Our teams have been restructured as of year 2018.
TL: Masahiro Tatsumisago (Prof., Osaka Prefecture University) Labo HP
We conduct research toward the practical application of all-solid-state batteries in which the electrolyte solution has been replaced by a solid electrolyte.
All-solid-state batteries are leakage-free safe batteries without flammable electrolyte solutions, and are thus expected to be used as power sources such as for cars.We study elemental technologies such as interface construction, materials processing and battery designs that are suitable for sulfide-based and oxide-based inorganic solid electrolytes under the two subteams, Sulfide and Oxide.
The Sulfide subteam has been accelerating the process toward practical application through collaboration with the Consortium for Lithium Ion Battery Technology and Evaluation Center (LIBTEC).
TL: Masayoshi Watanabe (Prof., Yokohama National University) Labo HP
We conduct studies toward the practical application of high energy density batteries that use sulfur, which have no resource constraints as the cathode, lithium metal or silicon, both of which have high theoretical specific capacity, as the anode, and ionic liquid as the electrolyte.
In addition to the non-volatile flame-resistant nature of ionic liquids, its heterolytic nature can overcome the fatal flaw of sulfur cathodes, the problem of elution of the active material. By optimizing the nanostructure of the cathode and anode, the problems of volume change and insulation can also be minimized.
The Lithium-Sulfur battery team has been accelerating the process toward practical application through collaboration with the Consortium for Lithium Ion Battery Technology and Evaluation Center (LIBTEC).

We examine the potential of a wide range of next-next generation batteries including Mg batteries that employ bivalent ions as mobile ions, metal-air batteries that have high theoretical energy density, and batteries that employ anions as mobile ions.
We attempt to demonstrate batteries that employ novel ion movements with double to triple the performance of existing batteries, through coherent research from examination of materials to battery cells and thinking beyond the framework of past studies, with the aim of developing batteries that can be used in electric cars and natural energy use.

Experts from each team work in collaboration on issues shared by all types of batteries studied at ALCA-SPRING.
The Special unit for Lithium metal anode research works on solving issues such as the safety and self-discharge characteristic of lithium metal, which has a high theoretical specific capacity.
The Evaluation, analysis & common material technology group employs the facilities at the Battery Research Platforms in order to assist with procedures shared by all teams such as advanced and sophisticated analysis, battery assembling, and provision of commonly used materials.
