Outline of Final Research Achievements

Fabrication of a new high-capacity lithium ion battery anode with good cycle properties was studied. The anode has a unique structure in which a tin active material layer and a copper current collector (an electrode to fix active materials) are connected by carbon nanotubes. This anode was fabricated using electroplating techniques. The developed anode showed superior cycle properties compared to an anode without carbon nanotubes and maintained a capacity of ca. 500 mA h g-1 (1.4-fold higher than currently used graphite active materials) even after 50 cycles.
