Enhancement in lithium storage performances of SiO2/graphene-based nanocomposites prepared by low cost and facile approach

Core-shell structured SiO2@C-Sn/SnO2 nanosphere as an anode material for high-performance lithium-ion batteries

“…For instance, Suh et al [10] devised a 3D porous SiO 2 /C composite which demonstrated excellent cycling stability and a speci c capacity of 294 mAh g − 1 . While Namsar et al [11] used rice husk as a SiO 2 source to prepare nitrogen-doped SiO 2 /rGO nanocomposites that displayed high capacity (385 mAh g − 1 ) and favorable cycling ability. Metal-based materials possess ultra-high lithium embedding capacities-such as monomer Sn that can form a highly lithium-rich alloy with lithium, Li 22 Sn, boasting a theoretical capacity as high as 994 mAh g − 1 .…”

“…The main goal of this research is to determine the most effective method of adding RHs to electrode materials in order to make them more effective anodes. 50,51 Silica is a promising anode material for rechargeable lithiumion batteries (LIBs) due to its low cost and ease of synthesis. The theoretical capacity of this material is several times that of graphite anode (1965 mA h g À1 ).…”
