High-purity iron pyrite (FeS2) nanowires as high-capacity nanostructured cathodes for lithium-ion batteries.
Iron pyrite is an earth-abundant and inexpensive material that has long been interesting for electrochemical energy storage and solar energy conversion. A large-scale conversion synthesis of phase-pure pyrite nanowires has been developed for the first time. Nano-pyrite cathodes exhibited high Li-storage capacity and excellent capacity retention in Li/pyrite batteries using a liquid electrolyte,...
متن کاملLi2MnSiO4 Nanostructured Cathodes for Rechargeable Lithium-Ion Batteries
Rechargeable lithium-ion battery technology dominates the portable electronics market following the rapid growth in demand since the introduction of the first, commercial lithium-ion battery by Sony in 1990 [1]. Motivated by concerns for global warming and environmental degradation, researchers have focused on extending the use of rechargeable lithium-ion batteries to large-scale applications. ...
متن کاملNanoporous LiMn2O4 nanosheets with exposed {111} facets as cathodes for highly reversible lithium-ion batteries†
Control over porosity and exposed highly reactive facets is challenging in the area of materials science. Materials with high porosity and reactivity of exposed facets are favorable candidates in catalysis and energy storage. Here we demonstrate a facile template-free route to synthesize nanoporous LiMn2O4 nanosheets composed of single-crystalline LiMn2O4 nanorods with exposed {111} facets via ...
متن کاملSpinel LiMn2O4 nanorods as lithium ion battery cathodes.
Spinel LiMn2O4 is a low-cost, environmentally friendly, and highly abundant material for Li-ion battery cathodes. Here, we report the hydrothermal synthesis of single-crystalline beta-MnO2 nanorods and their chemical conversion into free-standing single-crystalline LiMn2O4 nanorods using a simple solid-state reaction. The LiMn2O4 nanorods have an average diameter of 130 nm and length of 1.2 mic...
متن کاملFacile Synthesis of V₂O₅ Hollow Spheres as Advanced Cathodes for High-Performance Lithium-Ion Batteries.
Three-dimensional V₂O₅ hollow structures have been prepared through a simple synthesis strategy combining solvothermal treatment and a subsequent thermal annealing. The V₂O₅ materials are composed of microspheres 2-3 μm in diameter and with a distinct hollow interior. The as-synthesized V₂O₅ hollow microspheres, when evaluated as a cathode material for lithium-ion batteries, can deliver a speci...
