LMFP Battery Chemistry

Lithium manganese iron phosphate

At a glance: LMFP is Lithium manganese iron phosphate — a lithium cell chemistry with a nominal voltage of 3.5–3.6 V, cell-level energy density around 150–200 Wh/kg, typical cycle life of 2,000–4,000 cycles, and a temperature window of discharge −20 to +55 °C · charge 0 to +45 °C.

All figures are typical ranges, not a substitute for a specific cell datasheet — they vary by manufacturer, cell format and C-rate.

Engineering interpretation

What the data means: LMFP’s position in the chemistry family is set by two numbers working against each other — energy density (Wh/kg) and cycle life. LMFP sits at roughly 150–200 Wh/kg and 2,000–4,000 cycles, which places it at a specific point on the energy-versus-longevity trade-off.

Why it matters: A datasheet number only means something with its basis — cell-level energy density is not pack-level, and cycle life is only meaningful at a stated depth of discharge and temperature. Read LMFP against those conditions, never as a bare figure.

Sources & verification

Evidence card — how this chemistry’s data was established

Basis: typical ranges cross-verified from cell-manufacturer datasheets and battery engineering references.

Cell-manufacturer datasheets (Gotion, CATL — early LMFP lines)
Battery engineering references

Emerging chemistry with a wider vendor spread — treat energy-density and cycle-life figures as indicative rather than settled. Higher manganese content raises nominal voltage and energy density versus LFP.

Frequently asked questions

What is LMFP?

Lithium manganese iron phosphate. Nominal voltage 3.5–3.6 V, energy density 150–200 Wh/kg (cell level (vendor-dependent)), typical cycle life 2,000–4,000 cycles.

What is the cycle life of LMFP?

2,000–4,000 cycles. The basis is: cycles to 80% capacity, ~80% DOD, 25 °C.

Is LMFP suitable for my application?

It depends on the duty cycle. LMFP has an energy density of 150–200 Wh/kg and a temperature window of discharge −20 to +55 °C · charge 0 to +45 °C. Compare that with the application's energy, power, cycle-life and temperature requirements before choosing.
