This center is performing the research and development for rechargeable battery and low friction technique, especially focus on solving the problem concerning the nano-interface design. The nano-interfaces of these devices have not been well elucidated, which results in the energy loss at the interfaces and disturbs the development of such devices. This center performs researches according to the plan and directions described below, and will establish the principles for the optimized design of the nano-interfaces for accelerating the development of a highly efficient rechargeable battery and a low friction technique.

Research Plan and Directions

Strategies and Methods for Solving Problems:

Elucidation of structures as well as the dynamics of ion and molecules at electrodes and tribological interfaces on the atomic to nanometer scales.
