CAS:124-68-5|Application of AMP in lithium batteries

2023-05-16 来源:转载自第三方

Lithium ion batteries are widely used in aerospace, military, and electric vehicles due to their high energy density, high output voltage, superior cycling performance, and green environmental protection. In the production process of lithium-ion batteries, the positive electrode usually uses polyvinylidene fluoride as the binder, the solvent is N-methylpyrrolidone, and the negative electrode uses a non-aqueous organic solvent as the electrolyte. Due to the problems of low conductivity, poor processing performance, and easy dropout during coating and cycling of existing lithium-ion battery cathode materials. A positive electrode conductive agent for lithium-ion batteries with good conductivity, adhesion, and solvent resistance has been developed in the CN104538638B patent. This week, YACOO editor will briefly introduce the positive electrode aluminum foil conductive agent for lithium-ion batteries.
      Lithium ion battery positive electrode aluminum foil conductive agent is prepared from the following raw materials (calculated by weight percentage):
      Graphite 15.0-22.0%, conductive carbon black 3.0-6.0%, modified waterborne epoxy resin 5.0-10.0%, butadiene styrene polymer 11.0-25.0%, sodium carboxymethyl cellulose 0.1-1.5%, sodium polyacrylate 0.05-0.5%, peach gum 2.0-6.5%, 2-amino-2-methyl-1-propanol (CAS: 124-68-5) 0.3-0.8%, polyoxyethylene dehydrated sorbitol monolaurate 0.05-0.5%, polyvinylpyrrolidone 0.2-0.7%, sodium methylene naphthalenesulfonate 0.3-1.0%, Ammonia water is 2.0-6.0%, and the rest is deionized water.
     In this patent, the main function of 2-amino-2-methyl-1-propanol is as a pH stabilizer.
     2-Amino-2-methyl-1-propanol (AMP, CAS 124-68-5) is an organic compound with the molecular formula C6H15NO5S and a molecular weight of 89.14. AMP can be used as a vulcanization accelerator, acidic gas absorber, and additive for coatings, with pigment dispersion, pH adjustment, and rust prevention effects. YACOO can provide customers with high-quality services of AMP from gram to ton.
