摘要：
A SiCO—Li composite is prepared by causing a reactive silane and/or siloxane having crosslinkable groups to crosslink, sintering the crosslinked product into an inorganic Si—C—O composite, and doping the Si—C—O composite with lithium. When the SiCO—Li composite is used as a negative electrode, a lithium ion secondary cell exhibits good cycle performance, unique discharge characteristics and improved initial efficiency.
