Abstract
A catholyte-like material including a cathode material and an interfacial additive layer for providing a lithium ion energy storage device having low impedance is disclosed. The interfacial additive layer, which is composed of vapor deposited iodine, is present between the cathode material and an electrolyte layer of the device. The presence of such an interfacial additive layer increases the ion and electron mobile dependent performances at the cathode material interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device. The catholyte-like material of the present application can be used to provide a lithium ion energy storage device having high charge/discharge rates and/or high capacity.
