摘要
随着全球能源危机日趋严重,开发新型化学储能装置显得尤为重要。钠离子电容器由于特点鲜明而备受关注,成为当前研究的热点。但钠离子尺寸较大,脱嵌速率较慢,充放电过程中易产生较大体积变化,引起电极结构坍塌,导致了较差的循环稳定性和倍率性能,进而阻碍其实际应用。“双碳”型钠离子电容器缓解了钠离子电容器中普遍存在的两电极动力学匹配性不佳的问题,是当前研究的热点。对近年来国内外关于碳材料在钠离子电容器中的应用与发展进行了介绍。
With the increasing global energy crisis,it is very important to develop new chemical energy storage devices.Sodium(Na)-ion capacitor has attracted much attention because of its distinctive characteristics.However,due to the large size of Na ions,there is a large volume change in the process of charge and discharge and non-crystallization and slow de-intercalation rate,which leads to poor cycle stability and poor capacity retention.These issues greatly hinder the practical application of Na-ion capacitor.The dual-carbon Na-ion capacitor alleviates the problem of poor dynamic matching between two electrodes in Na-ion capacitor.In this paper,the preparation and electrochemical properties of porous carbon materials in sodium-ion capacitor was introduced.
