Title:
LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/089128
Kind Code:
A1
Abstract:
The present invention relates to the technical field of lithium-ion batteries; disclosed is a lithium-ion battery. The lithium-ion battery comprises a positive electrode, a negative electrode, a separator placed between the positive and negative electrodes, and a non-aqueous electrolyte solution; the positive electrode material of said positive electrode contains the positive electrode active material LiNixCoyMzO2, wherein M is selected from Mn and/or Al, 0.5 ≤ x ≤ 1, 0 ≤ y ≤ 0.5, 0 ≤ z ≤ 0.5, and x + y + z ≤ 1; the non-aqueous electrolyte solution contains an organic solvent, a lithium salt, and the compound represented by the formula (1). The lithium-ion battery has significantly improved chemical performance when cycled and stored at high temperatures.
