Combined with a BMS, Lithium Iron Phosphate (LifePO4 – LFP) is
currently the most secure Lithium-Ion technology on the market.
Lithium-Ion refers to a family of Lithium-based battery technology.
This family includes several sub-families or technologies, such as:
LCO: Lithium Cobalt Oxide
NCA: Nickel Cobalt Aluminium
NMC: Nickel Manganese Cobalt
LiFePO4 or LFP: Lithium Iron Phosphate
LTO: Lithium Titanate Oxide, etc…
The nail penetration test is the most revealing way to qualify the safety of a cell
We find under the same extremely stable behavior of Lithium Iron
Phosphate cells while the NMC cell ignites almost immediately.
One of the main causes of danger for lithium-ion cells is related
to the phenomenon of thermal runaway. This is a heating reaction of the battery in use, caused by the
nature of the materials used in the chemistry of the battery.
Thermal runaway is mainly caused by the solicitation of batteries
under specific conditions, such as overload under adverse climatic
conditions. The result of a thermal runaway of a cell depends on
its level of charge and can lead in the worst case to an
inflammation or even an explosion of the Lithium-Ion cell.
However, not all types of Lithium-Ion technology, due to their
chemical composition, have the same sensitivity to this phenomenon.
The figure below shows the energy produced during an artificially
induced thermal runaway
It can be seen that among the Lithium Ion technologies mentioned
above, LCO and NCA are the most dangerous chemicals from a thermal
runaway point of view with a temperature rise of about 470°C per
minute. The NMC chemistry emits about half the energy, with an increase of
200°C per minute, but this level of energy causes in all cases the
internal combustion of materials and the ignition of the cell.
In addition, it can be seen that LiFePO4 – LFP technology is is
slightly subject to thermal runaway phenomena, with a temperature
rise of barely 1.5°C per minute.
With this very low level of energy released, the thermal runaway of
the Lithium Iron Phosphate technology is intrinsically impossible
in normal operation, and even almost impossible to artificially
