In short
LFP (LiFePO4) is a type of lithium-ion cell with a lithium iron phosphate cathode. NMC is the type whose cathode contains nickel, manganese and cobalt.
What is an LFP home battery?
LFP stands for lithium iron phosphate (LiFePO4). Most home batteries are lithium batteries, usually of the LFP type. NIPV describes that lithium-ion batteries mainly use nickel, manganese and cobalt in the cathode, that manufacturers want to use less of them and that LFP is therefore used more and more. All plug-and-play batteries in the Voltravo shop are LFP.
That does not tell you everything about a model. Power, warranty, placement and connection differ per product, see what is a home battery.
LFP and NMC side by side
The table compares LFP and NMC qualitatively, without figures. Figures on lifespan are in the datasheet of the model itself.
How long a battery lasts differs per model. Compare the stated cycles and the manufacturer's warranty per model (see below). One drawback of LFP is its lower energy density compared to NMC: for the same capacity the battery weighs more.
| Property | LFP (lithium iron phosphate) | NMC (nickel manganese cobalt) |
|---|---|---|
| Cathode | Iron and phosphate | Nickel, manganese and cobalt |
| Energy per kilogram | Lower: heavier per kWh | Higher: lighter per kWh |
| Use in home batteries | Most common | Less common |
| Lifespan | Differs per model: check the cycles and warranty in the datasheet | Same |
Is an LFP home battery safer?
LFP is often seen as a more stable cell chemistry than NMC. NIPV writes that thermal runaway can occur in all current lithium-ion subtypes, and that its likelihood and effect are somewhat lower for LFP than for NMC. Still, do not assume an LFP battery carries no risk.
The Netherlands Institute for Public Safety also writes that thermal runaway, an uncontrolled chain reaction in the battery, is hard to predict and that home fires involving a home battery can develop faster and more intensely than ordinary home fires. That research covers lithium-ion home batteries in general and does not mention LFP or NMC. Placement, connection and maintenance therefore matter just as much. Choose the location with care: well ventilated, away from walkways and escape routes and with a smoke and carbon monoxide detector. Also ask the supplier about the safety certification of the battery, for example the IEC-EN 62619 standard in the datasheet. What the fire service advises on placement, connection and maintenance is in placing and maintaining a home battery fire-safely.
Cycles and warranty per model
Cycles and warranty per model are in home battery lifespan: cycles, warranty and wear. The specifications per product are on the product pages in the shop. In the datasheet of a model, look at the number of cycles, the remaining capacity that goes with it and the manufacturer's warranty, and compare models on the same basis.
Where LFP does less well
At cell level LFP stores less energy per kilogram than NMC. Weight according to the product specification: the Marstek Venus E 3.0 weighs 60 kg for 5.12 kWh, the TSUN PowerTrunk 52 kg for 5.12 kWh and the AEG Solarcube 54 kg for 6.028 kWh. Check in the manual how and where to carry that weight. For more on choosing model, power and capacity, see calculating home battery capacity, and for use next to panels home battery with solar panels.
LFP is not automatically environmentally friendly either: Milieu Centraal writes that it takes a lot of energy to mine and process the raw materials for batteries, and that the environmental impact differs per type of battery.
