Cobalt vs. Lithium: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 20, 2023
Cobalt is a hard, lustrous, silver-gray metal used in alloys and batteries, while lithium is a soft, silvery-white metal, crucial in batteries and psychiatric medication.

Key Differences

Cobalt, a transition metal, is known for its strength and high melting point, making it valuable in alloys. In contrast, lithium, an alkali metal, is the lightest metal and has a significantly lower melting point, used primarily in batteries and mental health treatment.
