Outline of Final Research Achievements

The suppression of dendritic growth observed in electrodeposition has been achieved not by using additives but by using nanoporous electrodes as host matrices. In order to suppress dendritic growth using nanoporous electrodes, it is obvious that metal ions must be supplied effectively. In addition, coexisting ions must be selected appropriately. In particular, cations with a large ionic diameter and thus low charge density are preferable. Low charge density cations, e.x. tetraethylammonium cations, enhance the supply of metal anions such as [PtCl4]2-.
