Abstract
Official abstract text for this publication.
A method of applying uniform pressure to an all-solid-state battery during activation of the battery and preventing an interface contact surface from being separated as the result of gas generated in the all-solid-state battery is provided. This method increases the lifespan of the battery and an all-solid-state battery manufactured using the same method.
First claim
Opening claim text (preview).
1 . An all-solid-state battery comprising: a positive electrode; a negative electrode; a solid electrolyte; and a pouch or a can accommodating the positive electrode, the negative electrode, and the solid electrolyte, wherein the all-solid-state battery is manufactured by placing the all-solid-state battery in a jig, a fluid is placed between at least one surface of the pouch or the can and the jig, and charging and discharging the all-solid-state battery while uniformly pressing the at least one surface of the pouch or the can using the fluid. 2 . The all-solid-state battery of claim 1 , wherein the at least one surface of the pouch is rough, partially protruded, or partially recessed. 3 . The all-solid-state battery of claim 1 , wherein the pouch or the can is pressed under a pressure of 50 kgf/cm 2 to 5000 kgf/cm 2 . 4 . The all-solid-state battery of claim 1 , wherein the fluid is gas or liquid. 5 . The all-solid-state battery of claim 1 , wherein the pouch or the can comprises a coating layer to reduce reactivity with the fluid. 6 . An all-solid-state battery manufacturing apparatus comprising: a jig configured to place an all-solid-state battery; and a fluid configured to be placed between at least one surface of an all-solid-state battery and the jig. 7 . The all-solid-state battery manufacturing apparatus of claim 6 , wherein the jig comprises a layer or a step configured to prevent movement of the fluid. 8 . The all-solid-state battery manufacturing apparatus of claim 6 , wherein the fluid has an area equal to or greater than the area of the largest surface of the all-solid-state battery.
