Zusammenfassung: 
Current lithium-ion batteries are the state-of-the-art power sources for consumer electronics operating mainly in the 4 V regime. One frequently discussed direction to improve the performance of such batteries is the development of a family of 5 V cathode materials. We report here a Full Potential Linearized Augmented Plane Wave (FP-LAPW) calculation for Li2Co1Mn3O8 in the Fd (3) over barm spinel structure. Our calculated battery voltage for this material is around 5 V. This result is stable against interchange of positions of Mn and Co atoms as well as the choice of the position of the Li vacancy.
