Abstract
An architected transitional metal dichalcogenides, TMD, foam includes plural layers of TMD arranged on top of each other along a given first direction Z, each layer including plural cells, each cell being defined by one or more struts made of the TMD; plural channels extending along a given second direction M, which makes an angle α with the first given direction Z; and plural pores formed on sides of the plural channels.
Claims20
An architected transitional metal dichalcogenides, TMD, foam comprising:
- plural layers of TMD arranged on top of each other along a given first direction Z;
- each layer including plural cells;
- each cell being defined by one or more struts made of the TMD;
- plural channels extending along a given second direction M, which makes an angle α with the first given direction Z;
- and
- plural pores formed on sides of the plural channels.
A battery for producing electrical energy, the battery comprising:
- an anode including an architected transitional metal dichalcogenides, TMD, foam;
- a cathode;
- a separating membrane that separates the anode from the cathode;
- and
- an electrolyte,
- wherein the architected TMD foam includes plural channels having nanometer sized internal diameters.
A method for manufacturing an architected transitional metal dichalcogenides, TMD, foam, the method comprising:
- providing bulk TMD;
- chemically exfoliating TMD nanosheets from the bulk TMD to obtain chemically exfoliated ce-TMD;
- spraying with a nozzle the ce-TMD as a jet onto a substrate to form a layer of TMD material with a thickness below a critical thickness;
- applying a voltage between the nozzle and the substrate;
- spraying with the nozzle the ce-TMD as particles onto the layer of TMD material;
- and
- forming plural channels through the layer by dewetting the layer.
