Abstract
Freeze tape casting (FTC) is a scalable process for fabrication of porous materials including battery electrodes. In FTC, unidirectional pores with low tortuosities are produced, and porosity, pore size, and film thickness can be controlled by adjusting experimental parameters. This low tortuosity porous architecture is advantageous for many types of batteries. For example, a secondary, low tortuosity pore structure in graphite anodes may improve charge acceptance, allowing fast-charging of lithium-ion batteries. Solid-state devices based on ceramic oxides such as variants of LLZO (Li7La3Zr2O12) are enabled when FTC is used to make porous scaffolds of the ion conductor, which is then easily infiltrated by cathode active material and other components. Applying FTC to sulfur electrodes has also been shown to improve rate capability and cycling behavior in lithium/sulfur cells by improving lithium ion transport. In this talk, we will discuss considerations for successful production of electrodes by FTC for these three systems.
