Title:
The cathode material for rechargeable lithium-ion batteries, a cathode, and a rechargeable lithium-ion battery
Document Type and Number:
Japanese Patent JP6061159
Kind Code:
B2
Abstract:
A negative electrode for lithium-ion secondary battery including a negative electrode that includes a current collector; and a negative-electrode active-material layer formed on a surface of the current collector, and including negative-electrode active-material particles. The negative-electrode active-material particles include an element being capable of sorbing and desorbing lithium ions, and being capable of undergoing an alloying reaction with lithium; or/and an elementary compound being capable of undergoing an alloying reaction with lithium, the negative-electrode active-material particles include particles whose particle diameter is 1 μm or more in an amount of 85% by volume or more thereof when the entirety is taken as 100% by volume, and exhibit a “D10” being 3 μm or more. The negative-electrode active-material layer having a thickness that is 1.4 times or more of a “D90” that said negative-electrode active-material particles exhibit.
