Reference: 2024 global average pack price ~ $0. 115/Wh, the largest annual drop since 2017, driven by LFP adoption, lower materials, and overcapacity. This cost estimate, an average of NMC and LFP pack costs, is derived using updated material prices and the peer reviewed, publicly available BatPaC battery cost modeling software developed at Argonne National. . In 2023, battery electric vehicle packs averaged $128 per kWh. Lithium-ion batteries ranged from $10 to $20,000. 115/Wh globally in 2024 (down ~20% YoY), but finished consumer systems (portable power stations) retail much higher due to inverters, BMS, certifications, and margins. Battery Chemistry Different battery chemistries come with varying costs and performance characteristics: Lithium-Ion (Li-ion): Known for high energy density. . Raw materials represent the largest share of lithium battery expenses, typically accounting for 50–70% of the total cost. Among these, the cathode materials dominate, contributing around 35–45% depending on the battery chemistry.
