To provide a method of forming a positive electrode active material with high productivity. To provide a manufacturing apparatus capable of forming a positive electrode active material with high productivity. Provided is a method of forming a positive electrode active material including lithium, a transition metal, oxygen, and fluorine. An adhesion preventing step is performed during heating of an object. Examples of the adhesion preventing step include stirring by rotating a furnace during the heating, stirring by vibrating a container containing an object during the heating, and crushing performed between the plurality of heating steps. By these manufacturing methods, a positive electrode active material having favorable distribution of an additive at the surface portion can be formed.

The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source. Catalysts that may be produced using this improved process include but are not limited to catalysts that promote CO hydrogenation, reforming catalysts, Fischer Tropsch Catalysts, Greyrock GreyCat™ catalysts, catalysts that homologate methanol, catalysts that promote hydrogenation of carbon compounds, and other catalysts used in industry.

A container for storing a powder mixture during heat treatment in a furnace, a furnace and a method for heat treatment of a powder mixture. The aim of the invention is to specify a container by means of which in particular the throughput per unit of time can be increased and an automatic removal of the container is simplified. This aim is achieved by a plurality of receptacles for releasable fastening of spacers which in the installed state allow contactless stacking of a plurality of containers one above the other.

A transport tray for transporting and heating chemical substances, includes a one-piece support structure with a base and a frame fixedly connected thereto, wherein the support structure supports a lining of a tray-shaped cavity for accommodating the chemical substances, wherein the lining includes a base plate lying on the base and multiple frame plates clamped against the frame, wherein the lining is supported by the support structure such that the thermal expansions of the base plate and the frame plates in their plate planes are not impeded.

A heat treatment system disclosed herein may include: one or more saggars, each of which is configured to accommodate powder of a lithium positive electrode material; and a heat treatment furnace configured to heat-treat the powder accommodated in the one or more saggars.
