In this study, rice husks were used as a source of silicon dioxide for the synthesis of silicon nanoparticles (Si NPs) through magnesiothermic reduction process. The Si NPs were further used to prepare a binder-free composite system comprising Si NPs and graphene as an anode material for lithium ion battery system (LiBs). The composite system fabricated from rice husk-based Si NPs (RH-Si NPs) yielded an initial capacity of 1000 mA h g-1 at high applied current density of 1000 mA g-1. This study opens up the use of waste materials such as rice husk as a sustainable source of key components in advanced technology applications. This journal is © the Partner Organisations 2014. |
