Abstract

An electrode material for a secondary battery and a secondary battery are provided. The electrode material for the secondary battery includes tin-manganese-nickel-oxide. The secondary battery includes a cathode, an anode, an electrolyte, and a package structure, wherein the anode includes the electrode material for the secondary battery.

First claim

What is claimed is:

1. An anode material for a secondary battery, comprising:
a tin-manganese-nickel (Sn—Mn—Ni)-oxide represented by formula (1) below,
Sn x Mn y Ni z O w   (1),

wherein 0.1≤x≤0.9, 0.1≤y≤0.9, 0.1≤z≤0.9, and (x+y+z)/2<w<(x+y+z)×3.

2. The anode material for the secondary battery of claim 1 , wherein the Sn—Mn—Ni-oxide is a monocrystalline, microcrystalline, polycrystalline, or amorphous material.

3. The anode material for the secondary battery of claim 1 , wherein the anode material for the secondary battery is single-phase or multi-phase.

4. The anode material for the secondary battery of claim 1 , wherein the anode material for the secondary battery further comprises a binary metal oxide formed by an oxygen element and one of Mn, Ni, and Sn elements, a ternary metal oxide formed by an oxygen element and two of Mn, Ni, and Sn elements, or a combination thereof.

5. A secondary battery, comprising:
a cathode;
an anode separately disposed from the cathode, and the anode comprises the anode material for the secondary battery in claim 1 ;
an electrolyte disposed between the cathode and the anode; and
a package structure covering the anode, the cathode, and the electrolyte.

6. The secondary battery of claim 5 , further comprising a separator disposed between the anode and the cathode, the separator, the anode, and the cathode define a housing region, and the electrolyte is disposed in the housing region.
