    Abstract: An anode and a lithium ion battery employing the same are provided. The anode includes a lithium-containing layer and a single-ion conductive layer. The single-ion conductive layer includes an inorganic particle, a single-ion conductor polymer, and a binder. The single-ion conductor polymer has a first repeat unit of Formula (I), a second repeat unit of Formula (II), a third repeat unit of Formula (III), and a fourth repeat unit of Formula (IV) wherein R1 is O−M+, SO3−M+, N(SO2F)−M+, N(SO2CF3)−M+, N(SO2CF2CF3)−M+, COO−M+, or PO4−M+; M+ is Li+, Na+, K+, Cs+, or a combination thereof; and R2 is CH3, CH2CH3, or CH2CH2OCH2CH3. In particular, the weight ratio of the inorganic particle to the sum of the single-ion conductor polymer and the binder is from 4:1 to 9:1, and the weight ratio of the binder to the single-ion conductor polymer is from 1:1 to 9:1.

    Abstract: A battery is provided, which includes an anode and a cathode. The anode includes a first current collector and anode active material. The anode active material is lithium metal or lithium alloy. The cathode includes a second current collector and cathode active material. The battery also includes an electrolyte film disposed between the cathode and the anode, and a porous film disposed between the electrolyte film and the anode. The battery includes an anolyte in the porous film between the electrolyte film and the anode, and a catholyte between the electrolyte film and the cathode. The catholyte is different from the anolyte, and the anolyte and the catholyte are separated by the electrolyte film and are not in contact with each other.
