Lithium-Ion Technologies
LFP (Lithium Iron Phosphate) dominates commercial storage with superior safety and 6,000+ cycles. NMC offers higher energy density but shorter lifespan. LFP costs $400-600/kWh installed.
Alternative Technologies
Flow batteries offer 10,000+ cycles and 20-year life but cost 30-50% more. Sodium-ion emerging as lower-cost alternative. Mechanical storage suitable for specific applications.
Performance Comparison
Compare round-trip efficiency (85-95%), response time, depth of discharge, and degradation rates. LFP offers best balance of performance, safety, and cost for most applications.
