Nanocomposite polymer electrolytes for lithium batteries

Article Abstract:

Ceramic powders of nanoscale particle size can be added to PEO-LiX polymer electrolytes to develop solid-state PEO-LiX composite polymer electrolytes. These electrolytes show very good mechanical stability and high ionic conductivity in the range of 30 degrees C to 80 degrees C. It is believed that this research offers the first experimental evidence to back up previous theories about the role of the ceramic filler in promoting increased Li+ transport through a surface mechanism. It may be possible to develop polymer electrolytes with a true solid-state configuration linked with high conductivity and high lithium ion transference number.

Non-volatile memory device based on mobile protons in SiO2 thin films

Article Abstract:

Mobile hydrogen ions, when introduced into the buried oxide layer of silicon/silicon-dioxide structures, have a positive affect on SiO2 thin film by becoming a component part of a non-volatile memory device. Studies show mobile protons that remain in the oxide layer of the film are rearranged when an electric field is applied to the film at 20 degrees centigrade. Such memory devices are likely to challenge modern silicon-based memory technologies for market share.
