Abstract

There has been a search for new supercapacitor materials that offer superior storage qualities during the past ten years, owing to the needs of the electrochemical energy storage sector. Supercapacitors, which have a higher power density than batteries but a lower energy density, are among the most promising energy storage technologies. Creating innovative materials that increase energy storage efficiency is essential to fulfilling the world's growing energy needs. Recent research has centred on the application of various electrode materials in supercapacitors. This review discusses the parameters of an efficient supercapacitor and the usage of metal oxynitrides as electrode materials. Due to their high cyclability (up to 10⁵ cycles), strong intrinsic conductivity (30000–35000 S cm⁻¹), good wettability, corrosion resistance, and chemical inertness, metal oxynitrides are considered prospective candidates for electrochemical energy storage. This review elaborates on the recent advances in transition metal oxynitrides and compares the properties of transition metal oxynitrides with post-transition and non-transition metal oxynitrides in supercapacitor applications. We envision future paths for this category of energy storage materials in light of this critical study.

超级电容器用金属氮氧化物的研究进展与展望

在过去的十年里，由于电化学储能领域的需要，人们一直在寻找能够提供卓越存储质量的新型超级电容器材料。超级电容器具有比电池更高的功率密度，但能量密度较低，是最有前途的储能技术之一。创造能够提高能源储存效率的创新材料对于满足世界日益增长的能源需求至关重要。最近的研究集中在各种电极材料在超级电容器中的应用。本文综述了高效超级电容器的参数及金属氮氧化物作为电极材料的应用。由于其高可循环性(高达105次循环)，强固有电导率(30,000 - 35000 S cm−1)，良好的润湿性，耐腐蚀性和化学惰性，金属氮氧化物被认为是电化学储能的潜在候选者。本文综述了过渡金属氮氧化物的最新研究进展，并比较了过渡金属氮氧化物与后过渡金属氮氧化物和非过渡金属氮氧化物在超级电容器中的应用。根据这项重要的研究，我们设想了这类储能材料的未来发展道路。

期刊介绍： Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
