Abstract
Thin-film Fe-Si-Zn libraries were investigated as negative electrode materials for Li-ion batteries using combinatorial and high-throughput techniques. X-ray diffraction and electron microprobe measurements were used to characterize the library structure. A large amorphous region exists in Si-rich compositions of this system. The electrochemistry of numerous compositions of Fe-Si-Zn materials was determined near room temperature. Both Zn and Fe additions to Si were found to suppress the formation of Li15Si4 during cycling.
