Abstract: In the process of implementing the “dual-carbon”goal, energy storage plays an important role in supporting the load balance of new power systems mainly based on new energy sources, and new energy storage technologies have been receiving more attention due to their advantages of short construction period, high flexibility in siting, and strong regulating capability. This paper compares and analyzes the strategic planning layout of new energy storage technologies in major countries/regions such as the United States, the European Union, and Japan. For the six major technology directions of new energy storage technology, namely lithium-ion battery,sodium-ion battery, liquid flow battery, metal-air battery,compressed air energy storage, and gravity energy storage, the literature measurement and patent measurement methods are utilized to deeply excavate and analyze the cutting-edge themes and innovation ability in this field at home and abroad. The results show that China’s R＆D and innovation ability in the field of new energy storage technology is overall strong. From the statistics of paper achievements, China has published more than 70,000 papers in this technology field, ranking first in the world,accounting for 53.5% of the total number of papers published in the world. From the statistics of patent achievements, China has been the most important source country of patented technology in the field of new energy storage from 2020 to 2022, and the number of invention patents and high-value patent applications accounted for more than 80% of the global total, but the output rate of high-value patents is slightly lower than the global average level.
