摘要： Provided herein is a method of making a conductive network by combining uncoated carbon nanotubes and carbon nanotubes coated with an electroactive substance to create an electrically conductive network; and redistributing at least a portion of the electroactive substance. Also provided herein is an electrically conductive network with an active material coating; first carbon nanotubes coated with the active material coating; and second carbon nanotubes partially coated with the active material coating, wherein at least a portion of the surfaces of the second carbon nanotubes directly contact surfaces of other second carbon nanotubes without the active material coating between these second carbon nanotubes, and wherein the first carbon nanotubes and the second carbon nanotubes are entangled to form an electrically conductive network.

摘要： Provided herein is a method of manufacturing a nanoscale coated network, which includes providing nanofibers, capable of forming a network in the presence of a liquid vehicle and providing a nanoscale solid substance in the presence of the liquid vehicle. The method may also include forming a network of the nanofibers and the nanoscale solid substance and redistributing at least a portion of the nanoscale solid substance within the network to produce a network of nanofibers coated with the nanoscale solid substance. Also provided herein is a nanoscale coated network with an active material coating that is redistributed to cover and electrochemically isolate the network from materials outside the network.
