Key Points

This research aims to explore the potential of upcycled waste PET bottles as an anode material for lithium-ion batteries.
Upcycled waste PET bottles were converted into phosphorus-doped hard carbon through one-step H3PO4 pyrolysis.
Anode performance was tested at different current densities (0.2 A g−1 and 2 A g−1).
The optimized anode material achieved a capacity of 765 mAh g−1 at 0.2 A g−1.
At a higher current density of 2 A g−1, the capacity was 531 mAh g−1.

Implication

Demonstrates high-performance anode material from waste PET bottles, highlighting recycling potential.

Abstract
