Advantageously, the fatty acid capping, avoiding particle agglomeration upon the synthesis of the TiO2 nanoparticles, is subsequently carbonized. The resulting carbon surface layer surrounding the TiO2 nanoparticles further prevents particle agglomeration upon electrode preparation and significantly improves the electric conductivity of the thus resulting electrodes.
Commercial Opportunities: Electrodes based on this TiO2/C composite provide an improved cycling stability and an increased specific capacity compared to the use of conventional TiO2 anodes. Additionally, they show an advanced high rate capability, particularly when compared to common graphite based anodes, still mostly used in current commercial lithium-ion batteries.
Moreover, as TiO2 based anodes operate within the electrochemical stability window of conventional liquid organic electrolytes, they offer improved operating safety compared to usual graphite systems.
Further advantages of the herein presented invention are amongst others the cost-effective, fully environmentally friendly and easy up-scalable manufacturing process, which is thus easy to be integrated into an industrial production line for modern secondary batteries.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
