Advanced, high power and energy battery electrode manufactured by co-extrusion printing
View Patent ↗A battery has an anode, a separator adjacent the anode, and a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of materials, one of the materials forming a pore channel.
1. A battery, comprising:
an anode;
a separator adjacent the anode; and
a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of first and second materials, the first material having a lower lithium concentration than the second material, one of the materials forming a pore channel.
2. The battery of claim 1 , further comprising current collectors adjacent to the anode and the cathode opposite the separator.
3. The battery of claim 1 , wherein the pore channel is formed of the first material.
4. The battery of claim 1 , wherein the cathode comprises an active material of either lithium cobalt oxide or lithium nickel cobalt manganese oxide.
5. The battery of claim 1 , wherein the cathode comprises an active material of one of: lithium nickel cobalt aluminum oxide (NCA), lithium manganese oxide (LMO), or lithium iron phosphate (LFeP).
6. The battery of claim 1 , wherein the anode comprises interdigitated stripes of materials, one of the materials forming a pore channel.
