Abstract
A method of making electrodes with distributed material loadings used in rechargeable electrochemical cells and batteries is described. This method controls electrode material loading (mass per unit area) along the electrode's length while maintaining uniform compaction throughout the electrode. Such prepared electrode maintain sufficient mechanical flexibility for winding and are compact and robust to have high energy density and long cycle life in rechargeable cells and batteries.
