Section 2 of 5Battery Chemistry Types
Battery chemistry refers to the specific materials and electrochemical reactions used to store and release electrical energy. Each chemistry represents a different balance of performance characteristics, cost, safety, and environmental impact. The choice of chemistry depends on the specific application requirements.
Modern battery chemistries have evolved from simple lead-acid systems to sophisticated lithium-based technologies. Emerging chemistries like sodium-ion and lithium-sulfur promise to overcome current limitations in energy density, cost, and resource availability.

Chemistry Selection Trade-offs
Energy vs Power: High energy density chemistries typically have lower power density and vice versa.
Safety vs Performance: Safer chemistries often have lower energy density and higher costs.
Cost vs Longevity: Lower-cost chemistries may have shorter cycle life or lower energy density.
Application Matching: Choose chemistry based on specific requirements - EVs need high energy/power density, grid storage prioritizes cycle life and safety.
