摘要： An all-solid-state battery having an increased lifespan is equipped with a pressure pad layer. More particularly, the all-solid-state battery includes a unit cell and a pressuring pad layer. The unit cell is composed of a cathode, an anode, and a solid electrolyte layer positioned between the cathode and the anode. The pressurizing pad layer is positioned on each side of the unit cell and includes a non-porous upper layer, a non-porous lower layer, and a porous core layer positioned between the non-porous upper layer and the non-porous lower layer.

摘要： A pouch type all-solid-state battery including a reference electrode is disclosed. In the all-solid-state battery, a potential variation of each electrode is accurately measured because the ion transfer path between the reference electrode and a positive electrode/negative electrode is short. Accordingly, the all-solid-state battery secures a desired cell performance while having battery specifications similar to actual battery specifications.
