1. A method of producing binder-coated active battery material agglomerations, comprising:
agitating, within a vessel, a first volume of a binder-solvent solution with a particulate mixture including active battery material particles to generate a first intermediate mixture, wherein the binder-solvent solution has a solubility limit for a mixture of binder material particles within a first solvent solution at a first set of environmental parameters;
subjecting, while retaining the first intermediate mixture within the vessel, the first intermediate mixture to a second set of environmental parameters which reduces the solubility limit and generates a second intermediate mixture;
agitating, while retaining the second intermediate mixture within the vessel, a second volume of the binder-solvent solution with the second intermediate mixture to generate a third intermediate mixture; and
subjecting, while retaining the third intermediate mixture within the vessel, the third intermediate mixture to the second set of environmental parameters to generate a powder mixture of binder-coated active battery material agglomerations, wherein each of the binder-coated active battery material agglomerations includes one or more active battery material particles having at least a partial coating of binder material.
