“One of the three Nobel Prize winners in chemistry in 2019, J. Goodenough (USA), in 1980, discovered the cathode material for 4 Volt batteries LiCoO2. Nowadays, consumer electronics widely use lithium-ion batteries containing LiCoO2 , for example, in laptop computers, cellular telephones, electric vehicles as well as airplanes and even cosmic technologies. One frequently discussed direction to improve the performance of 4 Volt batteries is the development of a family of 5 Volt cathode materials. We were the first in the world to theoretically predict that also a 5 Volt battery is possible. Namely, by means of a Full Potential Linearized Augmented Plane Wave (FP-LAPW) calculations for Li2 CoMn3 O8 battery cathode material we got the average battery voltage for this material around 5 Volt.”
