  • Patent number: 12046759
    Abstract: In an embodiment, a Li-ion battery electrode comprises a conductive interlayer arranged between a current collector and an electrode active material layer. The conductive interlayer comprises first conductive additives and a first polymer binder, and the electrode active material layer comprises a plurality of active material particles mixed with a second polymer binder (which may be the same as or different from the first polymer binder) and second conductive additives (which may be the same as or different from the first conductive additives). In a further embodiment, the Li-ion battery electrode may be fabricated via application of successive slurry formulations onto the current collector, with the resultant product then being calendared (or densified).
