Silicon oxycarbide(SiOC) has emerged as a promising candidate for anode materials in lithium-ion batteries(LIBs) due to its unique properties.However,the low electrical conductivity of SiOC limits its practical applications.Herein,a novel necklace-like nanostructure was fabricated through the sol-gel method by embedding SiOC nanospheres in carbon nanotubes(CNTs) to form a stable electronic pathway within the structure.Controlling the hexadecyl trimethyl ammonium bromide(CTAB)content through CTAB removal and centrifugation to separate SiOC and CNTs@phenylene-bridged mesoporous organosilica(CNTs@PBMO) before the calcination is important to achieve the necklace-like CNTs@SiOC nanostructure.The fabricated porous necklace-like CNTs@SiOC nanostructure not only improved the electrical conductivity but also ensured full utilization of SiOC active sites during discharging/charging along with accelerating ion penetration.As a result,it provided a remarkably long cycling life of up to 1 400 cycles,retaining a specific capacity of 178 mA·h/g.
