The present invention relates to a method and apparatus for manufacturing a thin film battery having a composite multilayer electrolyte having a soft electrolyte between a cathode and / or a hard electrolyte covering an anode, and a battery obtained as a result.n n n In the preferred embodiment, the on both sides covered by a hard electrolytic cathode material (that is, LiC O O 2) respectively with the foil-core cathode sheet (foil-core cathode sheets), and a rigid electrolyte on each side Foil-core anode sheets with an anode material (i.e. lithium metal) coated by means of a soft electrolyte (i.e. polymer gel) alternately inserted between their cathode sheet and the anode sheet Laminated.n n n The rigid glass-like electrolyte layer yields a smooth hard anode-lithium metal layer when charged, but has randomly spaced pinholes / defects when very thin.n n n When the hard layer is formed at the anode and the cathode, the dendrite-short-generating defect in one electrode does not coincide with the defect in the other electrode.n n n All of the soft electrolyte layers conduct ions through gaps between the hard electrolyte layers and fill pinholes.n n n n Soft electrolytes, hard electrolytes, polymer gels, cathodes, anodes, thin film batteries, lithium metals, pinholes, defects, dendritic structures, composite multilayer electrolytes. |
