新能源储能与钒电池技术现状

Status quo of new energy storage and vanadium battery technology

新能源技术是21世纪最具潜力的技术之一,新型储能技术已成为新能源领域的重要组成部分,其技术发展水平直接影响新能源产业的发展。以锂离子电池、铅酸电池、液流电池为代表的新型电池产业增长迅猛,但其发展受技术、成本的限制,应用水平不一。钒氧化还原液流电池作为一种优良的绿色大规模储能设备,用作太阳能、风能发电过程的储能装置,电网调峰效果显著。本文分析了相关储能电池的技术特点、技术瓶颈,并基于钒电池研究应用现状,分析指出了钒电池技术发展的方向及有待解决的关键问题。

New energy storage technology has become an important part of the new energy field which is one of the most promising technologies of the 21 st century. Its technological level directly affects the development of new energy industry. Though lithium-ion batteries, lead-acid batteries and liquid batteries as the representatives of the new battery industry are growing rapidly, the development levels of application are constrained by the technology and cost in different degrees. The vanadium redox flow battery, as an excellent green large-capacity energy storage e- quipment, is used in energy storage devices for solar energy and wind power generation process, and its power grid peak regulation effect is remarkable. Based on the analysis of the technical characteristics, technical bottlenecks of relevant energy storage batteries, research and application status quo of vanadium batteries, this paper summarizes the development of vanadium battery technology and the key issues which should be solved.
