Sodium
A soft, silvery-white, and highly reactive alkali metal that is never found free in nature.
Overview
Sodium is increasingly significant in the automotive sector as the core component of sodium-ion batteries, which offer a sustainable and lower-cost alternative to lithium-ion systems. It is also utilized in hollow-stem engine valves as a liquid cooling medium due to its high thermal conductivity, effectively transferring heat away from the valve head. Due to its extreme reactivity with water and oxygen, it must be handled in inert environments or stored under oil. In the supply chain, sodium is prized for its extreme crustal abundance and geographical diversity compared to critical minerals like lithium.
