Hierarchically porous nitrogen, oxygen-rich carbons derived from filter paper for high-performance lithium ion battery anodes

Multi-stage explosion of lignin: a new horizon for constructing defect-rich carbon towards advanced lithium ion storage

“…37 The edge N-5 and N-6 species can act as active adsorption sites for Li-ion storage. 38 The edge-N doping levels of PLPCC-600, PLPCC-700 and PLPCC-800 are 1.1, 1.3 and 0.5 at%, respectively. Furthermore, the edge-N doping level of PLPCC-700 is higher than that of SLCM (0.4 at%).…”

Facilely synthesized LiFePO4nanocomposites with excellent electrochemical properties as cathodes for lithium ion batteries

“…5c) and eqn (2). [46][47][48] Combined with eqn (1), the D Li + of LFP-0, LFP-5, LFP-10, LFP-15, and LFP-20 can be calculated, and are shown in the following Table 2.…”

“…5c) and eqn (2). 46–48 Combined with eqn (1), the D Li + of LFP-0, LFP-5, LFP-10, LFP-15, and LFP-20 can be calculated, and are shown in the following Table 2. The diffusion coefficient of Li + of LFP-15 is the best (1.43 × 10 −11 cm 2 s −1 ) among them, which can be attributed to the N-doped carbon coated on the surface of LFP providing a good conductive network.…”

Sustainable hydrothermal carbon for advanced electrochemical energy storage

“…1), including supercapacitors 13,46,48,[57][58][59][60][61] and Li-ion batteries. 62,63 Particularly, the enlarged porosity can shorten the pathway for Li + diffusion in the bulk electrode and improve the Li + transportation kinetics, 64 while the functional groups embedded in the carbon skeleton can change the electronic structure and improve the pseudocapacitance of supercapacitors.…”
