Thermal runaways and field-failures can occur in ALL lithium battery chemistries. In recent years, a myth has been propagated by certain industry participants and battery scientists that the lithium iron phosphate chemistry is effectively ‘immune’ to catastrophic thermal runaway events. When one examines the available facts, it is obvious that this myth or widely-held belief is simply not true --- it is a fool’s paradise. Importantly, reasonably well-documented thermal runaways have been reported that involved LiFePO4 battery cells and multi-cell arrays. For example, a May 2013 incident at California Polytechnic State Univ. resulted in a thermal runaway fire and quasi-explosion that completely melted the battery’s contents and case. Two other likely examples of runaways with LiFePO4 batteries are noted in this document.
Conclusion: albeit more rare, LiFePO4 lithium-based batteries can in fact also experience catastrophic thermal runaway events, even including explosions/detonations; from a product safety perspective they should be viewed with same prudent circumspection and caution as other types of lithium-based batteries such as lithium-cobalt, lithium-manganese, and lithium-ion chemistries.
LENRs effectively create nano energetic materials in micron-scale regions on surfaces, aromatic rings, and at certain types of interfaces.
