A lithium-ion battery generally includes an electrode pair, an electrolyte, and a separator. The electrode pair includes a first electrode and a second electrode, wherein the first electrode and the second electrode are of opposite polarity. The electrolyte is configured to allow movement of ions between the first electrode and the second electrode. The separator is between the first electrode and the second electrode. The first electrode generally includes an active layer and a current collector. The active layer comprises a plurality of composite electrode pellets that are non-hollow and include an active material and a binder material. The active layer is provided on a first side of the current collector. The active layer has an overall porosity of greater than approximately 40%. The overall porosity includes both intra-pellet porosity and inter-pellet porosity. |
