▎ 摘 要
NOVELTY - The electrode pole sheet has a current collector and an electrode mixture arranged on the side surface of the current collector. The electrode mixture includes 90-97 %mass active materials, 0.01-2 %mass, preferably 0.3-0.8 %mass polyacrylonitrile and 0.01-2 %mass, preferably 1.2-1.8 %mass nano-ceramic materials based on the mass of the electrode mixture as 100 %mass. The nano-ceramic material includes nano-alumina, boehmite or zirconia. The electrode mixture includes a 2-4 %mass conductive agent and a 3-5 %mass binder. The conductive agent includes conductive carbon black, conductive graphite, carbon fiber, carbon nanotubes or graphene. The binder includes polytetrafluoroethylene, polyvinylidene fluoride or styrene-butadiene rubber. USE - Electrode pole sheet for battery (claimed) such as lithium-ion batteries used in electric vehicles and energy storage fields. ADVANTAGE - The electrode pole sheet material has higher ion conductivity under the same compaction density by adding polyacrylonitrile (PAN) and nano-scale ceramic particles to the electrode pole sheet, and further improves the pole sheet compaction density under the condition of ensuring battery performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing electrode pole sheets, which involves miixing polyacrylonitrile, binding agent, nano-ceramic material and solvent to obtain glue, mixing active material and conductive agent with the glue to obtain electrode slurry, and coating the electrode slurry on the surface of the current collector, rolling and drying to obtain the electrode sheet; and (2) a battery.
