Abstract

Disclosed are lithium manganese iron phosphate (LMFP) battery systems, cells, and methods configured to smooth stair-like voltage behavior inherent to LMFP chemistries. The disclosure describes blending LMFP cathode materials having different iron-to-manganese ratios to moderate multiphase redox reactions and produce a more slope-like voltage profile during charge and discharge. The blended cathode materials may be integrated at a material level, electrode level, cell level, or pack level to improve state-of-charge estimation, power control, and battery management system performance while preserving the inherent safety, cost, and cycle-life advantages of LMFP chemistry. The disclosed systems support modular battery architectures and are adaptable to electric vehicles, heavy-duty applications, and stationary energy storage. By reducing steep voltage transitions without introducing higher-risk chemistries, the disclosed approaches enable improved controllability, reliability, and scalability of LMFP-based energy storage systems.
