All figures are typical ranges, not a substitute for a specific cell datasheet — they vary by manufacturer, cell format and C-rate.
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.
Engineering interpretation, not a purchasing guarantee.
Evidence card — how this chemistry’s data was established
Basis: typical ranges cross-verified from cell-manufacturer datasheets and 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.
