{"product_id":"ceeeapss","title":"PSS (Polystyrene Sulfonate) as Electrode Binder and Electrolyte Additive, 25 g\/bottle, CEEEAPSS","description":"\u003cp\u003eIn electrochemistry, Polystyrene Sulfonate (PSS)—most commonly used as its sodium salt, Poly(sodium 4-styrenesulfonate)—is a versatile anionic polyelectrolyte. Its primary function is providing a high density of fixed negative sulfonic acid groups (-SO3^-), which allows it to conduct cations while remaining structurally stable.\u003c\/p\u003e\n\u003cp\u003ePSS is often used as a \u003cstrong\u003ewater-soluble binder\u003c\/strong\u003e for carbon-based electrodes. Unlike traditional PVDF binders, PSS is ionically conductive. This reduces the internal resistance of the electrode by facilitating faster cation (Li+, Na+, or K+) transport through the binder network to the active material. It improves the rate capability (fast charging) of the battery and is more environmentally friendly than solvent-based binders.\u003c\/p\u003e\n\u003cp\u003ePSS is increasingly used to modify the environment around CO2 reduction catalysts. (1) \u003cstrong\u003eLocal pH Management\u003c\/strong\u003e: PSS can be used as an ionomer in catalyst inks to provide a high concentration of fixed negative charges. This helps repel carbonate ions (CO3^{2-}) and manage the local proton concentration. (2) \u003cstrong\u003eHydrophilicity\u003c\/strong\u003e: Its highly hydrophilic nature ensures that the catalyst layer is well-wetted in aqueous systems, maintaining a high active surface area for the reaction.\u003c\/p\u003e\n\u003cp\u003eIn zinc or copper \u003cstrong\u003eelectroplating\u003c\/strong\u003e, PSS is added to the bath as a \"\u003cstrong\u003eleveling agent\u003c\/strong\u003e.\" PSS adsorbs onto the high-energy \"peaks\" of the growing metal surface, creating a local resistive barrier. This forces the metal ions to deposit in the \"valleys,\" resulting in a smooth, mirror-like finish and preventing the growth of dendrites that cause short circuits.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 443.738px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6875px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 47.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 47.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCEEEAPSS (C-EEEA-PSS)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 46.4125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 46.4125px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 46.4125px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cbr\u003e9080-79-9\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 46.4125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 46.4125px;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 46.4125px;\"\u003e\n\u003cp\u003e (C8H7NaO3S)n\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CEEEAPSS_molecular_structure_160x160.png?v=1771962008\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 46.4125px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 46.4125px;\"\u003e\u003cem\u003eAppearance\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 46.4125px;\"\u003e\n\u003cp\u003e\u003cspan\u003eWhite powder \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 10px;\"\u003e\u003cem\u003eMolar Mass\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 10px;\"\u003e\n\u003cp\u003eMw ~10600\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.0375px;\"\u003e\n\u003ctd style=\"width: 28.0576%; height: 26.0375px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.5827%; height: 26.0375px;\"\u003e25 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the PSS powder in a dry place. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/link.springer.com\/article\/10.1007\/s10800-020-01497-y\"\u003eF.
