为了减少温室气体排放，解决能源问题，韩国政府制定了可持续发展战略，加大政策支持和资金投入，重点扶植储能系统(energy storage system, ESS)产业。目前，韩国ESS设备产能和市场规模不断壮大，韩国企业在全球ESS市场占据了举足轻重的地位。在电化学储能系统领域，有关锂离子电池的研究主要集中在理想纳米结构和较大比表面积的纳米材料上；韩国企业自主开发的钠离子电池循环寿命长达15年，比传统电池的能量密度高3倍，有关氧化还原液流电池和超级电容器的研究尚处于起步阶段。

In order to reduce greenhouse gas emissions and solve the energy problem, the South Korean government has formulated a sustainable development strategy, increasing policy support and capital investment, focusing on supporting the energy storage system (ESS) industry. At present, the production capacity and market scale of Korean ESS equipment are growing, and Korean enterprises occupy a pivotal position in the global market. In the field of electrochemical energy storage systems, the research on lithium-ion batteries is mainly focused on ideal nanostructures and nanomaterials with large specific surface area; the cycle life of sodium-ion batteries developed by Korean enterprises is as long as 15 years, which is 3 times higher than that of traditional batteries, and the research on redox flow batteries and supercapacitors is still in its infancy.
