Study of silicon/polypyrrole composite as anode materials for Li-ion batteries

Silicon and polypyrrole composites were synthesized using high-energy mechanical milling. The polypyrrole acts as a matrix to hold the active silicon grains as they repeatedly alloy with lithium during the operation of a lithium battery. Polypyrrole decreases the initial irreversible capacity loss o...
