Title:
HARD CARBON MATERIAL AND PREPARATION METHOD THEREFOR, ELECTROCHEMICAL DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/077933
Kind Code:
A1
Abstract:
The present application relates to a hard carbon material and a preparation method therefor, an electrochemical device, and an electronic device. The hard carbon material comprises a porous framework, a first element and zinc, wherein the first element comprises one or more of nitrogen, sulfur, boron, phosphorus and selenium. The content of the first element relative to the total mass of the hard carbon material is denoted as A1%; and the content of zinc relative to the total mass of the hard carbon material is denoted as A2%, wherein the hard carbon material satisfies: 1.5 ≤ A1/A2 ≤ 5. When the hard carbon material of the present application is used in an electrochemical device, the energy density of the electrochemical device can be significantly improved.
