Cycle Life (Cycles)
Cost (USD/kWh)

Lithium-Ion	150-250	500-1000	100-200
Solid-State	250-500	800-1500	80-150 (projected)
Sodium-Ion	100-150	500-1000	50-100

The table above provides a comparative overview of different battery chemistries, highlighting the trade-offs between energy density, cycle life, and cost. As you can see, solid-state batteries offer the potential for significantly higher energy density and longer cycle life, but their cost is currently higher than that of lithium-ion. Sodium-ion batteries, on the other hand, offer a more sustainable alternative to lithium-ion due to the abundance of sodium, but their energy density is lower.

Beyond Lithium: Exploring Alternative Chemistries

The search for alternatives to lithium-ion has led to the development of several promising battery chemistries, each with its unique advantages and disadvantages. Sodium-ion batteries, leveraging the widespread availability of sodium, are garnering increasing attention as a cost-effective and sustainable option for stationary energy storage.
