Carbon Quantum Dots and Their Derivative 3D Porous Carbon Frameworks for Sodium-Ion Batteries with Ultralong Cycle Life

Adv Mater. 2015 Dec 16;27(47):7861-6. doi: 10.1002/adma.201503816. Epub 2015 Oct 27.

Abstract

A new methodology for the synthesis of carbon quantum dots (CQDs) for large production is proposed. The as-obtained CQDs can be transformed into 3D porous carbon frameworks exhibiting superb sodium storage properties with ultralong cycle life and ultrahigh rate capability, comparable to state-of-the-art carbon anode materials for sodium-ion batteries.

Keywords: carbon quantum dots; electrochemistry; porous carbon frameworks; sodium-ion batteries.
