Thermodynamics of Lithium Intercalation into Graphites and Disordered Carbons
The temperature dependence of the open-circuit potential of lithium half-cells was measured for electrodes of carbon materials having different amounts of structural disorder. The entropy of lithium intercalation, DS , and enthalpy of intercalation, DH , were determined over a broad range of lithium concentrations. For the disordered carbons, DS is small. For graphite, an initially large DS dec...

Micro-sized porous carbon spheres with ultra-high rate capability for lithium storage.
Biomass-derived carbon materials, as one type of promising anode material for lithium ion batteries (LIBs), have demonstrated intrinsic potential and superiority. Here, we report a facile and efficient approach to fabricate micro-sized porous carbon spheres (PCSs) by an integrated procedure of enzymolysis, pre-oxidation, and carbonization. Benefiting from the uniquely abundant pore accessiblity...
متن کاملGGA+U description of lithium intercalation into anatase TiO2
We have used density-functional theory generalized gradient approximation GGA to study lithium intercalation at low concentration into anatase TiO2. To describe the defect states produced by Li doping a Hubbard “+U” correction is applied to the Ti d states GGA+U . Uncorrected GGA calculations predict LixTiO2 to be metallic with the excess charge distributed over all Ti sites, whereas GGA+U pred...
