Al–Si Thin-Film Negative Electrodes for Li-Ion Batteries

Thin-film libraries were characterized for structure, composition, and electrochemical performance using combinatorial and high-throughput techniques. The electrochemical performance of a given composition of cannot be treated as a simple combination of separate reactions of Li with Al and Si because ternary Al–Li–Si phases are present for some compositions and have a significant influence on observed capacities and capacity retention. or appear to be very promising compositions of for Li-ion negative electrode applications.
