Author: Nathiya Kalidas Abstract<\/strong><\/p>\n\n\n\n Silicon has been considered as the most promising\nhigh-capacity anode material for lithium-ion batteries (LIB). Si-based anode\nsuffers from capacity loss stemming from the large volume changes (300%) during\nthe lithiation\/delitiation process. \nPorous silicon (PSi) structures can solve the problem and provide stable\nanodes for the future LIBs. The cost and environmental impact of the anode\nmaterial can be reduced by using agricultural residues. Barley husk is rich in\nphytoliths that are amorphous nanostructures of porous silica. In the present\nstudy, PSi was prepared from barley husk ash containing nanostructured SiO2 and\nreduced to silicon through magnesiothermic reduction so that the nanostructure\nformed by the nature remains. To enhance the electrical conductivity of the PSi\nanode, carbon nanotubes (CNTs) were conjugated to the thermally carbonized\nsurface of PSi particles. Due to the conjugated CNTs the rate performance of\nthe silicon anode was essentially improved.<\/p>\n\n\n\n Full list of posters<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
