Abstract
A method for manufacturing of a powder mixture for a battery electrode that includes suspending of particles of at least one binder within an inert solvent producing a first suspension, slowly suspending of particles of an active material within the first suspension producing a second suspension, drying of the second suspension producing a granulate material. Further relates to a respective powder mixture, an electrode and a method of manufacturing the electrode.
Claims8
A method for manufacturing of a powder mixture for a battery electrode comprising the following steps:
- suspending of particles of at least one binder within an inert solvent in producing a first suspension wherein the at least one binder is not soluble or is very weakly soluble within the inert solvent;
- slowly suspending of particles of an active material within said first suspension in producing a second suspension wherein the inert solvent is chemically inert with respect to the active material;
- drying of said second suspension in producing a dry granulate material that is dry, free flowing and comprises a weak affinity to agglomeration wherein said at least one binder and said active material are configured to adhere during application of pressure when forming a battery electrode and wherein said inert solvent is not present during said application of pressure when forming said battery electrode.
