Using a simple stencil printing process followed by ultraviolet cross-linking, researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea) have demonstrated a new type of Printable Solid-State (PRISS) Lithium-ion batteries designed through successive layers of curable composite materials.
The PRISS Batteries consist of a solid-state composite electrolyte (SCE) layer and SCE matrix-embedded electrodes, which can be printed on just about any object of any shape, as it is possible with today’s stencil process. The researchers successfully tuned the rheological properties of the SCE paste and electrode slurry to give them thixotropic fluid characteristics suitable for complex deposition patterns on non-flat objects. They also had to design a high boiling point electrolyte to make the PRISS batteries compatible with heat curing.
Circumventing solvent-drying and liquid-electrolyte injection process steps, while removing the need for conventional microporous separator membranes, makes the printable batteries truly shape-conformable.
