Lithium-metal-oxide composite electrodes
View Patent ↗A composite material having: particles of a first lithium-metal oxide compound, particles of a conductive second lithium-metal oxide compound, a conductive matrix, and a polymeric binder.
1. A composite material comprising:
particles of LiCoO 2 ;
particles of Li 2 RuO 3 ;
a conductive matrix; and
a polymeric binder;
wherein the weight ratio of LiCoO 2 to Li 2 RuO 3 is from about 60:40 to about 55:45;
wherein the particles of LiCoO 2 are free of Li 2 RuO 3 ; and
wherein the particles of Li 2 RuO 3 are free of LiCoO 2 .
2. The composite material of claim 1 , wherein the conductive matrix is carbon black.
3. The composite material of claim 1 , wherein the polymeric binder is polyvinylidene fluoride.
4. An electrode comprising the composite material of claim 1 .
5. A battery comprising:
a cathode comprising the composite material of claim 1 ;
an anode; and
a lithium ion permeable separator between the cathode and the anode.
6. A method of powering a device comprising:
providing the battery of claim 5 ; and
connecting a load to the anode and the cathode.
