Researchers propose reason for capacity loss in metal-oxide battery materials

Green Car Congress

Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies. However, their capacity fades very rapidly. Top: Fe 3 O 4 (iron oxide) sample after three cycles.

New Coaxial Nanocables Show Enhanced Rate, Energy and Cycling Performance as Li-ion Electrode Materials; Yin-Yang Principle Extensible to Other Electrochemical Storage Devices

Green Car Congress

Researchers in China and Germany have coated carbon nanotubes (CNT) with a nanoporous layer of TiO 2 to create coaxial nanocables for use as electrode materials in Li-ion batteries (LIB). Carbon provides sufficient electronic conductivity but lacks sufficient ion conductivity. It allows for a rapid access of ions to the CNT.
