1. A battery, comprising:
a separator that is porous; and
a graphene oxide (GO) nanosheet coating coupled to a surface of the separator, wherein the GO nanosheet coating is configured as a buffer layer to permit transport of Li-ions therethrough and to regulate a rate of flow of the transport of the Li-ions, and
wherein the GO nanosheet coating is lithiophilic.

18. A battery, comprising:
a separator that is porous; and
a graphene oxide (GO) nanosheet coating coupled to a surface of the separator, wherein the GO nanosheet coating is configured as a buffer layer to permit transport of Li-ions therethrough and to regulate a rate of flow of the transport of the Li-ions, and
wherein a plurality of gaps exist between a plurality of GO nanosheets in the GO nanosheet coating and the plurality of GO nanosheets have a plurality of defective sites and have negatively charged functional groups on a surface of the plurality of GO nanosheets that each permit and regulate the transport of Li-ions therethrough.

22. A battery, comprising:
a separator that is porous; and
a graphene oxide (GO) nanosheet coating coupled to a surface of the separator, wherein the GO nanosheet coating is configured as a buffer layer to permit transport of Li-ions therethrough and to regulate a rate of flow of the transport of the Li-ions, and
wherein the surface of the separator that is coupled to the GO nanosheet coating is uneven or bumpy and wherein the GO nanosheet coating is three-dimensional and integrated into the porous separator.
