Vanadium pentoxide-based cathode materials for lithium-ion batteries : morphology control, carbon hybridization, and cation doping
Vanadium pentoxide (V2O5) is a promising cathode material for high-performance lithium-ion batteries (LIBs) because of its high specific capacity, low cost, and abundant source. However, the practical application of V2O5 ...
Recycling bacteria for the synthesis of LiMPO4 (M = Fe, Mn) nanostructures for high-power lithium batteries
In this work, a novel waste-to-resource strategy to convert waste bacteria into a useful class of cathode materials, lithium metal phosphate (LiMPO4; M = Fe, Mn), is presented. Escherichia coli (E. coli) bacteria used for ...
Fabrication of flexible thermoelectric thin film devices by inkjet printing
Ink-jet printing of thermoelectric nanomaterials is successfully used to fabricate flexible thin film TE devices for power generation and cooling.
n-type carbon nanotubes/silver telluride nanohybrid buckypaper with a high-thermoelectric figure of merit
N-type thermoelectric materials was made from CNT buckypapers. We used Ag2Te to achieve electron injection to the CNTs. The thermoelectric characterizations on more than 50 samples show that the CNTs/Ag2Te hybrids exhibit ...
