Abstract
A method for manufacturing polycrystalline electrode is provided, which may include the following steps: providing a conductive substrate; using a film coating method to deposit an active material on one side of the conductive substrate by a hydrogen-containing plasma source to form an electrode layer; executing a thermal annealing process for the electrode layer in an oxygen-containing environment. The grains of the polycrystalline electrode manufactured by the method will be more uniform in size, which can significantly increase the volumetric energy density of thin-film battery to significantly improve its performance.
