Abstract

Systems and methods are disclosed for recovering lithium inventory and extending the operational life of lithium manganese iron phosphate (LMFP) batteries exhibiting multiphase electrochemical behavior. In example implementations, a battery cell configured with LMFP cathode materials having phase-dependent lithium transport characteristics undergoes a controlled recovery operation initiated in response to aging indicators. The recovery operation includes regulating the battery cell to a defined elevated temperature range for at least one phase of a multiphase reaction and directing a charging process while the cell is within the temperature range to promote lithium-ion migration from less accessible regions to active electrochemical sites. In some implementations, the charging process includes a low-rate charge followed by a normal-rate discharge. The disclosed techniques may be implemented by a battery management system and are applicable to vehicle, industrial, and stationary energy storage systems to improve capacity retention, operational stability, and lifecycle performance of aged LMFP batteries.
