Coralloid carbon material based on biomass as a promising anode material for lithium and sodium storage

Abstract

Lithium ion battery (LIB), advantageous in high specific capacity, long cycling life and eco-friendly, has been widely used in many fields. The dwindling reserves, however, limit the further development. Sharing...

One-pot synthesis of biomass-derived porous carbons for multipurpose energy applications

“…Porous carbon materials have been widely used in ion batteries, owing to their high aspect ratio, excellent conductivity, high specic surface area, and good mechanical properties. 153,154 To date, a number of studies have been carried out on one-pot carbonization and activation of biomass to porous carbon anode materials for LIBs [155][156][157][158][162][163][164] and SIBs. 162,[165][166][167] Yang et al 155 prepared N/O self-doped 3D cagelike porous structures and 2D porous carbon nanosheets by one-pot carbonization and K 2 CO 3 activation of peanut oil residues at different temperatures (Fig.…”

Scalable production of reduced graphene oxide via biowaste valorisation: an efficient oxygen reduction reaction towards metal-free electrocatalysis

“…[42][43][44] In recent years, emphasis has been placed on graphene synthesis from various bio-precursors due to economic viability. 27,[45][46][47][48] For a variety of compelling reasons, biomass-derived graphene is proliferating. There are several motivations to employ biomass materials having high carbon content, along with the inherent porosity in graphene structures, which makes it easier for an electrolyte solution to penetrate and thus reduce the ion diffusion distance.…”

Recent Advances in Biomass-Derived Carbon Materials for Sodium-Ion Energy Storage Devices

“…Reasonable utilization of biomass will realize “turning waste into treasure”. Most importantly, biomasses have their unique microstructures and compositions, and the resultant biomass-derived carbons usually retain the diversity of their structures and compositions after pyrolysis ( Figure 1 ) [ 31 , 32 , 33 , 34 , 35 ]. Different structures (e.g., hard carbons, soft carbons, and hybrid carbons), different compositions (e.g., N-doped carbons and other atom doped carbons), and different morphologies (e.g., 1D, 2D and 3D hierarchical structures) of biomass-derived carbons greatly affect their electrochemical performance in SESDs.…”
