Does NB doping affect lithium ion battery performance?
Density functional theory calculations were performed to investigate the effect of Nb doping on the performance of TiO 2 as the anode material of lithium ion batteries using the same computational methodology and scale-similar models for three TiO 2 polymorphs: anatase, rutile, and TiO 2 (B).
How to develop a doping strategy for layered cathode batteries?
Using low-cost, abundant reserve elements for doping modification should be the main direction of future doping strategy development. Technical optimization: at present, the batteries with doping modification of layered cathode materials are still on the laboratory scale.
How do you calculate doping formation energy?
Doping formation energy is achieved by calculating the difference in the energy of the system under study before and after doping, which can be calculated using the following equation: Here, Etotal is the whole energy after the doping process and Epure is the total energy the undoped system.
Does La doping improve the structural stability of cathode materials?
On the other hand, Tang et al. suggested that the La doping contributed to the improved structural stability of the cathode materials and the effective prevention of surficial Li 2 MnO 3 from the erosion of the cathode materials .
Can elemental doping improve layered cathode performance?
Through summarizing previous work about the layered cathode, we found elemental doping strategy can help improve the performance of the cathode in both intrinsic and extrinsic ways with respect to the crystal lattice, electronic structure, nanomorphology, and surface stability.
Does NB-doping enhance lithium intercalation?
For all three investigated polymorphs: anatase, rutile, and TiO 2 (B), Nb-doping enhances the lithium intercalation process by lowering the intercalation energy, but slightly increasing the energy barrier of lithium diffusion due to stronger interaction between the intercalated lithium and polaron induced by Nb dopant in TiO 2.
