More Information
Summary:The invention relates to a lithium-silicon-carbon composite material, especially formed as a surface-coated lithium-silicon-carbon composite material, comprising a porous carbon scaffold comprising micropores and mesopores and a total pore volume no less than 0.5 cm3/g; a silicon content from 30% to 70%, including 30% and 70%; a Li content from 2% to 20%, including 2% and 20%; and an at least partly applied first surface coating layer forming a surface coating on a surface area of the lithium-silicon-carbon composite comprising one or multiple elements of Li, B, Al, Si, P, Ti, Zr, Nb and/or W.
