Crystal structure of Lithium Iron Phosphate
BenefitLithium Iron Phosphate in the nature
Triphylite: LiFePO4
(discharged condition)Heterosite: FePO4
(charged condition)
Lithium Iron Phosphate is a stable mineral since it exists in nature in both discharged and charged forms.
The oxygen and the phosphorus in the phosphate are strongly fixed by covalent bonds.
No release of oxygen when heated: temperature run-away reaction is not a concern for batteries based on Lithium Iron Phosphate

Long cycle life and deep discharge capabilities considerably improve the system’s Total Cost of Ownership and greatly reduce the environmental impact
Cell specifications Benefits
1 Sony LFP battery = 1,2 kWh (100% DoD, >8000 cycles)
is approximately equivalent to
2 kWh any other Li-Ion chemestry (60% DoD, <6000 cycles)
4 kWh Lead Acid battery (30% DoD, <3000 cycles)
No replacement needed for Sony LFP battery
Probably 1 replacement needed for other Li-Ion batteries
At least 2 replacements needed for Lead Acid batteries
