Electrochemical Characterization of Phosphorous-doped Soft Carbon using Single Particle for Lithium Battery Anode

A low-cost and one-step synthesis of N-doped monolithic quasi-graphene films with porous carbon frameworks for Li-ion batteries

“…In Figure 4d, six types of typical anodes are listed in the Ragone plot: GPF, graphite, graphene, hard carbon, soft carbon and carbon nanotube. As seen from the plot, our GPF electrode exhibit better overall energy and power densities (the values are provided in Table S2) [30,32,[39][40][41][42][43][44][45][46][47][48][49][50][51]. For example, an energy density of 72.5 W h kg À 1 is achieved at a power of 10.7 kW kg À 1 , which is also competitive to other reported anode materials [52].…”

Peanut shell derived hard carbon as ultralong cycling anodes for lithium and sodium batteries

“…To address this issue, rechargeable sodium ion batteries (NIBs) have recently attracted the researcher's attention due to the low cost, abundant sodium resources [8][9][10][11][12][13]. Because of the similar insertion chemistry of lithium ions and sodium ions, various carbonaceous materials such as graphitic carbon [14][15][16], amorphous carbon (hard carbon [17][18][19][20] and soft carbon [21][22],etc., nanostructured carbon (graphene [23][24] and carbon nanotubes [25][26],etc.) have been widely investigated for NIB applications.…”

Nitrogen Doped Microporous Carbons with Tunable and Selective performances in Supercapacitor and Heterogeneous Catalysis

“…In term of heteroatoms doped carbons, some nonmetallic elementals including N, B, S and P [9][10][11][12], can be employed as dopants to modulate the surface feature, energy band structure to improve the application performances. As an intimate neighbor of C in periodic label, N is the most feasible dopant for the conjugation of its lone-pair electrons with the delocalized system of graphitic carbon network with minimal lattice distortion as a sequence of the rich electrons feature of N and the similar atomic radius to C. As for N doped carbons (NCs), the N forms play vital roles on the electronic structure and surface properties of C-N framework, for instance, pyridinic-and pyrrolic-typed N located at the rim of the C-N network facilitate higher capacitive performance via pseudocapacitance contribution owing to the susceptibility to oxidation [13,14]; whereas the graphitic N by replacing skeletal C is beneficial for a higher conductivity owing to the electron donating nature [15]; additionally, the increased surface polarity because of the electronegativity difference between N and C enhances the hydrophilicity [16,17], which is also vital for higher capacitive performance.…”
