Abstract
Provided are an electrode plate and a lithium-ion battery, the electrode plate includes a current collector layer, a semiconductor layer and an alkali metal replenishing layer. The semiconductor layer is disposed on at least one surface of the current collector layer. The alkali metal replenishing layer is a lithium-replenishing agent layer or a sodium-replenishing agent layer. The alkali metal replenishing layer is arranged on a side of the semiconductor layer far away from the current collector layer.
Claims20
An electrode plate, comprising:
- a current collector layer;
- a semiconductor layer, wherein the semiconductor layer is disposed on at least one surface of the current collector layer;
- and
- an alkali metal replenishing layer, wherein the alkali metal replenishing layer is a lithium-replenishing agent layer or a sodium-replenishing agent layer, and the alkali metal replenishing layer is arranged on a surface of the semiconductor layer opposed to the surface of the semiconductor that is in contact with the current collector layer,
- wherein the semiconductor layer is a thermo-sensitive semiconductor obtained from one or a plurality of oxides selected from ZnO, CuO, NiO, Al2O3, Fe2O3, Mn3O4, and Co3O4,
- wherein the semiconductor layer exhibits a higher electrical resistance at a lower temperature than at a higher temperature.
