Battery Active Materials

Cathode and anode active materials for lithium-ion, sodium-ion, fast-charge, high-energy, and pilot-scale cell development.

Materials Covered

Winigen Materials can support RFQ-based sourcing for cathode and anode powders used in electrode formulation, cell screening, and material down-selection.

  • LFP, LMFP, LMO, LNMO, LCO, NMC, and NCA cathode materials
  • Lithium metal foil, graphite, LTO, hard carbon, silicon, SiOx, and Si-C anode materials
  • Typical SDS, COA, and TDS support depending on material and lot

Specification Guidance

Values shown on the cards are typical commercial specification ranges. Final quotes should confirm grade, morphology, particle-size distribution, capacity, initial efficiency, moisture, packaging, and documents.
