Causes of california energy storage fires

What’s causing the fires? The lithium-ion batteries made with nickel manganese cobalt have high energy density, which makes them attractive for use in storage facilities. But in light of thermal runaway incidents, there’s been a movement toward lithium iron phosphate batteries that operate at lower temperatures and are less prone to fires. [pdf]

Can household coal storage cause spontaneous combustion

Spontaneous combustion has long been recognized as a fire hazard in stored coal. Spontaneous combustion fires usually begin as "hot spots" deep within the reserve of coal. The hot spots appear when coal absorbs oxygen from the air. Heat generated by the oxidation then initiated the fire. [pdf]
