Resource-Efficient Electrodes with Metallized Woven-Glass-Grid Current Collectors for Lithium-Ion Batteries.

ABSTRACT: 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 LiCoO₂ active material increases by 48 % and 14 %, respectively, while full cells are characterized by an increase of 26 %. Thus, the specific energy can be improved by 25 %. A complete anode and cathode fabrication process from preparing the CCs and electrodes to cells is described a
