  In this work, we present the electrochemical behavior and microstructural analysis of silicon oxycarbide (SiOC) ceramics influenced by an addition of polystyrene (PS). Polymer-derived ceramics were obtained by pyrolysis (1000°C, Ar atmosphere) of different polysiloxanes prepared by sol–gel synthesis. This method is very effective to obtain desired composition of final ceramic. Two alkoxysilanes phenylthriethoxysilane and diphenyldimethoxysilane...

  Polymer derived ceramics (PDCs) have attracted attention as alternative anode material for Li-ion batteries. It has been found that ternary SiOC and SiCN ceramics obtained through pyrolysis of various preceramic polymers display high reversible capacities of 500 – 650 mAh/g. In this work we try to correlate the electrochemical performance of polymer derived silicon oxycarbide with its chemical composition and microstructural features....

  Polymer derived carbon-rich SiOC ceramics are prepared from polysiloxane precursors through a pyrolysis process at 1000 °C using pure argon and argon/hydrogen mixture as pyrolysis atmosphere. The precursor is synthesized from a linear (Si–H)-containing polysiloxane cross-linked with divinylbenzene using hydrosilylation reaction in the presence of a platinum catalyst. Pyrolysis in Ar/H2 mixtures, compared to the treatment under...

  - SOLID STATE IONICS - Year 2014

  Polymer derived silicon oxycarbide (SiOC) ceramics are investigated as potential anodes for lithiumion batteries. Different SiOC ceramics are prepared by pyrolysis (1000 °C and 1400 °C under controlled argon atmosphere) of polysiloxanes ceramic precursors. Preceramic polymers are synthesized using the sol–gel method. Phenyltriethoxysilane (PhTES) and methyltriethoxysilane (MTES) have been used as starting precursors and mixed with...
