preparation example Construction
[0016] The preparation method of the positive electrode of a primary battery provided by the present invention includes loading the positive electrode material on the current collector, the positive electrode material includes a positive electrode active material, a conductive agent and a binder, wherein the positive electrode active material is ferric oxide and / or Fe3O4.
[0017] The method of loading the positive electrode material on the current collector is well known to those skilled in the art. For example, the method of loading the positive electrode material on the current collector can be coating and / or filling the slurry containing the positive electrode material and solvent on the current collector, followed by drying and calendering, or it can be that the slurry containing the positive electrode The slurry of the material and the solvent is dried and pulverized to obtain a positive electrode material powder, and then the positive electrode material powder is roll...
Embodiment 1
[0026] This example illustrates the positive electrode provided by the present invention and the primary battery containing the positive electrode and their preparation methods.
[0027] (1) Preparation of positive electrode
[0028] 80 parts by weight of positive electrode active ingredient ferric oxide (SIGMA-ALDRICH), 4 parts by weight of binder polytetrafluoroethylene (number average molecular weight is 360,000), 4 parts by weight of conductive agent acetylene black are added to 52 grams of N-formazan In base pyrrolidone (NMP), then stir and mix to obtain positive electrode slurry.
[0029] The positive electrode slurry is dried at 150°C, and the dried material is ground into powder, and then the dried material powder is rolled into a sheet with a diameter of 13 mm with a tableting mold under a pressure of 2-4 MPa. A nickel mesh of 1.0 mm is used to make the positive electrode, and the amount of the positive electrode material is such that the content of the positive elec...
Embodiment 2
[0035] This example illustrates the positive electrode provided by the present invention and the primary battery containing the positive electrode and their preparation methods.
[0036] Prepare the battery according to the method of Example 1, the difference is that the positive electrode active material is 80 parts by weight of ferric oxide (Tianjin Kemiou Chemical Reagent Development Center), and the consumption of the positive electrode material is such that the nickel mesh per unit area, The content of the positive electrode material is 6 grams, which contains 0.1 gram of positive electrode active ingredient ferric oxide. An RC2016 lithium primary button battery A2 was prepared.
