Simplifying electrode design for lithium-ion rechargeable cells

In the race to improve lithium-ion cell manufacturing, societal impact is a chief concern as significant resources are required to meet increasing demands. Modified cell designs which employ foils and textiles may offer a scalable path to realizing sustainability. Here we demonstrate one possibility for a simplified lithium-ion energy storage device that utilizes a pre-lithiated aluminum foil anode and a carbon fiber cathode, potentially avoiding energy and cost-intensive production steps.
