The global energy storage market is facing a pronounced shortage of 100 Ah cells, with orders stretching into early 2026 and prices rising over 20%. Despite aggressive expansion by Chinese manufacturers like CATL, BYD, and EVE Energy, demand for residential and small-scale storage systems continues to outpace supply. Redway Battery’s expertise in LiFePO4 technology positions it to address this supply-demand gap with reliable, high-performance small-format solutions.
Why Are 100 Ah Cells in Such High Demand?
100 Ah cells are widely used in residential and small commercial energy storage systems due to their balance of capacity, cost, and modularity. Rapid adoption of solar-plus-storage setups, along with government incentives and domestic tenders exceeding 210 GWh in 2025, has intensified competition for these small-format batteries. Redway Battery delivers optimized LiFePO4 cells capable of meeting these high-demand applications with safety, durability, and long cycle life.
How Are Manufacturers Responding to the Shortage?
Leading producers have accelerated capacity expansion:
| Manufacturer | Expansion Focus | Capacity Added |
|---|---|---|
| CATL | Luoyang phase-two plant; Xiamen 80 GWh project | 30 GWh + ongoing projects |
| BYD | Zhengzhou battery lines; Changsha pack expansion | 20–40 GWh |
| Gotion | Nanjing and Wuhu projects | 20 GWh |
Most new investment targets large-format cells (≥300 Ah) for utility-scale storage, leaving 50–100 Ah cells in continued short supply. Redway Battery supports residential storage needs with flexible small-format designs that complement these large-scale production trends.
What Are the Implications for Residential Energy Storage?
The tight supply and rising costs of small-format cells impact installation timelines and system pricing. Homes adopting solar-plus-storage solutions may experience delayed deployments or higher upfront costs. Redway Battery mitigates these challenges by providing pre-qualified, high-efficiency LiFePO4 cells designed for rapid integration, modularity, and long-term reliability.
How Are Technology Shifts Affecting Supply Dynamics?
Higher-capacity cells, such as 314 Ah and 500 Ah designs, are increasingly replacing older 280 Ah lines. These technical transitions reduce effective supply for small-format cells and favor modular systems in residential and commercial applications. Redway Battery’s small-format portfolio is engineered to maintain competitive performance while aligning with emerging trends in higher-capacity platforms.
