Fabrication of a PI-CNT-Cu current collector via electrospinning and copper plating.
Evaluation of surface roughness to improve adhesion and reduce interfacial resistance.
Testing capacity retention over 190 cycles in a lithium-ion battery setup.
The developed anode maintains 95.29% capacity after 190 charging cycles.
Enhanced adhesion leads to lower interfacial resistance.

Implication

Research demonstrates enhanced capacity retention in lithium-ion batteries using a new composite anode.

Abstract

A PI-CNT-Cu bidirectional conductivity current collector is fabricated by electrospinning and Cu plating. Its rough surface enhances adhesion, lowering interfacial resistance. The graphite/PI-CNT-Cu anode retains 95.29% capacity after 190 cycles.
