▎ 摘 要
NOVELTY - Carbon current collector comprises a carbon material film and conductive fibers, where the conductive fibers are distributed in the carbon material film along the length direction of the carbon current collector. USE - The carbon current collector is used in electrochemical device and electronic device i.e. lithium ion battery, and solar cell. ADVANTAGE - The carbon current collector: has higher tensile strength, lower internal resistance, and better quality property and processing application feasibility; lithium ion battery using the current collector can have higher energy density and better multiplying power performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing carbon current collector; electrochemical device; and electronic device.
