Double current collector cathode design using the same active material in varying formulations for alkali metal or ion electrochemical cells |
摘要 |
A new sandwich cathode design is provided comprising a cathode active material mixed with a binder and a conductive diluent in at least two differing formulations. The formulations are then individually pressed on opposite sides of a current collector, so that both are in direct contact with the current collector. Preferably, the active formulation on the side of the current collector facing the anode is of a lesser percentage of the active material than that on the opposite side of the current collector. Such an exemplary cathode design might look like: SVO (100-x % active)/current collector/SVO (100-y % active)/current collector/SVO (100-x % active), wherein x is greater than y.
