abstract = {Transition metal oxides are widely used as cathode
materials in rechargeable Li-ion batteries. Here we test the
performance of the parameter-free DFT+ method for
predicting the structural parameters and electronic
configuration of three materials: , and mixed transition
metal compounds. The obtained lattice parameters and band
gaps are consistent with the more computationally demanding
hybrid functionals and SCAN methods. We emphasize the
importance of using a realistic representation of the
orbitals to obtain the correct occupancy of these states,
which are highly overestimated when the widely used atomic
orbitals are applied as projectors. The applied here
Wannier-type projectors result in correct occupancies,
allowing for a decisive assignment of the oxidation states
of cations and an improved description of the electronic
structure. The applied scheme enhances predictive
capabilities of the DFT+ method for computation of
electrochemically active compounds.},
