Lithium Iron Phosphate (LFP)
A lithium battery chemistry (LiFePO4) known for safety, longevity, and thermal stability. Used in most residential battery systems. Lower energy density than NMC but 5,000-10,000 cycle rating.
Why It Matters
LFP batteries last 2-3x longer than NMC and do not present a thermal runaway fire risk. Most major home battery brands (Tesla, Enphase, Fortress) now use LFP.

LFP (Lithium Iron Phosphate)
A lithium-ion battery chemistry (LiFePO₄) known for long cycle life (4,000-10,000 cycles), high safety (no thermal runaway), and lower energy density compared to NMC.
NMC Battery (Nickel Manganese Cobalt)
A lithium-ion battery chemistry (LiNiMnCoO₂) with higher energy density than LFP but shorter cycle life (1,500-3,000 cycles) and higher thermal runaway risk.
Thermal Runaway
An uncontrolled self-heating chain reaction in a battery that can lead to fire or explosion if the internal temperature exceeds a critical threshold.
Cycle Life
The number of complete charge-discharge cycles a battery can perform before its capacity drops below a specified threshold (typically 70-80% of original capacity).
