CATHODIC ACTIVE MATERIAL ON THE BASIS OF LITHIATED IRON PHOSPHATE WITH A MODIFYING MANGANESE ADDITIVE

摘要

The invention relates to electrical engineering and can be used for the production of a cathodic active material in lithium-ion accumulators and batteries on the basis thereof, which are intended in particular for supplying power for electric transport and for a power tool, and for devices supplying power continuously under load conditions of high power consumption. The proposed cathodic material has the composition LiFe/.JVIntPCVC, where 0.01 < x < 0.6. The modification of lithiated iron phosphate by partial substitution of the iron with manganese makes it possible to increase the internal conductivity and discharge capacity of the cathodic active material, and also to increase the voltage and specific power of the accumulator, owing to which the capacitive and power-generating characteristics of the lithium-ion accumulators containing cathodic material on the basis of LiFeP04 are enhanced, which is the technical result of the invention.
