Lfp vs Ncm Battery Chemistry: Why Tesla's Switch Matters for Grid StorageTechnical comparison of Lithium Iron Phosphate (LFP) and Nickel Cobalt Manganese (NCM) battery chemistries for grid-scale energy storage applications.

NCM batteries provide 1.5-2x higher energy density than LFP, which should reduce land requirements and installation costs. Why do grid storage projects increasingly choose LFP despite the space penalty?
Additional Context
Energy density matters less for stationary storage than automotive applications. The 25-40% lower LCOS from LFP's superior cycle life (6000+ vs 2000+ cycles) apparently outweighs the space penalty. But as land costs increase in urban areas, will this calculation change?

•Battery Technology Researcher, TeslaGrid storage economics heavily favor cycle life over energy density. A typical utility-scale project cycles daily for 20 years (7300 cycles). NCM would require mid-life replacement, essentially doubling the total system cost. Land costs are typically <5% of total project cost, so the space penalty for LFP is economically irrelevant compared to the cycle life advantage.
