Inventors include Hassinen, Ville; and Frnti, Arto.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A method for controlling atmosphere of a sealable reaction vessel (60) for precipitating particles comprising one or more of Ni, Co, and Mn, the method comprising: feeding in the reaction vessel (60) a mixture of gases comprising oxygen and inert gas present in a ratio; obtaining exhaust gases from the reaction vessel (60), wherein the oxygen content of the mixture of gases (C1) is different from the oxygen content of the exhaust gases (C2); measuring the oxygen content of the exhaust gases (C2) and providing the measured oxygen content as a first input data (MV1); and adjusting the ratio between the oxygen and inert gas of the mixture of gases based on the first input data (MV1). A method for precipitating particles comprising one or more of Ni, Co, and Mn inside a sealable reaction vessel. A system for controlling atmosphere of a sealable reaction vessel (60) for precipitating particles comprising one or more of Ni, Co, and Mn.
