{"product_id":"cfsge","title":"Gel Electrolyte (20mm * 20mm) for Flexible Supercapacitor, CFSGE","description":"\u003cp\u003eA gel electrolyte (often called a quasi-solid-state electrolyte) is a hybrid material that combines a liquid electrolyte with a solid polymer matrix. In supercapacitor R\u0026amp;D, these are the \"holy grail\" for flexible and wearable electronics because they offer the safety of a solid (no leakage) with the ion transport speeds of a liquid.\u003c\/p\u003e\n\u003cp\u003eThe polymer acts as a structural \"skeleton\" or host, while the liquid electrolyte is trapped within the polymer's pores. Ions migrate through the liquid-filled channels to the electrode surface, creating the electric double layer (EDLC) or facilitating Faradaic reactions (pseudocapacitance). (1) \u003cstrong\u003eStructure\u003c\/strong\u003e: Typically a 3D network formed by a polymer like PVA (Polyvinyl alcohol) or PEO (Polyethylene oxide). (2) \u003cstrong\u003eSafety\u003c\/strong\u003e: They solve the leakage, evaporation, and flammability issues common with traditional liquid electrolytes. (3) \u003cstrong\u003eFunction\u003c\/strong\u003e: Because they are flexible and can act as their own separator, they allow for thinner, \"all-in-one\" device designs.\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 236.275px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 41.175px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 41.175px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 41.175px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCFSGE (C-FS-GE)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.9px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 22.9px;\"\u003e\u003cem\u003eGel Electrolyte Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 22.9px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eL 20 mm * W 20 mm * T 2mm (thinner thickness of 1 mm can be supplied upon request)\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.3848%; height: 35.6px;\"\u003e\u003cem\u003eGel Electrolyte Types\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.2197%; height: 35.6px;\"\u003e\n\u003cp\u003e(1) Poly(acrylic acid) (PAA) Gel Electrolyte\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: It is mainly used for high alkaline electrolyte (eg: KOH, NaOH) and neutral electrolyte (eg: NaCl, KCl, Na2SO4) under low concentration (\u0026lt;0.2 M).Please don't apply it to acidic electrolyte and high ion concentration (\u0026gt;0.5M)\u003c\/p\u003e\n\u003cp\u003e(2) Polyacrylamide (PAM) Gel Electrolyte\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: It is mainly used for zinc-based electrolyte (eg: ZnCl2, ZnSO4) and acidic H2SO4 electrolyte (eg: NaCl, KCl, Na2SO4) under high concentration (\u0026gt;3.0 M).
