▎ 摘　　要

NOVELTY - Aqueous MXene (two-dimensional transition metal carbides and nitrides)-based energy storage electrode material screen printing ink comprises oxygen-free water, MXene and energy storage electrode active material. USE - The aqueous MXene-based energy storage electrode material screen printing ink is useful in screen printing substrate (claimed), and micro-battery. ADVANTAGE - The printing ink: has good conductivity and micro-battery of active material. The method: is simple and environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous MXene-based energy storage electrode material screen printing ink comprising (1) mixing raw material system containing MXene aqueous solution and energy storage electrode active material with oxygen-free water to obtain a mixed solution A, and (2) subjecting mixed solution A to ball milling treatment under inert gas atmosphere to obtain aqueous MXene-based energy storage electrode material screen printing ink.
