新型储能技术发展与展望

Development and Outlook of New Technologies for Energy Storage

储能技术是构建新型电力系统,实现双碳目标的关键环节。传统的抽水蓄能技术不能完全解决由风光为主的新能源发电不稳定造成的问题,新型储能技术由此应运而生,多元化的储能技术不断发展。本文通过基本原理、发展现状、前沿技术分析和发展展望四个方面,详细总结了锂离子电池、液流电池、钠离子电池、压缩空气储能这几种主流的、未来有巨大发展潜力的新型储能技术。最后,对新型储能技术未来发展趋势进行了分析。

Energy storage technology is crucial for building the new-type power system and achieving the carbon peaking and carbon neutrality goals.The traditional pumped-storage technology cannot completely solve the instability problems of power generation of new energies such as the wind and photovoltaic power,etc.That’s where the new technologies for energy storage come in,become diversified and continue developing.From the four aspects,i.e.,basic principle,development status,analysis on cutting-edge technologies and prospect of development,the mainstream new technologies for energy storage with great potential for development in the future,such as the lithium-ion batteries,flow batteries,sodium-ion batteries and compressed air energy storage,are summarized in detail in this paper.The future development trends of new technologies for energy storage is also analyzed.
