This paper systematically reviews the application of manganese dioxide (MnO2) in the field of energy storage and conversion in terms of preparation techniques, modification strategies and device performance. Firstly, the regulation mechanisms of liquid-phase method, solid-phase method, sol-gel method, microfluidic etching and other approaches on the micromorphology and crystal structure of MnO2 are elaborated systematically. As for modification strategies, the functional mechanisms of element doping, carbon-based material compositing and microstructure design (including nanostructuring and hollow structure) for improving the electrical conductivity and structural stability of materials are discussed in detail. In the aspect of device performance, the practical effects of MnO2-based composites on elevating the specific capacity of lithium-ion batteries, optimizing the rate performance of supercapacitors, and boosting the catalytic activity of bifunctional electrocatalysts (ORR and OER) are further analyzed. On this basis, future development prospects are proposed from the perspectives of green synthesis technologies, high-loading flexible device development and multi-functional integration, aiming to provide references for the rational design of high-performance MnO2-based energy materials.

围绕二氧化锰(MnO2)在能源存储与转换领域的应用,从制备技术、改性策略到器件性能三个递进层面展开系统综述。在制备技术层面,系统阐述了液相法、固相法、溶胶-凝胶法及微流控刻蚀等技术对MnO2微观形貌与晶体结构的调控机制;在改性策略层面,详细探讨了元素掺杂、碳基材料复合及微观结构设计(如纳米化、空心结构)等策略提升材料导电性与结构稳定性的作用机理;在器件性能层面,进一步分析了MnO2基复合材料在提升锂离子电池比容量、优化超级电容器倍率性能以及增强双功能催化剂(ORR/OER)活性等方面的具体成效。在此基础上,从绿色合成技术、高负载柔性器件开发及多功能集成等角度提出未来发展建议,以期为高性能MnO2基能源材料的科学设计提供参考。

This paper systematically reviews the application of manganese dioxide (MnO2) in the field of energy storage and conversion in terms of preparation techniques, modification strategies and device performance. Firstly, the regulation mechanisms of liquid-phase method, solid-phase method, sol-gel method, microfluidic etching and other approaches on the micromorphology and crystal structure of MnO2 are elaborated systematically. As for modification strategies, the functional mechanisms of element doping, carbon-based material compositing and microstructure design (including nanostructuring and hollow structure) for improving the electrical conductivity and structural stability of materials are discussed in detail. In the aspect of device performance, the practical effects of MnO2-based composites on elevating the specific capacity of lithium-ion batteries, optimizing the rate performance of supercapacitors, and boosting the catalytic activity of bifunctional electrocatalysts (ORR and OER) are further analyzed. On this basis, future development prospects are proposed from the perspectives of green synthesis technologies, high-loading flexible device development and multi-functional integration, aiming to provide references for the rational design of high-performance MnO2-based energy materials.
