Applications of lithium ion battery have been hampered by a lack of ideal anode materials in terms of capacity and stability. The emergence of metal chalcogenide as a candidate material has reinvigorated the search of a low cost and high capacity material system. However, debate about the underlying mechanisms and overall appraisal of its usage in lithium ion battery system remains. Here, a comprehensive...
Phase‐change memory materials such as the pseudobinary GeTe‐Sb2Te3 compounds have recently gained attention for their good thermoelectric properties, which can be used for power‐generation/cooling applications. In this work, GeTe‐rich Ge–Sb–Te thin films deposited using a radio‐frequency magnetron sputtering method readily exhibit the metastable face‐centered cubic (FCC) phase at room temperature...
Current research has demonstrated the combination of the high theoretical capacity offered by silicon nanoparticles (Si NPs) with graphene-based matrices in order to produce a high energy density and stable lithium ion battery system. However, Si NPs do not mix well with graphene oxide aqueous suspensions and thus create severe segregation of the materials. In this letter, we propose a simple, cost-effective...
