{"product_id":"cbccchdafr","title":"High Dyne Aluminum Foil Roll with High Adhesivity as Battery Cathode Current Collector, 1 kg or 3 kg\/roll, CBCCCHDAFR","description":"\u003cp\u003eHigh dyne aluminum foil is specifically engineered to have high surface tension, which is essential for ensuring that active material slurries adhere strongly to the current collector. When the dyne value of the foil is significantly higher than the surface tension of the coating slurry, the liquid \"wets out\" or spreads evenly rather than beading up. \"High Dyne\" foils often target 34–38 dynes\/cm, with some specialized etched foils reaching 66 dynes\/cm.
