Can a LiFePO4 battery set itself on fire? In some very rare cases any battery can set itself on fire. There are examples of situations when a battery (in a mobile phone) set itself on fire. This may happen perhaps once in 10 000 units, once in a period of 5 years. Will you stop using mobile phones because of this danger? In fact: the LiFePO4 technology is much more stable and much safer than the Li-poly cells used in mobile phones, tablets and notebooks. While the Li-poly cells may actually explode and burn completely very fast (nearly instantly), the LiFePO4 cells usually remain complete and only the plastic case or internal material may burn slowly (for many minutes). During the last 6 years of our battery business at GWL, we have sold over 15 000 000 Ah of cell capacity: this corresponds to some 300 000 pieces of individual cells. From this quanity we have recored only less than 10 cases of battery related fire. In fact from these less than 10 cases, most were related to electric short curcuit (user failure), not to a battery (cell) failure. Others were caused by over charging. This proves the LiFePO4 technology is extremely safe and reliable. Will you stop using mobile phones because of lithium cells? Will you stop using LiFePO4? | |
