Could Aluminum Outperform Copper in Electrical Applications?

Chapter 1: The Rise of Aluminum
In a recent study conducted by the Pacific Northwest National Laboratory (PNNL), new insights into the conduction properties of metals have emerged, suggesting a path towards enhancing aluminum's conductivity.
Copper reigns supreme in the world of electrical circuits. It's the go-to material for everything from portable gadgets to the underwater cables that sustain our internet connections. In the United States, copper wires are the backbone of power transmission.
However, the availability of copper is declining while its demand continues to rise, leading to increased costs. In contrast, aluminum is approximately 1000 times more abundant than copper. Moreover, it is one-third the weight and cost of copper.
Despite these advantages, aluminum's conductivity is only about 60% that of copper. Yet, the potential benefits of substituting copper with aluminum are compelling, especially in electric vehicles (EVs), where copper coils add unnecessary weight, slowing down performance. Utilizing aluminum wiring could reduce vehicle mass, potentially extending battery life.
If researchers can enhance aluminum's conductivity to at least 80 to 90% of copper's, we might see a widespread transition from copper to aluminum in various applications. However, the challenge lies in the fact that increasing a metal's conductivity is largely uncharted territory, although it is a common practice in the realm of semiconductors and insulators.
Fortunately, the team at PNNL has taken significant steps in this direction by employing Density Functional Theory to model the conductivity of metals for the first time. Their findings appear to align closely with real-world observations.
By introducing phonons or various lattice defects, scientists may have discovered a method to manipulate aluminum's conductivity, potentially paving the way for an aluminum-centric future.
