Abstract
A rechargeable energy-storage device includes an anode; a cathode; a structural hydrogel disposed between the anode and the cathode, the structural hydrogel having hydrophilic segments and hydrophobic segments; and a porous carbon material disposed between the anode and the cathode. The hydrophilic segments and hydrophobic segments are uniformly distributed within the structural hydrogel.
Claims20
A rechargeable energy-storage device comprising:
- an anode;
- a cathode;
- a structural hydrogel disposed between the anode and the cathode, the structural hydrogel having hydrophilic segments and hydrophobic segments;

- a porous carbon material disposed between the anode and the cathode.
2 more elements
A method of manufacturing a rechargeable energy-storage device, the method comprising:
- placing an anode material to form at least a portion of a first layer in a container;
- adding a gelled structural hydrogel to form at least a second layer in the container, the gelled structural hydrogel in physical contact with the anode material, the gelled structural hydrogel having hydrophilic segments and hydrophobic segments;
- adding a porous carbon material to the container to form at least a portion of a third layer in the container, the second layer between the first and third layers;
- pushing the porous carbon material toward the anode material such that the porous carbon material is located between the anode material and a volume of the gelled structural hydrogel;
- adding a cathode material to the container on the volume of the gelled structural hydrogel;
- and
- coagulating the gelled structural hydrogel to form a solid structural hydrogel.
