What are the benefits of Lithium-Iron-Phosphate (LiFePO4) chemistry for temperature stability compared to other Li-family battery chemistries (LiCoO2, LiMn, etc.)?
Unlike the other Li-family cells, LiFePO4 does not have problems with thermal runaway under normal operating conditions that other Li-family batteries have exhibited in the past. The maximum measured temperature radiated from the cells during normal operation is 55’C. LiFeBATT cells can handle over 160’C without any loss of total capacity. At 180’C or ~450’F the cells release Lithium gases that are non-toxic in small doses. However, this worst case scenario would only occur under extreme conditions, say a major fire in an electrical system. As a safety design, pressure valves inside the individual cells would keep the cells from exploding. The internal Voltage Monitoring System (VMS) and casing construction would protect the cells from electrical and physical damage.
