The electron bandstructure for lithium (bcc) was calculated using the program Quantum Espresso (version 6.4.1). The following parameters for the crystal structure were used for the calculation:
Crystal structure: bcc
Lattice constant: 3.435 Å
To avoid stresses on the crystal the optimal lattice constant for the chosen pseudopotential was determined with a vc-relax calculation.
A high number of k-points (64) have been chosen in each direction to get a smooth density of states.
