Printable Energy Storage: Stay or Go?

Abstract

In the era of rapidly evolving smart electronic devices, the development of power supplies with miniaturization and versatility is imperative. Prevailing manufacturing approaches for basic energy modules impose limitations on their size and shape design. Printing is an emerging technique to fabricate energy storage systems with tailorable mass loading and compelling energy output, benefiting from elaborate structural configurations and unobstructed charge transports. The derived “printable energy storage” realm is now focusing on materials exploration, ink formulation, and device construction. This contribution aims to illustrate the current state-of-the-art in printable energy storage and identify the existing challenges in the 3D printing design of electrodes. Insights into the future outlooks and directions for the development of this field are provided, with the goal of enabling printable energy storage toward practical applications.

Patterned Micro Flexible Supercapacitors based on the Rapid Transfer-Printing Method

“…Meanwhile, in the pursuit of enhancing electrochemical performance in comparison to traditional carbon-based flexible supercapacitors, such as graphene, recent research has increasingly turned to MXene as a capacitive active material . MXene is a compound with a versatile interlayer structure, derived from transition metal carbides, nitrides, and carbonitrides.…”
