POROUS CARBONIZED COMPOSITE MATERIAL FOR HIGH-PERFORMING SILICON ANODES

摘要

An electrode material for an electrochemical cell, such as a lithium ion battery or a lithium sulfur battery, is provided. The electrode may be a negative anode. The electrode material comprises a composite comprising a porous matrix comprising a carbonized material. The electrode material further comprises a plurality of silicon particles homogeneously dispersed in the porous matrix of carbonized material. Each silicon particle of the plurality has an average particle diameter of greater than or equal to about 5 nanometers and less than or equal to about 20 micrometers.
