▎ 摘 要
NOVELTY - Preparing densified functional electrode ink applied to rapid ink extrusion technology, comprises adding the pyrrole-modified graphene oxide, the conductive additive, the viscosity regulator and the electrode active material into the solvent, and stirring and dispersing. USE - The fiber-type lithium-ion battery electrode is useful in preparing lithium-ion battery (claimed). ADVANTAGE - The densified functional electrode ink exhibits excellent flexibility and durability when it is used as electrochemical energy storage device, it has ultra-high linear energy density (1.14-1.68 mWh cm-3) and volume energy density. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: electrode ink applied to rapid ink extrusion technology; and preparing a fiber-type lithium-ion battery electrode.
