Abstract
A lithium-ion battery includes a cathode comprising a lithium compound and the cathode further includes solid additives based on metal nitrides and/or borates. The solid additives improve the capacity retention of the lithium-ion battery and extend the battery lifetime. The solid additives also reduce the growth in internal resistance of the lithium-ion battery that is known to occur as Li-ion batteries age. The solid additives help stabilize the lithium-ion chemistry to high cell potentials or temperatures.
