Influence of the scandium doping to the properties of high voltage spinel cathode
Original language description
One of the problems which were always associated with accumulators in general is their low voltage. For powering a more demanding application, there is always the need to stack more cells together to obtain a higher voltage. Conventional Li-ion accumulators are charged to 4.2 V maximum and their nominal voltage is 3.6-3.7 V. There have been attempts to produce an accumulator with higher voltage lately. Its charging voltage should be around 5 V and voltage during discharging over 4.5 V. From the group ofhigh voltage cathode materials, the LiNi0.5Mn1.5O4 spinel is the most promising material. Solid state reaction method was chosen as the method of synthesis of this material and as the method of stabilizing the structure by doping by other element - in this case by scandium.
