Abstract:

In today's rapidly evolving technological landscape, silicon may dominate the conversation, but the true story of modern technology is far more complex. Behind every smartphone, electric vehicle, and renewable energy system lies a network of critical elements—lithium, cobalt, rare earth elements, and more—that are just as essential as silicon in driving innovation. These materials form the backbone of modern devices, but their extraction, availability, and environmental impacts present significant challenges. This article delves into the critical roles these elements play, examining their unique properties, applications, and the geopolitical and ethical considerations surrounding their acquisition. Through a detailed exploration of current research and case studies, we uncover the often-overlooked building blocks of the digital age and highlight pathways toward sustainable sourcing and recycling.
