Addressing the grand challenges in electrochemical energy systems is often motivated by improving sustainability conversion and storage. However, design of materials, components for storage devices, particular batteries, prioritizes performance cost. Sustainability comes third, as, historically, a focus on advancements has incurred penalties terms and/ or cost most conventional products. This interplay will certainly evolve coming years. Ecological social aspects driven legislative...
