POSITIVE ELECTRODE MATERIAL FOR LITHIUM RECHARGEABLE BATTERIES Russian patent published in 2019 - IPC H01M4/36 H01M4/04 

FIELD: chemistry.

SUBSTANCE: invention relates to material of positive electrode for lithium rechargeable batteries, as well as to method of its manufacturing. According to the invention, positive electrode material for lithium rechargeable batteries comprises particles of active materials of a positive electrode having a multilayer structure; and at least one conductor selected from a group consisting of a lithium conductor and an electronic conductor, and located on the surface of particles of active materials of the positive electrode. If the material of the positive electrode contains a lithium conductor, the quantitative ratio of the lithium conductor located in planes other than plane (003) of the active material particle of the positive electrode, relative to the total amount of the lithium conductor, is not less than 50 % and not more than 100 %. If the material of the positive electrode contains an electronic conductor, the quantitative ratio of the electronic conductor located in (003) plane of the active material particle of the positive electrode relative to the total amount of the electronic conductor is not less than 50 % and not more than 100 %. Proposed method comprises the steps of: preparing particles of active materials having a multilayer structure and at least one conductor selected from a group consisting of a lithium conductor and an electronic conductor and mixing particles of active materials of the positive electrode and conductor.

EFFECT: technical result is the possibility of reducing the resistance of the lithium rechargeable battery.
