Abstract
A binder for an electrode is provided herein. In one example, the electrode may include a current collector, and an electrode coating layer, the electrode coating layer including an electrode active material and a binder, where the binder may comprise an aromatic polyamide-based compound, and the binder may be present at greater than 0 wt % and less than or equal to 30 wt % of the electrode coating layer. In one example, the binder provides stronger cohesion between particles of the electrode active material. Methods and systems are further provided for fabricating the electrode including the binder.
