High-performance lithium battery driven by hybrid lithium storage mechanism in 3D architectured carbonized eggshell membrane anode

Self‐standing hard carbon anode derived from hyper‐linked nanocellulose with high cycling stability for lithium‐ion batteries

“…[1][2][3][4][5][6][7][8][9] Among them, graphite has been investigated firstly and commercialized successfully as anode materials for LIBs owing to its relatively stable electrochemical properties and low working potential. [10][11][12][13] However, the limited theoretical capacity of 372 mAh g −1 and poor rate capability of graphite-based anode are unable to satisfy the increasing demand for future high-energy storage applications. [14][15][16][17][18][19][20] To address the aforementioned problems, intense effort has been made to pursue higher capacities of other carbonaceous anode materials.…”

“…27,28 According to the different precursors, hard carbon can be divided into resin-based hard carbon, 29,30 pitch-based hard carbon [31][32][33] and biomass-based hard carbon. 12,[34][35][36] Among them, biomass-derived hard carbon represents great advantages in terms of precise nature-made structure, sustainable carbon sources, low cost as well as large-scale production. [37][38][39][40] Up to now, corn stalks, 41 coffee grounds, 42 lignin, 43 egg white, 44 wheat flour 39 and other biomass materials have been applied as potential precursors to prepare carbon anode materials in achieving desirable performance LIBs.…”

“…Carbonaceous materials, as a vital family of anode materials for lithium‐ion batteries (LIBs), are receiving considerable attention due to their low cost, large abundance, tunable electronic and structural properties 1‐9 . Among them, graphite has been investigated firstly and commercialized successfully as anode materials for LIBs owing to its relatively stable electrochemical properties and low working potential 10‐13 . However, the limited theoretical capacity of 372 mAh g −1 and poor rate capability of graphite‐based anode are unable to satisfy the increasing demand for future high‐energy storage applications 14‐20 .…”

“…The microstructure and performances of the final hard carbon materials depend strongly on the nature of the precursor 27,28 . According to the different precursors, hard carbon can be divided into resin‐based hard carbon, 29,30 pitch‐based hard carbon 31‐33 and biomass‐based hard carbon 12,34‐36 . Among them, biomass‐derived hard carbon represents great advantages in terms of precise nature‐made structure, sustainable carbon sources, low cost as well as large‐scale production 37‐40 .…”

Graphitic Nanocup Architectures for Advanced Nanotechnology Applications

“…For decades, diverse graphitic nanostructures (e.g., nanographite, carbon nanotubes, carbyne, and graphene) have been actively researched for applications in energy storage devices, bio/chemical sensors, drug delivery, etc. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. While significant progress has been made on both developing large-scale synthesis and unveiling their exceptional properties, there remain challenges in controlling morphology and proportion of individual nanoscale units, which limits their use in down-to-earth applications [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”
