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： Disclosed is an anodeless all-solid-state battery which may effectively control local volume expansion due to lithium deposited during charging of the battery. The all-solid-state battery includes an anode current collector, an intermediate layer located on the anode current collector, a solid electrolyte layer located on the intermediate layer, a cathode active material layer located on the solid electrolyte layer and including a cathode active material, and a cathode current collector located on the cathode active material layer. The intermediate layer includes carbon particles and metal particles alloyable with lithium, and the carbon particles include a first carbon material, e.g., as a spherical carbon material, and a second carbon material, e.g., a linear carbon material.
