Abstract:
Electrochemical cells of the present disclosure may include one or more multilayered electrodes. One or both multilayered electrodes may be configured such that a second layer farther from the current collector has a higher resistance to densification than a first layer closer to the current collector. This may be achieved by including a plurality of non-active ceramic particles in the second layer. Accordingly, calendering of the electrode results in a greater compression of the first layer, and a beneficial porosity profile is created. This may improve the ionic conductivity of the electrode, as compared with known systems.
