A novel class of resource-efficient, woven-glass-grid current collectors (CCs) for Li-ion batteries is introduced. These CCs are based on ultra-light multifilament glass threads, woven to a grid and surrounded with a thin metal layer (equivalent to a 1 μm-thick metal foil) in a roll-to-roll physical vapor deposition process. This saves >
90 % of the required Cu and Al metals and reduces the mass of the CCs by >
80 %. At the same time, the gravimetric capacity of anodes with graphite and cathodes with LiCoO
