A method for manufacturing a thin film lithium-ion rechargeable battery includes forming a first active material layer on a base, forming an electrolyte layer on the first active material layer, forming a second active material layer on the electrolyte layer, and annealing including emitting a laser beam to at least one amorphous layer among the first active material layer, the electrolyte layer, and the second active material layer to reform the amorphous layer to a crystalline or crystal precursor state. |
