Carbon nanotubes with a diameter of 8-10nm and a length of 10-15μm, POE and other excipients are mixed through an internal mixer and then granulated. The fabricated particles are processed into meltblown fabric through a meltblown machine. It features high electrical conductivity, high acid and alkali resistance, and high resistance to electrochemical corrosion. Moreover, it begins to have good adhesiveness at 80℃. The electrical conductivity of the material after its hot melting and subsequent cooling is greater than 30 seconds /cm, demonstrating excellent electrical conductivity. It is an excellent material for reducing the contact resistance of two solid materials of electrode materials inside batteries.
