From Jackfruit Rags to Hierarchical Porous N-Doped Carbon: A High-Performance Anode Material for Sodium-Ion Batteries

Abstract

Renewable biomass-derived carbon materials have attracted increasing research attention as promising electrode materials for electrochemical energy storage devices, such as sodium-ion batteries (SIBs), due to their outstanding electrical conductivity, hierarchical porous structure, intrinsic heteroatom doping, and environmental friendliness. Here, we investigate the potential of hierarchical N-doped porous carbon (NPC) derived from jackfruit rags through a facile pyrolysis as an anode material for SIBs. The cycling performance of NPC at 1 A/g for 2000 cycles featured a stable reversible capacity of 122.3 mA•h/g with an outstanding capacity retention of 99.1%. These excellent electrochemical properties can be attributed to the unique structure of NPC; it features hierarchical porosity with abundant carbon edge defects and large specific surface areas. These results illuminate the potential application of jackfruit rags-derived porous carbon in SIBs.

Applications of Lithium-Ion Batteries in Grid-Scale Energy Storage Systems

“…Among these energy storage systems, electric batteries exhibit considerable potential for application to grid-level electrical energy storage because of their attractive features, such as flexible installation, modularization, rapid response, and short construction cycles [9,10]. Generally, when electric batteries are applied to the grid-level energy storage system, battery technologies are required to satisfy complex and large-scale deployment applications to the power grid.…”
