  • SILICON-CARBON CONTAINING ELECTRODE MATERIAL AND SECONDARY BATTERY INCLUDING THE SAME
    Publication number: 20240128443
    Abstract: A silicon-carbon containing electrode material includes a porous carbon structure including pores, and a silicon-containing coating formed on the porous carbon structure. A volume ratio of mesopores is 70% or more based on a total pore volume of the porous carbon structure. A weight ratio of silicon is 30 wt % or more based on a total weight of the electrode material. A high-capacity secondary battery is effectively implemented by using silicon-carbon containing electrode material.
