1-12. (canceled)
An electrode composition for a lithium-ion battery, wherein the electrode composition comprises:
- (A) at least one active electrode material;
- and
- (B) at least one mixture of conductive carbon blacks that comprises at least a first conductive carbon black and a second conductive carbon black, the first conductive carbon black differing from the second conductive carbon black.
A process for the production of an electrode for a lithium-ion battery, comprising:
- adding a first conductive carbon black and a second conductive carbon black to a solution of a binder in a solvent to provide a mixture;
- agitating the mixture to provide a homogeneous electrode coating slurry;
- applying the slurry to a current collector foil to provide an applied slurry;
- and
- drying the applied slurry;
- wherein the first conductive carbon black differs from the second conductive carbon black.
