An electrode for a Lithium battery, the electrode comprising:
- a multi-dyad laminate stack formed of multiple ones of a metal oxide layer including one or a combination of metal oxides taken from the group consisting of:
- TiO2, and MnO2,
- wherein the metal oxide layer has a layer thickness ranging between 0.3 and 300 nm;
- wherein a pair of the multiple ones of the metal oxide layer are separated by a decoupling layer;
- and
- wherein the decoupling layer is an electroconductive polymer layer having a thickness ranging between 0.1 and 10 nm.
A method of manufacturing an electrode for a Lithium battery, the method comprising the providing a substrate and repeatedly performing the steps of:
- depositing a titanium oxide, manganese oxide, or a mixture thereof in a first deposition stage, to provide a sheet of titanium oxide, manganese oxide, or a mixture thereof, having a thickness ranging between 3 and 300 nm;
- and
- depositing an electroconductive polymer in a second stage, to provide a monolayer of electroconductive polymer,
- thereby providing a multi-dyad nanolaminate stack formed of nanosheets of titanium oxide, manganese oxide, or a mixture of titanium oxide and manganese oxide.
