1. Pore-Size Dominated Electrochemical Properties of Covalent Triazine Frameworks as Anode Materials for K-ion Batteries

Chem. Sci., 2019, Advance Article

DOI: 10.1039/C9SC02340B

A team of researchers from Northeast Normal University and Shandong Normal University have made two homologous covalent triazine frameworks (CTFs) as anode materials for K-ion batteries. They find that the 2D sheetlike structure and the regular channels in the CTFs enable the intercalation/deintercalation of K-ions into/from the CTF interlayers. Additionally, the electrochemical performance relates closely to the pore size of the frameworks. The work provides a promising strategy for the rational design of high performance organic anode materials for high performance K-ion batteries.

东北师范大学和山东师范大学的研究小组合成了两种同源共价三嗪骨架（CTFs），可作为钾离子电池的负极材料。他们发现这种二维片状结构以及 CTFs中的规则通道可以使钾离子可逆地嵌入/脱离CTF夹层。此外，电化学性能与框架的孔大小密切相关。该研究为合理设计高性能钾离子电池中的有机负极材料提供了一种有前景的策略。

2. Structural and Defect Engineering of Cobaltosic Oxide Nanoarchitectures as Ultrahigh Energy Density and Super Durable Cathode for Zn-based Batteries

Chem. Sci., 2018, Advance Article

DOI: 10.1039/C9SC01902B

Scientists from Sun Yat-Sen University have prepared a 3D ordered mesoporous nanoarchitecture, cobaltosic oxide with rich oxygen vacancies (M-Co₃O_4-x) as a cathode material for rechargeable Zn-based batteries (ZBBs). Using experimental and DFT studies they show that the energy storage capacity is significantly enhanced by the synergistic effect of mesopores and O vacancies. The material achieved a remarkable capacity of 384 mAh/g at 1.0 A/g and cycling stability of 6000 at 1 A/g and 60000 at 10 A/g. Such high cycling stability has never been reported before in ZBBs and the capacity outperforms most previously reported ZBBs.

中山大学的研究人员制备了一种三维有序的介孔纳米结构，这种具有丰富氧空位的四氧化三钴（M-Co₃O_4-x）可以作为可充电锌基电池的正极材料。实验和DFT计算表明，介孔和氧空位的协同效应显著提高了储能容量。该材料在1.0 A/g条件下达到了384 mAh/g的高容量，循环稳定性在1 A/g和10 A/g条件下分别为6000和60000次。先前报道的锌基电池中从未有过如此高的循环稳定性，且容量也优于大多数此前报道的锌基电池。
