Development and research on new anode with three-dimensionally ordered structure for lithium ion battery

Highly patterned cylindrical Sn-Ni alloy with three-dimensionally ordered macroporous (3DOM) structure was successfully prepared by colloidal crystal templating method combined with electroplating process using photoresist substrate. The alloy revealed stable cyclability, and no capacity fade was observed until the two hundredth cycle at a state of charge of 67%. It is concluded that the highly patterned cylindrical Ni-Sn alloy with 3DOM structure is a promising structure.
