Multi-layered coated electrode for lithium-ion battery
Abstract:
Systems and methods are provided for an electrode for a lithium-ion battery cell. In one example, the electrode may include a current collector having two opposing sides, at least one of the two opposing sides being configured with a first coating layer disposed on the current collector at a first loading, where the first coating layer may include a first binder in a first weight ratio, and a second coating layer disposed on the first coating layer at a second loading, where the second coating layer may include a second binder in a second weight ratio, wherein the first weight ratio may be greater than the second weight ratio, and a ratio of the first loading to the second loading may be less than 1:2. In this way, direct current internal resistance of the lithium-ion battery cell may be decreased while maintaining or increasing adhesion within the electrode.
