Graphite-supported 2,2′-bipyridine-capped ultrafine tin nanoparticles for anodes of lithium-ion batteries

Novel synthesis of high performance anode materials for lithium-ion batteries (LIBs)

“…As an approach to synthesize stable nanosized tin-based anode materials, Nabais et al reported a particular reductive approach using NaBH 4 as the reducing agent and 2,2 0 -bipyridine-SnCl 2 as a novel precursor. 137 Solid 2,2 0 -bipyridine-SnCl 2 complexes were prepared by adding 2,2 0 -bipyridine to SnCl 2 in a methanol mixture. The complex (dispersed in methanol solution) was further reduced by NaBH 4 in the presence of graphite, such that Sn nanoparticles were dispersed onto the graphite surface aer the reduction process to yield a tin-graphite composite material: 137…”

Ultrafast preparation of three-dimensional porous tin–graphene composites with superior lithium ion storage

“…And similar phenomena have been observed in Snbased composites by different groups. 33,40,41 Moreover, according to the above XRD analysis, most of Sn particles in 3D Sn-GNS have not been oxidized. It is well known that GO contains abundant oxygenated functional groups, such as C-C, C]O, O-C]O, C-O groups and so on.…”
