مستخلص: With the rapid growth of solar energy, recycling and reuse of end-of-life solar modules have become a critical issue. In light of this, a simple, yet environmentally friendly, ball milling process was used to transform the recycled Si of waste solar cells into a lithium ion battery anode material. The ball-milled recycled Si was further combined with a carbon fiber paper (CP) substrate to fabricate a composite electrode. The milling time and rotation speed were optimized to form a Si/SiOx/Al2O3 active material with a moderate primary particle size, agglomeration extent, and oxidation states of Si and Al. These features allow the recycled Si to exhibit promising cycling and rate performances. Additionally, introducing a hydrothermally treated CP substrate can further improve the electrochemical performance of the composite electrode, delivering a high discharge capacity of 1603 mA h g-1 after 100 cycles (capacity retention of approximately 91% (200 mA g-1)) and 813 mA h g-1 at 2000 mA g-1, due to the presence of nitrogen-containing groups, particularly the pyridinic-N group. This is evidenced by the reduced solid electrolyte interface and charge transfer resistances and the increased ion diffusion coefficient of the Si/SiOx/Al2O3-based cell. [ABSTRACT FROM AUTHOR]
