Collector for electrode of electricity storage device i.e. lithium-ion battery, has carbon nanotubes aligned by forming angle equal to specific degrees with respect to substrate, and aluminum thin layer formed on substrate

摘要

The collector (11) has carbon nanotubes (14) aligned by forming an angle (alpha) equal to 90 degrees with respect to a substrate (13). An aluminum thin layer (15) is formed on the substrate. The nanotubes are arranged so as to provide a network such as a connection between volume occupied by the nanotubes and volume defined by the collector lies between 1 percent and 10 percent, where each nanotube is provided with a cylinder or multiple concentric cylinders with external diameter ranging between 1 and 100 nm and inner diameter less than 10 nm. An independent claim is also included for a method for manufacturing a collector.
