Title:
LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2022114216
Kind Code:
A
Abstract:
To provide means for improving charge/discharge rate characteristics in a lithium deposition type lithium secondary battery.SOLUTION: A lithium secondary battery includes a power generation element including a positive electrode that has a positive electrode active material layer containing a positive electrode active material capable of intercalating and deintercalating lithium ions, a negative electrode that has a negative electrode current collector and on which lithium metal is deposited on the negative electrode current collector during charging, and a solid electrolyte layer interposed between the positive electrode and the negative electrode, and a pressurizing member that pressurizes the power generation element in the stacking direction with predetermined pressure, and the ten-point average roughness (RzJIS) of the surface of the negative electrode current collector on the solid electrolyte layer side is controlled in the range of 3 to 50 μm.SELECTED DRAWING: Figure 1
