▎ 摘　　要

NOVELTY - Conductive agent comprises conductive carbon black (100), first carbon nanotubes, second carbon nanotubes and graphene at mass ratio of (0.1-1.0):(0.2-0.8):(0.1-1.2):(0.1-0.5). The tube length of first carbon nanotube is 10-90 mum. The second tube length of carbon nanotubes is 5-50 mum. The tube length of first carbon nanotubes is greater than tube length of second carbon nanotubes. USE - Conductive agent used for electrode slurry (claimed). ADVANTAGE - The conductive agent improves conductivity, multiplying power performance and low temperature performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. an electrode paste, which comprises electrode material, binder and conductive agent; 2. an electrode sheet, which comprises current collector and electrode material layer set on current collector, electrode material layer comprising electrode slurry coating formed by material; and 3. a battery, which comprises electrode sheet. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of conductive agent. Conductive carbon black (100) Electrode material particles (200)
