,and Al-ion)batteries(MIBs)play an important role in realizing the goals of“emission peak and carbon neutralization”because of their green production techniques,lower pollution,high voltage,and large energy density.carbon-based materials are indispensable for developing MIBs and are widely adopted as active or auxiliary materials in the anodes and cathodes.For example,carbon-based materials,includ-ing graphite,Si/C and hard carbon,have been used as anode materials for Li-and Na-ion batteries.carbon can also be used as a conductive coating for cathodes,such as in LiFePO 4/C,to achieve better performance.In addition,as new high-valence MIBs(Zn-,Al-,and Mg-ion)have emerged,a growing number of novel carbon-based mate-rials have been utilized to construct high-performance MIBs.Herein,we discuss the recent development trends in advanced carbon-based materials for MIBs.The impact of the structure properties of advanced carbon-based materials on energy storage is addressed,and a perspective on their development is also proposed.

Developing electrochemical energy storage devices with high energy and power densities,long cycling life,as well as low cost is of great significance.Hybrid metal-ion capacitors(MICs),commonly consisting of high energy battery-type anodes and high power capacitor-type cathodes,have become a trade-off between batteries and supercapacitors.Tremendous efforts have been devoted to searching for high-performance electrode materials due to poor rate capability of anodes,low capacity of cathodes,and interior sluggish kinetic match.carbon materials with large surface area,good electrical conductivity and stability have been considered to be ideal candidates for electrodes of MICs.In this review,the advanced carbon materials directly as cathodes and anodes of MICs are systematically summarized.Then,the key structural/chemical factors including the structure engineering,porous characteristics,and heteroatom incorporation for improving electrochemical performance of carbon materials are highlighted.Additionally,the challenges and opportunities for future research on carbon materials in MICs are also proposed.

作者： Yanying Shi Guijing Liu Rencheng Jin Hui Xu Qingyao Wang Shanmin Gao School of Chemistry and materials Science Ludong UniversityYantaiChina

With the increasing energy demand together with the deteriorating environment and decreasing fossil fuel resources,the development of highly efficient energy conversion and storage devices is one of the key challenges of both fundamental and applied research in energy technology.Melamine sponges(MS)with low density,high nitrogen content,and high porosity have been used to design and obtain three‐dimensional porous carbon electrode materials.More importantly,they are inexpensive,environment‐friendly,and easy to synthesize.There have been many reports on the modification of carbonized MS and MS‐based composites for supercapacitor and lithium battery electrode materials.In this paper,recent studies on the fabrication of electrode materials using MS as raw materials have been mainly reviewed,including carbonation,doping activation,and composite modification of MS,and expectations for the development of porous carbon materials for energy storage as a reference with excellent performance,environment‐friendliness,and long life.

Lithium(Li)metal is regarded as the ultimate anode for next-generation Li-ion batteries due to its highest specific capacity and lowest electrochemical potential.However,the Li metal anode has limitations,including virtually infinite volume change,nonuniform Li deposition,and an unstable electrode-electrolyte interface,which lead to rapid capacity degradation and poor cycling stability,significantly hindering its practical application.To address these issues,intensive efforts have been devoted toward accommodating and guiding Li deposition as well as stabilizing the interface using various carbon materials,which have demonstrated excellent effectiveness,benefiting from their vast variety and excellent tunability of the structure-property relationship.This review is intended as a guide through the fundamental challenges of Li metal anodes to the corresponding solutions utilizing carbon materials.The specific functionalities and mechanisms of carbon materials for stabilizing Li metal anodes in these solutions are discussed in detail.Apart from the stabilization of the Li metal anode in liquid electrolytes,attention has also been paid to the review of anode-free Li metal batteries and solid-state batteries enabled by strategies based on carbon materials.Furthermore,we have reviewed the unresolved challenges and presented our outlook on the implementation of carbon materials for stabilizing Li metal anodes in practical applications.

Hierarchically porous zeolites are promising candidates in catalytic conversion of relatively bulky molecules,and their syntheses have attracted significant attention.From both industrial and scientific perspectives,different carbon materials have been widely employed as hard templates for the preparation of hierarchically porous zeolites during the past two decades.In this review,the progress in synthetic strategies using carbon materials as templates is comprehensively summarized.Depending on the affinity between the carbon templates and zeolite precursors,the substantial strategies for synthesizing hierarchical zeolites are introduced in direct templates and indirect templates.Direct templates methods,by which the carbon materials are directly mixed with precursors gel as hard templates,are first reviewed.Then,we discuss the indirect templates method(crystallization of carbon-silica composites),by which the carbon is produced by in situ pyrolysis of organic-inorganic precursors.In addition,the technique of encapsulating metal species into zeolites crystals with the assistance of carbon templates is also discussed.In the conclusion part,the factors affecting the synthesis of carbon-templated hierarchically porous zeolites are remarked.This review is expected to attract interest in the synthesis strategies of hierarchically porous zeolites,especially cost-effective and large-scale production methodologies,which are essential to the industrial application of hierarchical zeolites.

Inorganic p-type semiconductors and carbon materials based hole transport materials for perovskite solar cells

引用

Chinese Chemical Letters 2018年第8期29卷 1242-1250页

作者： Yang Yang Ngoc Duy Pham Disheng Yao Huaiyong Zhu Prasad Yarlagadda Hongxia Wang School of Chemistry Physics and Mechanical Engineering Queensland University of Technology

Organic-inorganic lead halide based perovskite solar cells（PSCs） have presented a promising prospective in photovoltaic field with current record power conversion efficiency of 22.7%, which is comparable to commercial crystalline silicon cells and even higher than traditional thin film solar cells of CIGS. However,the pressure to enhance device stability under operational condition has driven researches towards development of stable hole transport materials（HTMs） for PSCs. Compared to traditional expensive organic HTMs such as spiro-OMeTAD, there is no doubt that inorganic p-type semiconductors and carbon materials are attractive alternatives that not only possess better stability but also are much cheaper. This review summarized the most recent progress of inorganic hole-transporting materials and carbon materials that have been developed for PSCs. The most recent advancement of device performance using these HTMs was demonstrated. In addition, the research of using various types of carbon materials as additives in HTMs to enhance device performance and stability or as electrical contact in HTM-free PSC was also demonstrated. The effectiveness of each type of materials on mitigating ion migration and degradation of PSC induced by humidity, illumination light intensity and high temperature is discussed.This timely review sheds light on the approaches to tackle the stability issue of PSCs to push the technology towards commercialization through material engineering of HTM.
