Recent Developments in Silicon Anode Materials for High Performance Lithium-Ion Batteries

Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Silicides: Promising Thermoelectric Materials

Higher transition metal silicides are very well-suited for anisotropic thermoelectric conversion. Essential anisotropy of the Seebeck coefficient, together with good mechanical properties, allows production of reliable anisotropic thermoelectric converters.

Electrode Materials for Lithium Ion Batteries

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.
