Core Viewpoint - The article discusses the recent price increases in energy storage cells and systems, driven by rising lithium carbonate prices and unexpected demand growth since the beginning of 2026 [2][3]. Price Trends of Energy Storage Cells - The average price of energy storage cells has increased by 0.025 yuan/Wh since January 2026, with significant price hikes across all specifications [3]. - The price of battery-grade lithium carbonate rose from 119,500 yuan/ton on January 1 to 171,000 yuan/ton by January 23, before fluctuating and rebounding to over 180,000 yuan/ton in mid-February [3]. - The price increases in energy storage cells are particularly pronounced for the 100Ah and 314Ah specifications, with the latter's price approaching 0.4 yuan/Wh, reflecting a 5%-8% increase from January [12]. Specific Price Changes by Specification - 50Ah cells: February average price at 0.416 yuan/Wh, up 0.009 yuan/Wh from January [9]. - 100Ah cells: February average price at 0.391 yuan/Wh, up 0.024 yuan/Wh from January [10]. - 280Ah cells: February average price at 0.321 yuan/Wh, up 0.015 yuan/Wh from January [11]. - 314Ah cells: February average price at 0.336 yuan/Wh, up 0.025 yuan/Wh from January, with significant price differentiation among manufacturers [12]. Impact on Energy Storage Systems - The rising costs of energy storage cells are expected to increase the overall costs of energy storage systems by approximately 5% if cell costs rise by 10% [13]. - The average price of grid-side energy storage systems has increased from 0.46 yuan/Wh in November to 0.52 yuan/Wh in mid-February [13]. - The highest bid price for 2-hour energy storage systems reached 0.6152 yuan/Wh in January 2026, indicating a strong upward trend in system pricing [16]. Market Dynamics and Competitive Landscape - The pressure from rising cell prices is leading to a divergence in pricing strategies among energy storage system manufacturers, with leading firms likely to raise prices due to stronger bargaining power [18]. - Smaller firms lacking core technology and cost control may continue to struggle in a low-price competition environment, facing potential market exit risks [18].
