英媒：需求激增推动电池储能热潮，中韩企业开辟竞争新战线

Group 1 - The competition between Chinese and South Korean companies in the battery sector is expanding from electric vehicles to energy storage systems (ESS) due to the rising demand for renewable energy and data centers [1] - ESS helps stabilize the power grid by providing backup power, especially as the demand for clean technologies and AI-related hardware increases [1] - The share of energy storage batteries in the global battery market has increased from 5% in 2020 to 20%, with predictions of more than doubling by 2030 [1] Group 2 - Chinese energy storage batteries account for nearly 90% of the global ESS installed capacity, with over 80% market share in the US and over 75% in Europe [2] - Following the imposition of tariffs in the US, South Korean battery companies see an opportunity to regain market share, with LG Energy focusing on cost-effective lithium iron phosphate batteries for the US market [2] - The different trajectories of Chinese and South Korean energy storage companies illustrate a "tale of two battery markets" [2] Group 3 - In 2022, China exported lithium-ion batteries worth $15.3 billion to the US, widening the market share gap with competitors like South Korea [3] - Chinese lithium iron phosphate batteries are favored in the US for their competitive pricing and cost-effectiveness, particularly for data centers [3] - Despite high tariffs, Chinese exporters may withstand costs due to existing advantages, while South Korean manufacturers have yet to prove their ability to competitively produce lithium iron phosphate batteries at scale [3]
