A composite metal foil and a method of manufacturing the same are provided. The composite metal foil includes at least a first metal layer and a second metal layer. The first metal layer is copper foil, nickel foil, stainless steel foil, or a combination thereof. The second metal layer is disposed on a surface of the first metal layer. A contact angle of a surface of the second metal layer to liquid lithium metal is lower than 90 degrees.

Composite metal foil

A lithium ion battery is provided, which includes a positive electrode, a negative electrode, and an electrolyte disposed between the positive electrode and the negative electrode. The negative electrode includes a current collector and a &#x3b2;-phase-based polyvinylidene fluoride (&#x3b2;-PVDF) layer coating on the current collector. The &#x3b2;-PVDF layer may have a thickness of 1 &#x3bc;m to 10 &#x3bc;m.

Negative electrode and lithium ion battery

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.
