LFP
LFP in the Speichercampus context: a robust cell chemistry for stationary storage. Technically, the term is usually described as lithium iron phosphate.
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.
