Abstract

High-performance conductive composites are essential for applications in renewable energy, high-voltage power transmission, flexible printed electronics, and brain-computer interfaces, where both high electrical conductivity and excellent mechanical strength are required. Using a novel centrifugal atomization technique and specialized equipment, the authors successfully produced highly reactive micrometer-scale pure calcium metal powder and developed a lightweight, high-strength, and highly conductive aluminum-based pure calcium composite. Compared with conventional industrial aluminum cable materials, the composite offers a 28% reduction in density, a 58% increase in strength, a 28% improvement in electrical conductivity, and a 22% reduction in power transmission losses, enhancing both the reliability of conductive cable materials and the energy efficiency of high-voltage power transmission. The authors also developed a novel metal–2D hybrid conductivity-enhancing additive that improves the electrical conductivity of conductive pastes by 41.5% compared with conventional silver conductive paste under the same printing and sintering conditions, increases the conductivity of sintered silver powder compacts by 17%, and enhances the conductivity of EEG conductive pastes by 80%. These innovations demonstrate significant potential for a wide range of advanced conductive material applications.
