Disclosed is a method of manufacturing an all-solid state battery. The method includes coating a first slung or composition having on a substrate to form a first electrolyte layer a predetermined thickness, coating a second slurry or composition on the first electrolyte layer to form a second electrolyte layer having a predetermined thickness, laminating an electrode layer on the second electrolyte layer, bonding the electrode layer to the second electrolyte layer through pressing, and removing the substrate from the first electrolyte layer. The first slung or composition of the first electrolyte layer has content of a binder less than that of the second slurry or composition of the second electrolyte layer, and thus, the substrate may be easily removed from the first electrolyte layer.

Disclsoed are a bipolar electrode, a bipolar all-solid battery manufactured by using the same, and a manufacturing method thereof. The bipolar electrode includes: a solid electrolyte; an anode slurry and a cathode slurry, each of which is provided on a first surface and a second surface of the solid electrolyte; spacers provided in the anode slurry and the cathode slurry; and a metal substrate provided in the anode slurry and the cathode slurry. Accordingly, an output and an energy density may be improved by cell integration through minimization of thickness of the cathode, the anode, and the electrolyte of the all-solid battery. Further, when the bipolar all-solid battery is manufactured using high voltage stability characteristic of the solid electrolyte, difference in an elongation rate or a compression rate among the elements may be reduced to secure or improve process stability and to minimize a cell defective rate.

A battery system improving operation reliability of a swelling current interrupt device (CID) is provided. The battery system includes a cooling plate that forms an appearance of a battery in which the swelling CID interrupting a current flow is mounted and includes a swelling aperture formed therein. The swelling aperture induces an expansion of a pouch in which the swelling CID is embedded. Therefore, since the swelling aperture is formed in the cooling plate, improved operation reliability of the swelling CID than a battery system according to related art in which operation reliability was varied based on a thickness of a pouch cell is obtained.

A method of manufacturing an all-solid-state battery electrode, an all-solid-state battery electrode manufactured by the method, and an all-solid-state battery including the electrode are disclosed. In the method, a specific type of binder included in the electrode is prepared in a fiber form by applying pressure to the binder under specific conditions, so that the fiber-form binder thus prepared has an average fineness that satisfies a specific range. Therefore, the all-solid-state battery including the electrode has an advantage of having high capacity even in the case of electrode thickening for high loading.

An argyrodite-based solid electrolyte may contain a compound having a novel composition calculated by simulation of Ab initio molecular dynamics (AIMD). The solid electrolyte containing a compound having a novel composition that satisfies a certain range of monoatomic disorder (è) and a certain range of standard deviation (STD) of the size of the area formed as migration paths of Li metals, which are calculated by AIMD simulation, has an advantage of excellent ion conductivity due to promoted diffusion of monoatoms in the area.
