Which battery chemistries are commonly used in stationary storage and what are their trade-offs?

Stationary energy storage is all about long life, safety, and keeping costs under control since the system stays in one place and must endure many charge–discharge cycles. Lithium-ion chemistries fit that need well because they offer high round-trip efficiency, good calendar life, and a broad, scalable manufacturing base. Within lithium-ion, LiFePO4 provides excellent thermal stability and a long cycle life, making it a robust, safer choice for large installations. NMC offers higher energy density, so you can store more energy in a smaller or lighter package when space or weight is a concern. Together, these lithium-based options give a versatile balance of longevity, safety, and performance that aligns well with grid-scale or industrial storage needs. The other options have trade-offs that make them less favorable for widespread stationary storage. Lead-acid is inexpensive upfront but has a shorter cycle life and heavier weight, which increases total cost over time. Nickel-cadmium is durable but toxic and more expensive, with environmental and regulatory drawbacks. Flow batteries can achieve very long cycle life and easy scalability but typically come with lower energy density and higher upfront complexity and cost, limiting their ubiquity compared to lithium-based systems.
