Researchers at Germany’s Federal Institute for Materials Research and Testing have published a perspective paper calling for a shift in how high-performance materials are developed. The authors argue that materials used in batteries, hydrogen technologies, wind turbines, energy systems, chemical processes and electronics should be designed from the beginning for long-term stability, reusability and reduced reliance on scarce resources.
Many advanced materials currently depend on rare or geopolitically sensitive elements. These substances often degrade quickly in real-world conditions and prove difficult to recycle, leading to higher costs and supply vulnerabilities. The researchers propose moving beyond a sole focus on peak performance to also prioritize durability and resource availability during the design phase.
Three main strategies are outlined: replacing critical elements with more abundant alternatives, deliberately engineering material defects to enhance stability, and combining diverse chemical components to improve robustness and versatility. The approach is seen as especially relevant for the energy transition, where components must withstand prolonged stress while supporting recycling efforts.
Early examples include battery materials that reduce cobalt use, proton-conducting substances effective at higher temperatures in fuel cells, and multicomponent alloys that match platinum’s catalytic performance. The authors stress that successful technologies must operate reliably over years rather than only under laboratory conditions.
