Hierarchical MoS2 nanosheet/active carbon fiber cloth as a binder-free and free-standing anode for lithium-ion batteries.
Owing to the layered structure and high theoretical capacity, MoS2 has attracted more and more interest as a potential anode material for lithium-ion batteries. However, it suffers from rapid capacity decay and low rate capability. In this work, we introduce a novel hierarchical material consisting of ultrathin MoS2 nanosheets grown on the surface of an active carbon fiber (ACF) cloth fabricate...
متن کاملHierarchical MnCo2O4 nanosheet arrays/carbon cloths as integrated anodes for lithium-ion batteries with improved performance.
To solve the reduced output voltage caused by the high lithium redox potential of Co3O4 when applied as an anode material in full cells, an effective strategy is to partially replace Co by Mn to form MnCo2O4 without changing the original crystal structure. Herein, 3D hierarchical MnCo2O4 nanosheets arrays grown via a hydrothermal method on carbon cloths, as binder-free anodes for lithium-ion ba...

MoS(2)@CMK-3 nanocomposite consisting of confined nanosized MoS(2) in CMK-3 carbon matrix exhibits much improved cycling performance and rate capability due to the enlarged interlayer distance and favorable conductivity.
متن کاملFacile synthesis and electrochemical performances of hollow graphene spheres as anode material for lithium-ion batteries
UNLABELLED The hollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion technique, which were prepared from natural flake graphite by oxidation and ultrasonic treatment. The hollow graphene oxide spheres were reduced to hollow graphene spheres at 500°C for 3 h under an atmosphere of Ar(95%)/H2(5%). The first reversible spec...
متن کاملOne-pot synthesis of ZnFe2O4/C hollow spheres as superior anode materials for lithium ion batteries.
ZnFe(2)O(4)/C hollow spheres have been synthesized via a facile solvothermal route using low cost raw materials. The resulting composite showed a very high specific capacity of 841 mAh g(-1) after 30 cycles and good rate capability.
