Defect engineering of vanadium-based electrode materials for zinc ion battery

Chinese Chemical Letters 2023年第7期34卷 78-86页

作者： ying Liu Yi Liu Xiang wu School of Materials Science and Engineering Shenyang University of TechnologyShenyang 110870China

With the quick development of sustainable energy sources, aqueous zinc-ion batteries(AZIBs) have become a highly potential energy storage technology. It is a crucial step to construct desired electrode materials for improving the total performance of AZIBs. In recent years, considerable efforts have focused on the modification of vanadium-based cathode materials. In this review, we summarized defect engineering strategies of vanadium-based cathodes, including oxygen defects, cation vacancies and heterogeneous doping. Then, we discussed the effect of various defects on the electrochemical performance of electrode materials. Finally, we proposed the future challenges and development directions of V-based cathode materials.

Multi-electron reaction and fast Al ion diffusion of δ-MnO_(2) cathode materials in rechargeable aluminum batteries via first-principle calculations

引用

Chinese Chemical Letters 2024年第4期35卷 248-254页

作者： Lumin Zheng ying Bai Chuan wu School of Materials Science&Engineering Beijing Institute of TechnologyBeijing 100081China Yangtze Delta Region Academy of Beijing Institute of Technology Jiaxing 314019China

Rechargeable aluminum batteries with multi-electron reaction have a high theoretical capacity for next generation of energy storage devices. However, the diffusion mechanism and intrinsic property of Al insertion into MnO_(2) are not clear. Hence, based on the first-principles calculations, key influencing factors of slow Al-ions diffusion are narrow pathways, unstable Al-O bonds and Mn^(3+) type polaron have been identified by investigating four types of δ-MnO_(2)(O3, O'3, P2 and T1). Although Al insert into δ-MnO_(2) leads to a decrease in the spacing of the Mn-Mn layer, P2 type MnO_(2) keeps the long(spacious pathways)and stable(2.007–2.030 A) Al-O bonds resulting in the lower energy barrier of Al diffusion of 0.56 e V. By eliminated the influence of Mn^(3+)(low concentration of Al insertion), the energy barrier of Al migration achieves 0.19 e V in P2 type, confirming the obviously effect of Mn^(3+) polaron. On the contrary, although the T1 type MnO_(2) has the sluggish of Al-ions diffusion, the larger interlayer spacing of Mn-Mn layer,causing by H_(2)O could assist Al-ions diffusion. Furthermore, it is worth to notice that the multilayer δ-MnO_(2) achieves multi-electron reaction of 3|e|. Considering the requirement of high energy density, the average voltage of P2(1.76 V) is not an obstacle for application as cathode in RABs. These discover suggest that layered MnO_(2) should keep more P2-type structure in the synthesis of materials and increase the interlayer spacing of Mn-Mn layer for providing technical support of RABs in large-scale energy storage.

由于环境污染具有负外部性,跨区域的环境问题不断涌现,因此,地方政府之间的合作治理是化解区域环境问题的重要路径,也是未来中国区域环境治理的发展方向。本文基于复杂网络理论、演化博弈理论,考虑地方政府间的偏好异质性和收入异质性,引入权重来刻画不同地区在合作中的贡献度的差异,并纳入收益分配机制、违约金机制,构建了加权NW小世界网络上地方政府间合作治理的演化博弈模型;通过数值仿真,分析了合作收益和成本、违约金、异质性三方面对网络合作水平的影响。研究结果表明:合作收益增加与合作成本降低均能促进地方政府合作治理网络向着帕累托最优方向演化,且当合作收益和合作成本到达一定水平时,经济发展水平低的地区对合作收益和合作成本的变化更为敏感。适当的违约金可以促进地方政府合作行为的演化,但违约金只是起到保障和制约的作用,仅提高违约金难以促进合作策略全扩散。节点异质性对于提高地方政府区域合作治理水平是一把双刃剑。
