Method of preparing a material of a battery cell

A method of producing a material for a battery electrochemical cell, comprising:

• forming a mist of a liquid mixture at desired liquid droplet sizes;
• generating a gas-liquid mixture from the mist and a flow of a first gas inside a first chamber;
• drying the gas-liquid mixture with the flow of the first gas into a first gas-solid mixture inside the first chamber;
• separating the first gas-solid mixture into a first type of solid particles with specific particle sizes and first gaseous mixtures of gases and particles using a first solid-gas separator;
• delivering the first type of solid particles generated from the first solid-gas separator to the first chamber;
• forming a first type of chamber products inside the first chamber;
• separating the first type of chamber products from the first chamber into second type of solid particles and second gaseous mixtures of gases and particles using a second solid-gas separator;
• delivering the second type of solid particles generated from the second solid-gas separator to the first solid-gas separator;
• delivering the second type of solid particles into a second chamber;
• forming a second gas-solid mixture from a flow of a second gas and the second type of solid particles inside the second chamber;
• oxidizing the second gas-solid mixture into an oxidized product and delivering the oxidized product out of the second chamber;
• and
• obtaining a third type of solid particles from the oxidized product.

• drying the gas-liquid mixture with the flow of the first gas into a first gas-solid mixture inside the first chamber;
• separating the first gas-solid mixture into a first type of solid particles with specific particle sizes and first gaseous mixtures of gases and particles using one solid-gas separator;
• delivering the first gaseous mixtures of gases and particles generated from the second solid-gas separator to another solid-gas separator;
• separating the first gaseous mixtures of gases and particles from the another solid-gas separator into second type of solid particles and second gaseous mixtures using the another solid-gas separator;
• delivering the second type of solid particles generated from the another solid-gas separator to the first chamber;
• delivering the first type of solid particles generated from the one solid-gas separator into a second chamber;
• forming a second gas-solid mixture from a flow of a second gas and the first type of solid particles inside the second chamber;
• oxidizing the second gas-solid mixture into an oxidized product and delivering the oxidized product out of the second chamber;
