| Abstract(E) | We have developed high-power energy storage devices using nano-sized (battery) redox electrode materials, which we call Super Redox Capacitors (SRCs), for future automotive applications. As the nano-sized redox electrode materials, the nano-sized lithium titanate (LTO) and nano-sized lithium vanadium phosphate (LVP)/multiwalled carbon nanotube (MWCNT) composite were successfully prepared through collaborative work with Tokyo University of Agriculture and Technology. Two different SRC cells were assembled and their electrochemical performances were characterized; i) nano-LTO//conventional lithium manganate (LMO) and ii) nano-sized LTO//nano-sized LVP composite. Both SRC cells showed high power performances of 5-7 kW/L with over10 times higher energy density than the conventional EDLC. In addition, SRC cells also exhibited an excellent low temperature performance down to -40 oC, showing that the SRCs possess promising performance as a high-power energy storage device for automotive applications. |
