![]() ![]() When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. They can also withstand harsh conditions, be it freezing cold, scorching heat or rough terrain. Lithium phosphate cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. Overall, the iron phosphate-oxide bond is stronger than the cobalt-oxide bond, so when the battery is overcharged or subject to physical damage then the phosphate-oxide bond remains structurally stable whereas in other lithium chemistries the bonds begin breaking down and releasing excessive heat, which eventually leads to thermal Runaway. ![]() This is because the charged and uncharged states of LiFePO4 are physically similar and highly robust, which lets the ions remain stable during the oxygen flux that happens alongside charge cycles or possible malfunctions. Thus, providing an increase in safety over lithium-ion batteries made with other cathode materials. Phosphate-based batteries offer superior chemical and mechanical structure that does not overheat to unsafe levels. ![]()
