Abstract
A refined microcrystalline electrode manufacturing method is provided. The refined microcrystalline electrode manufacturing method includes the following step. First, an active material electrode layer is subjected to a conventional thermal annealing (CTA) process in an oxygen-containing environment at a first temperature interval to form an active material crystallization precursor; the active material crystallization precursor is subjected to a rapid thermal annealing (RTA) process in the oxygen-containing environment at a second temperature interval to form an active material coating layer with uniformly distributed fine microcrystal grains, wherein the temperature range of the second temperature interval is greater than the temperature range of the first temperature interval. In addition, a thin film battery and a thin film battery manufacturing method are also provided.
