Critical Mineral

Manganese

Stabilizing high-energy cathodes.

Manganese improves the stability and cost profile of many cathode chemistries, from LFP variants to high-energy NMC blends.

Role in the battery value chain

Boosts structural stability in layered oxides and high-manganese cathodes.
Helps reduce reliance on higher-cost or higher-risk metals such as cobalt.
Supports emerging cathode families that balance energy, cost, and safety.

From ore to battery-grade material

Manganese ores are processed into high-purity manganese sulfate and other salts used in cathode precursor plants. Impurity control is critical to ensure long-term cell performance.

National security & resilience

Building a resilient manganese sulfate supply, including domestic refining and allied sourcing, is key to scaling next-generation cathodes in the U.S.

Environmental & community considerations

Improved process design, waste minimization, and recycling of process streams reduce the environmental intensity of manganese refining.

The American Battery connects manganese to the full lithium-ion value chain—from mining and refining through active materials, cells, packs, and recycling—so that policymakers, partners, and citizens can see how this element supports American energy security.
