Dr. Takeshi Abe
Batteries Next Generation
Dr. Abe received his BChE degree from Department of Industrial Chemistry, Faculty of Engineering, Kyoto University in 1992, and he has MS and PhD degrees from Graduate School of Engineering, Kyoto University.
Upon completion of his PhD degree in 1996, he joined Graduate School of Engineering, Kyoto University as a Research Associate in 1997 and was promoted to Associate in 2002 and then to Professor in 2009.
Dr. Abe initially devoted to the graphite intercalation compounds and graphite negative electrode for lithium-ion batteries. His current research is based on lithium ion batteries and s-block metal batteries such as rechargeable magnesium batteries, focusing on interfacial phenomena. He has to his credit about over peer-reviewed 180 papers and several co-edited books about new technology for advance rechargeable batteries and electrochemistry.
His technical contributions have been recognized by awards of Sano Award for Young Scientists, Electrochemical Society of Japan in 2002, Battery Technology Award in 2006 from The Committee of Battery technology, The Electrochemical Society, Japan, Research Award, Carbon Society, Japan.
He is Associate Editor of Journal of Power Sources, editorial board of “Ionics” and Journal of New Energy.
In 1857, Plante developed lead-acid batteries followed by Nickel Cadmium batteries in 1899. Then we had to wait for almost 100 years to see new high technology batteries of Nickel metal hydride batteries and Lithium-ion batteries. The rapid development of the both batteries has expanded the application fields of not only portable electronic devices but also hybrid electric vehicles and pure electric vehicles. In addition, stationary use of rechargeable batteries has attracted much attention. Now rechargeable batteries are required to enhance further performance such as energy densities, power densities, safety, etc., which leads to the motive force for the development of new batteries. The direction of new batteries will be categorized by three: 1) high power densities with high safety, 2) high energy densities with low cost, and 3) beyond lithium-ion batteries. Rechargeable batteries with high power and safety will be Zinc-nickel batteries, which had been extensively developed by battery makers during 1970-1980. Zinc negative electrode should be re-examined to replace the metal hydride. Sodium ion batteries may be the candidates to replace NaS (sodium-sulfur) batteries. Beyond lithium, this is the most difficult one. Several candidates of multi-electron systems, metal-air, etc. will be introduced in the conference.

Reader in Unmanned Air Vehicles
Energy conservation techniques - Increasing the endurance of small UAVs
Dr. Prior has been working in the field of Physics & Robotics for the past 23
years. His research interest in autonomous systems relates to a shortlisted entry to
the MoD Grand Challenge event in August 2008, where he led a team to design,
develop and construct a novel unmanned aerial vehicle, which consisted of a
co-axial tri-rotor arrangement. On the basis of this, he founded the Autonomous
Systems Lab and has been researching with a small team of staff/students
working on defence-related robotic technologies. He is on editorial board for the
International Journal of Micro Air Vehicles and has published widely on the
subject. Recent work involved developing the winning entry to the DARPA
UAVForge challenge, and the design and development of a series of
Nanotechnology platforms which were demonstrated and flown at the DSEi
exhibition at the Excel Centre in London.
All small Unmanned Aircraft (UA) have severe limitations from a lack of
endurance capability. This is a direct result of using battery technologies which
are limited in their capacity, current capability, mass and energy density.
The most widely used chemistry in small battery powered UAVs is Li-Po with its
peak energy density of about 200 Wh/kg. Much research has been directed at
finding alternative power sources, from Solar, Hydrogen Fuel Cells to Nuclear
batteries. The latest contender is Li-S chemistries which appear to offer energy
densities of up to 400 Wh/kg within the next 2 years. Li-S batteries claim to be
safer in terms of damage tolerance and the lack of thermal runaway, which can
be an issue with the current generation Li-Po batteries.
This presentation will outline the alternatives and point towards the likely future
direction of this technology. The author will also present other design strategies
and design tools which help to promote the efficient use of power within these
types of Unmanned Aircraft.

One hundred years from now, vehicles will be powered by a combination of
motor, capacitor, and wireless technologies. Electric-motor-driven vehicles
(EVs) will be widely used and will be linked to the electric power system
infrastructure. The vehicles will operate through frequent electric charging, as is
the case with electric trains. Long-life super-capacitors will play an important
role in the future for charging of EVs. Wireless power transfer based on
magnetic resonance is an extremely important technique. In a laboratory
experiment, this technique enabled a power transfer with more than 95%
efficiency at a distance of 1 m. One hundred years from now, this technique will
be greatly improved; e.g., it could be possible to have a 10 kW power transfer
over a distance as long as 10 m. This level of improvement will drastically
change how cars are powered. In addition, to improve the energy efficiency and
safety of future EVs, the implementation of novel motion control techniques is
crucial. These techniques would be based on the excellent controllability of
electric motor. The combination of electric motors, super-capacitors, and
wireless power transfer eliminates the requirement for engines,
high-performance Li-ion batteries, and quick charging stations.
