Understand costs to guide battery design and economics with Fastmarkets' Battery Cost Index, which gives you pricing granularity for existing battery materials. Find out more here.
The Fastmarkets Battery Cost Index is an easy-to-use cost model for total cell costs, including cost breakdown of active anode material (AAM), cathode active material (CAM), separator, electrolyte, other materials, energy, labor and operational costs across multiple chemistries and geographies.
Volatile battery raw material prices, varying battery chemistries and differing manufacturing costs result in cell prices that appear opaque and subjective. This makes it difficult for market participants to budget effectively, anticipate price changes, bring transparency to transactions and effectively track cost changes over time.
