Title:
リチウムイオン二次電池用電解銅箔、リチウムイオン二次電池の負極電極及びリチウムイオン二次電池
Document Type and Number:
Japanese Patent JP5718476
Kind Code:
B2
Abstract:
Provided are an electrodeposited copper foil, a negative electrode that is for a lithium ion secondary battery, and a lithium ion secondary battery into which the electrode is incorporated. The electrodeposited copper foil exhibits good electrical conductivity and superior tensile strength, with no significant decline in tensile strength exhibited even after one hour of heating at 300° C. The negative electrode has heightened cycle properties due to the use of the electrodeposited copper foil as a current collector. Using x-ray diffraction, in the electrodeposited copper foil, in normal conditions, the diffraction intensity (I)<220> in the <220> orientation, the diffraction intensity (I)<200> in the <200> orientation, and the diffraction intensity (I)<111> in the <111> orientation, satisfy the following formula (1): I<220>/{I<220>+I<200>+I<111>}>0.13 (1).
