Abstract The increasing demand for alkali metal‐ion batteries necessitates efficient and sustainable recycling solutions both end‐of‐life production scrap. This study introduces a novel, cost‐effective, scalable electrode delamination technique, termed “ice‐stripping,” which employs sub‐zero freezing to achieve near‐complete (>90%) recovery of coatings. Water is sprayed onto the surface placed on surface; water freezes, forming strong interfacial bond coating cold plate. enables current collector be stripped away from due stronger adhesion Unlike conventional thermal or chemical methods, ice‐stripping minimizes energy consumption, eliminates hazardous chemicals, preserves morphology integrity reclaimed materials. technique successfully applied scrap lithium‐ion sodium‐ion battery electrodes with various binder systems. Case studies focus efficiencies potential direct Prussian white hard carbon electrodes, graphite cells, cathode anode manufacturing Scalability integration are also discussed. Given its efficiency sustainability, represents transformative step forward in technology, reducing environmental impact promoting material circularity.
