DETAILED DESCRIPTION - Preparing positive electrode conductive agent involves pressing graphite particles into graphite flakes (4). The graphite sheet is utilized as a working electrode, and the graphite sheet. The diaphragm (6) and the counter electrode are attached and placed in an electrolyte. The diaphragm is located in the graphite sheet and the counter electrode. A forward constant current and a reverse constant current are repeatedly applied in the graphite sheet and the counter electrode. The ions in the electrolyte are repeatedly inserted and extracted in the graphite layers of the graphite sheet. The graphite flakes undergone multiple oxidation and reduction. The flakes are compared with the previous oxidation of the graphite sheet when the duration of oxidation decreases. The oxidation of the graphite sheet is stopped. The graphene agglomerate is obtained after the graphite sheet is reduced once again. The graphene agglomerates and the dispersing agent are dissolved in a solvent, stirred and dispersed to obtain a graphene slurry followed by utilizing the graphene slurry to form a positive electrode conductive agent. INDEPENDENT CLAIMS are included for: (1) a positive electrode sheet, which comprises a positive electrode current collector and a positive electrode additional layer arranged on one side surface of the positive electrode current collector, where the positive electrode additional layer is an integrated mixed layer, and the positive electrode additional layer comprises positive electrode active material, a positive electrode binder, and the positive electrode conductive agent; and (2) a battery, which comprises a negative pole piece, a separator and the positive pole piece, where the separator is located in the negative pole piece and the positive pole in slices.
