Document Type and Number:
WIPO Patent Application WO/2024/082307
Kind Code:
A1
Abstract:
Provided in the present application are a carbonaceous material and a preparation method therefor, a secondary battery comprising same, and an electric device. After the carbonaceous material is subjected to an adsorption test using water vapor and left to stand for 100 h under constant-temperature and constant-humidity conditions of 25°C and 100% RH, the adsorption mass of water vapor is denoted as A, and the initial mass of the carbonaceous material is denoted as B, wherein 0.13 ≤ A/B ≤ 0.50. The present application can improve both the capacity and the initial coulombic efficiency of the carbonaceous material.
