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 Ris OM, SOM, N(SOF)M, N(SOCF)M, N(SOCFCF)M, COOM, or POM; Mis Li, Na, K, Cs, or a combination thereof; and Ris CH, CHCH, or CHCHOCHCH. 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.
