Polymer-derived silicon carbonitride (SiCN) materials have been synthesized via pyrolyzing from five poly(silylcarbondiimide)s with different contents of carbon (labeled as 1-5#). The morphol. and structure measurements show the SiCN materials are the mixtures of nanocrystals of SiC, Si3N4, and graphite. The SiCN materials have been used as anodes for lithium ion batteries (LIBs). Among the five polymer-derived SiCN materials, the 5#SiCN derived from dichloromethylvinylsilane and di-n-octyldichlorosilane, has the best cycle stability and high-rate performance at the low cut-off voltage of 0.01-1.0 V. In lithium-ion half-cells, the specific delithiation capacity of that 5#SiCN anode still remains at 826.7 mAh g-1 after 100 charge/discharge cycles; it can even deliver the capacity above 550 mAh g-1 at high current densities of 1.6 and 2 A g-1. In lithium-ion full cells, the 5#SiCN anode works well with NCM com. cathode. The outstanding electrochem. performance of 5#SiCN anode is attributed to two factors: (1) the formation of stable and compact SEI layer on the anode surface anode, which protects the electrode cracking during the charge/discharge cycling; (2) a large amount of carbon component the less Si3N4 phase in the 5#SiCN structure, which provides electrochem. reactive and conductive environment in the SiCN structure, benefits the lithiation/delithiation process. In addition, we explore the reason for the capacity fading of these SiCN anodes.
