Dual-template synthesis of novel pomegranate-like hollow carbon nanoparticles with improved electrochemical performance for Li-ion batteries

Carbonization of Carboxylate‐Functionalized Polymers of Intrinsic Microporosity for Water Treatment

“…The Raman spectra of two samples exhibited two broad peaks at about 1345 and 1600 cm −1 . These two bands were attributed to the disordered carbon structure (D‐band) and ordered graphitic structure (G‐band), respectively 32,33. This means that the graphitic carbons with a disordered structure were formed after the decomposition of the main chain.…”

“…These two bands were attributed to the disordered carbon structure (D-band) and ordered graphitic structure (G-band), respectively. [32,33] This means that the graphitic carbons with a disordered structure were formed after the decomposition of the main chain. The relative intensity ratio (I D /I G ) of these two peaks upon further heat treatment at 1100 °C of cPIM-COOH did increase evidently, indicating that the heat treatment caused several structural defects to cPIM-COOH.…”

Doping-template approach of porous-walled graphitic nanocages for superior performance anodes of lithium ion batteries

“…Lithium ion batteries (LIBs) are commercially successful energy storage devices, due to their high energy density, high operating voltage and long cycle life. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Its low cost, good electronic conductivity, moderate operation voltage and stability enable graphite to be the dominant anode material for the current LIBs, leading to many novel anodes prepared from advanced graphitic nanomaterials, such as carbon nanotubes (CNTs), 5,6 nanobers (CNFs), 7 nanocages 2, [9][10][11][12][17][18][19][20] and graphenes, [13][14][15][16]21,22 drawing great attention. However, their performance is still far from satisfactory, especially at a high charge-discharge rate ($0.5 A g À1 ), as graphite has a lower theoretical capacity of 372 mA h g À1 .…”

“…7,10,[12][13][14]20 Additionally, photothermal-reduced graphene was reported to increase Li + diffusion channels by creating micrometerscale open-pore structure in the graphene anodes. 13 Additionally, nanopores was created on the shells of carbon nanomaterials by template approach 3 or KOH activation, 4 which was reported to enhance diffusion of Li + and electrolyte. 3,4 Thus, an efficient method to equably create nanopores on shells of such materials might sharply enhance ions diffusion to improve the performance of the LIBs for high rate applications.…”
