储能锂电大单潮起

Core Viewpoint - The energy storage lithium battery sector is becoming a significant growth area within the lithium battery industry, driven by increasing order volumes and capacity expansion as observed at the beginning of 2026 [2][11]. Market Performance and Trends - The Chinese energy storage lithium battery market is expected to experience explosive growth in 2025, with a projected shipment volume of 630 GWh, representing an 85% year-on-year increase, surpassing previous industry expectations [4]. - The mismatch between concentrated demand and delayed supply capacity has led to a tight supply situation, with some companies extending order backlogs into the first half of 2026 [4][7]. - The first half of 2025 saw a "buying spree" in the market, with high capacity utilization rates and some products being sold at a 30% premium due to supply-demand imbalances [4][7]. Order and Capacity Expansion - Major battery companies, including EVE Energy and CATL, have secured long-term supply agreements for hundreds of GWh of energy storage batteries, indicating a proactive approach to meet future market demand [5][6]. - The industry is entering a phase of accelerated capacity expansion, focusing on large-capacity battery production lines to align with signed long-term contracts [6][7]. Supply and Demand Dynamics - GGII forecasts that the energy storage battery market will add only 250-300 GWh of effective capacity in 2026, which may not sufficiently alleviate the existing supply-demand gap [7]. - Companies are increasingly engaging in contract manufacturing to manage short-term delivery pressures while optimizing resource allocation within the industry [7]. Demand Drivers - The domestic energy storage market is set to benefit from new growth points, including the establishment of approximately 100 national-level zero-carbon parks and the rising demand from AI computing centers for stable power supply [8][9]. - Significant investments exceeding 5 trillion yuan in the two major power grids will support renewable energy consumption and create a broader market for energy storage [9]. Future Projections - GGII predicts that the shipment volume of energy storage lithium batteries in China will exceed 850 GWh in 2026, with the absolute increase in the energy storage market expected to surpass that of power batteries for the first time [10]. - The growth in energy storage battery shipments is anticipated to positively impact the financial performance of several battery companies, with many reporting improved earnings forecasts for 2025 [10]. Industry Development Trends - The explosive growth of the energy storage lithium battery market in 2025, coupled with the ongoing order and capacity trends in 2026, indicates a shift towards a dual growth model in the lithium battery industry, encompassing both power and energy storage sectors [11].
