What is BMLMP?
BMLMP stands for Bio-Mineralized Lithium Mixed Metals Phosphate — C4V's proprietary next-generation cathode chemistry. It is an advanced olivine cathode that builds upon LFP (lithium iron phosphate) by substituting a portion of iron with manganese and incorporating a Bio-Mineralization that stabilizes the crystal structure at higher voltages.
The result is a cathode that operates at approximately 4.0V nominal versus LFP's 3.4V — a 15–20% increase in energy density while retaining LFP's defining advantages: exceptional thermal stability, no oxygen release under stress, and a supply chain built on domestically abundant iron and manganese rather than expensive, geopolitically concentrated cobalt and nickel.
C4V reference cell C4V-53AH-27156146 (Rev K): 53 Ah, 3.7V nominal, 196 Wh. Operating window 2.8–4.1V with forced protections at 2.7V (over-discharge) and 4.2V (maximum charge). Continuous charge/discharge ≤1C, peak ≤10C. Over-current protection at 120A. Internal impedance ≤1 mΩ.
Supply Chain Advantage
BMLMP's supply chain story is one of the most compelling in advanced battery chemistry. Its two transition metals — iron and manganese — are among the most domestically abundant battery minerals in the United States:
- Iron: Mesabi Range, Minnesota — tens of millions of tonnes per year
- Manganese: Montana, Virginia, Minnesota deposits under active development
- Phosphate: Florida and North Carolina — major existing production
- Lithium: Nevada (Thacker Pass), North Carolina — significant domestic reserves
This contrasts sharply with NMC chemistries that require nickel (limited US deposits) and cobalt (70% DRC origin). BMLMP is the most achievable fully domestic chemistry in the advanced cathode landscape.
Applications
BMLMP is optimized for applications requiring the LFP safety profile with improved energy density: grid-scale BESS where cycle life and thermal stability are paramount, commercial fleet EVs where total cost of ownership matters more than maximum range, and defense applications requiring verifiable domestic supply chains alongside reliable performance.
