Abstract

With the development of electronics and electric vehicles, high-performance batteries with high energy density, high safety, and aesthetic diversity are greatly needed as dominating power sources. However, the electrodes and electrolytes fabricated with traditional techniques have limited form factors, mechanical flexibility, and poor performance. Extrusion-type 3D printing techniques have thus been applied to fabricate 3D batteries with high performance since 3D printing techniques have great advantages in the fabrication of complex 3D structures and geometric shapes from various materials. The research in this thesis aims at fabricating high-performance Li/Na batteries via 3D printing of advanced electrodes and solid electrolytes.
