Bipolar lithium ion cathodes and cells and batteries containing lithium ion cathodes

A bipolar lithium ion cathode comprising two different cathode active materials located in two distinct cathode layers on a single current collector,

• wherein:
• i) the two different cathode layers are disposed adjacent to one another, and the current collector is disposed adjacent to one cathode layer only:
• ii) the current collector is disposed adjacent to and between the two different cathode layers;
• iii) the two different cathode layers are both disposed adjacent to the current collector in different regions on a surface of the current collector:
• or
• iv) the cathode comprises two layers each of the distinct cathode layers in which, on one side of the current collector, the two different cathode layers are disposed adjacent to one another and the current collector is disposed adjacent to a first type of cathode layer only and, on an opposite side of the current collector, two different cathode layers are disposed adjacent to cone another and the current collector is disposed adjacent to the first type of cathode layer only;
• and
• wherein the two different cathode active materials are selected from:
• lithium nickel manganese cobalt oxide (NMC) in which nickel (Ni) is present in at least 50 wt % of the total weight of Ni, manganese (Mn), and cobalt (Co):
• lithium nickel cobalt aluminum oxide (NCA):
• lithium nickel manganese cobalt aluminum oxide (NMCA), lithium iron phosphate (LFP), lithium manganese iron phosphate (LMFP), lithium manganese nickel iron phosphate (LMNFP), lithium iron cobalt phosphate (LFCP), lithium iron manganese cobalt phosphate (LFMCP), and any combinations thereof.
