Thin cathode for thermal batteries using a tape-casting process

Abstract

Thin cathodes for thermal batteries with good homogeneity and a reproducible thickness were prepared using a tape-casting process. A single cell fabricated with a 100 pm thick cathode using tape-casting process exhibited a specific capacity of 1934.08 A s/g. In contrast, a single cell fabricated with a pellet type 500 pm thick cathode demonstrated a specific capacity of 1000.25 A s/g. The thin cathode, which exhibited excellent utilization of the electrode material due to the optimal thickness from an electrochemical point of view, showed good mechanical strength and excellent electrochemical properties making it suitable for use in thermal batteries.
