LFP
LFP (lithium iron phosphate) is the main cell chemistry in stationary storage: cobalt- and nickel-free, more thermally stable and longer-lived than NMC.
What does LFP mean?
Lithium iron phosphate (LiFePO4) is today’s dominant cell chemistry for stationary storage. Compared with nickel-based chemistries (NMC/NCA), it contains no cobalt or nickel, offers higher thermal stability and tolerates far more cycles — paid for with somewhat lower energy density.
For stationary applications that trade is almost always right: weight and volume are secondary at a commercial site, safety and cycle life primary. The entire Speichercampus portfolio uses LFP.
What matters in practice
- thermal stability does not replace a fire-protection concept — it eases it
- LFP likes shallow cycles and moderate temperatures: good for the design
- the flat voltage curve makes SOC measurement more demanding (BMS quality!)
- cell format and manufacturer matter for warranty and spare parts
Practical example
An insurer asks about cell chemistry for the commercial policy. The statement “LFP with aerosol suppression, UL9540A-tested” shortens the assessment considerably — the chemistry choice reaches all the way into the premium.
The Speichercampus perspective
Speichercampus deliberately carries LFP systems exclusively — from the 100 kWh class to the 6.25 MWh container.
