Abstract
The present application provides a carbon material, a method for preparing the same, and a secondary battery and an electrical device comprising the same. The carbon material includes a pore structure, wherein the carbon material satisfies 0.150≤ID/IG≤0.280, with ID indicating an intensity of the D peak of the Raman spectrum at 1350±50 cm−1 and IG indicating an intensity of the G peak of the Raman spectrum at 1580±50 cm−1. The carbon material provided in the present application can make the secondary battery have high initial columbic efficiency, high energy density, good cycling performance and storage performance.
