    摘要： The present invention provides carbon nanotubes which satisfy 3 ≤ Z ≤ 80, where Z (nm) is the pore size at the peak top in the pore size distribution of the carbon nanotubes having a diameter of 2 nm or more and 200 nm or less as determined by a BJH method, while satisfying the requirement (A) or (B) described below. (A) In the pore size distribution, the integral value of the pore volume of carbon nanotubes having a diameter of 10 nm or more and 80 nm or less is 50% or more relative to the integral value of the pore volume of carbon nanotubes having a diameter of 2 nm or more and 200 nm or less; and the pore volume is 1.10 to 2.20 cm 3 /g. (B) In the pore size distribution, the integral value of the pore volume of carbon nanotubes having a diameter of 3 nm to 20 nm is 50% or more relative to the integral value of the pore volume of carbon nanotubes having a diameter of 2 nm or more and 200 nm or less; and the pore volume is 0.80 to 1.90 cm 3 /g.

    摘要： This application proposes an electrode, an electrochemical apparatus, and an electronic apparatus. The electrode includes a current collector and an active material layer located on one side or two sides of the current collector, the active material layer including an active material and a conductive agent. The conductive agent includes carbon nanotubes, the active material layer includes rope-shaped carbon nanotube aggregates formed by the carbon nanotubes, the carbon nanotube aggregates are interwoven to form a cage-like network, and the active material is wrapped inside the cage-like network. The carbon nanotube aggregates are used to wrap particles of the active material, thereby enhancing the long-range conductivity of the active material layer and improving the structural stability.
