Disclosed are an all-solid-state battery that may have uniform deposition of lithium and have excellent durability, and a method of manufacturing the same.

All-solid-state battery with improved durability and method of manufacturing the same

An all solid state battery includes a cathode active material layer disposed in contact with a predetermined area of a cathode current collector, a solid electrolyte layer disposed on the cathode active material layer, and including a central part disposed on the cathode active material layer based on a stack direction of the all solid state battery, and a peripheral part extending from the central part and contacting the cathode current collector while surrounding side surfaces of the cathode active material layer, an anode layer disposed on the solid electrolyte layer and having an area greater than an area of the cathode active material layer but less than an area of the solid electrolyte layer, and a spacer disposed on the solid electrolyte layer and in contact with side surfaces of the anode layer.

All solid state battery with improved durability and method for manufacturing the same

The present disclosure relates to an all-solid-state battery with improved lifetime and an operating method thereof. Specifically, the all-solid-state battery includes a laminate including a unit cell provided with an anode, a cathode, and a solid electrolyte layer interposed between the anode and the cathode, and an expansion layer positioned on at least one surface of the laminate, and expanded by at least any one change in voltage and temperature.

All-solid-state battery with improved lifetime by applying expansion layer and operating method thereof

An all-solid-state battery includes: an anode current collector; a lithium storage layer including a first layer located at an electrolyte-layer side and a second layer located at an anode current collector side, having a higher porosity than the first layer, and including an interface portion and a core portion, which is a remaining portion other than the interface portion; an electrolyte layer; and a cathode layer, wherein the anode current collector, the lithium storage layer, the electrolyte layer, and the cathode layer are sequentially laminated, and the interface portion is in contact with the first layer and has a higher binder content per unit volume than the core portion.

The present disclosure relates to a binder solution for all-solid-state batteries. The binder solution includes a polymer binder, a first solvent, and an ion-conductive additive, wherein the ion-conductive additive includes lithium salt and a second solvent, which is different from the first solvent.

Binder solution for all-solid-state batteries, electrode slurry including the binder solution, and method of manufacturing all-solid-state battery using the electrode slurry

An improved, low porosity, solid electrolyte membrane and a method of manufacturing the solid electrolyte membrane are provided. The low porosity, solid electrolyte membrane significantly improves both mechanical strength and porosity of the membrane, inhibits the growth of lithium dendrites (Li dendrites), and thereby maintains and maximizes electrochemical stability of an all-solid-state battery. This is accomplished by wet-coating a sulfide or oxide solid electrolyte particle with a thermoplastic resin, or a mixture of the thermoplastic resin and a thermosetting resin, using a solvent to prepare a composite and hot-pressing the composite at a relatively low temperature and at a low pressure.
