A lithium manganese iron phosphate (LMFP) battery is a lithium-iron phosphate battery (LFP) that includes manganese as a cathode component. As of 2023, multiple companies are readying LMFP batteries for commercial use. [1] Vendors claim that LMFP batteries can be competitive in cost with LFP, while achieving superior performance. [2]
For example, an NMC molar composition of 33% nickel, 33% manganese, and 33% cobalt would abbreviate to NMC111 (also NMC333 or NCM333) and have a chemical formula of LiNi 0.33 Mn 0.33 Co 0.33 O 2. A composition of 50% nickel, 30% manganese, and 20% cobalt would be called NMC532 (or NCM523) and have the formula LiNi 0.5 Mn 0.3 Co 0.2 O 2.
In Europe, the MMT DNELs (Derived No Effect Level) for workers by the inhalation and dermal routes of exposure are 0.6 mg/m 3 and 0.11 mg/kg-day, respectively. The MMT DNELs for the general population by the inhalation and dermal routes of exposure are 0.11 mg/m 3 and 0.062 mg/kg-day, respectively.
The Mn(II) formed is soluble in most electrolytes and its dissolution degrades the cathode. With this in mind many manganese cathodes are substituted or doped to keep the average manganese oxidation state above +3.5 during battery use or they will suffer from lower overall capacities as a function of cycle life and temperature.

The battery requires from 0.15 to 0.3 kg (5 to 10 oz) of lithium per kWh. As designed these primary systems use a charged cathode, that being an electro-active material with crystallographic vacancies that are filled gradually during discharge.

Manganese is a chemical element with the symbol Mn and atomic number of 25. It is found as the free element in nature (often in combination with iron), and in many minerals. The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as
