Title:
NONAQUEOUS LITHIUM POWER STORAGE ELEMENT
Document Type and Number:
Japanese Patent JP2023050802
Kind Code:
A
Abstract:
To provide a nonaqueous lithium power storage element, suppressed in internal short circuit rate and having excellent input/output characteristics and high durability for storage at high temperatures.SOLUTION: Provided is a nonaqueous lithium power storage element including a positive electrode, a negative electrode, a separator, and a nonaqueous electrolyte. The positive electrode has: an uncoated part where neither an anchor layer nor a positive electrode active material layer is arranged on a positive electrode current collector; an anchor layer coated part where the anchor layer is arranged while the positive electrode active material layer is not arranged; and a positive electrode active material layer coated part where the positive electrode active material layer is arranged on the anchor layer. The negative electrode has a negative electrode active material layer coated part where a negative electrode active material layer is arranged on one side or both sides of a negative electrode current collector. The positive electrode and the negative electrode are arranged such that the anchor layer coated part and the negative electrode active material layer coated part at least partially face each other via the separator.SELECTED DRAWING: Figure 2
