Abstract
The disclosed technology generally relates to energy storage devices, and more particularly to energy storage devices comprising frustules. According to an aspect, a supercapacitor comprises a pair of electrodes and an electrolyte, wherein at least one of the electrodes comprises a plurality of frustules having formed thereon a surface active material. The surface active material can include nanostructures. The surface active material can include one or more of a zinc oxide, a manganese oxide and a carbon nanotube.
Claims19
A method of forming a separator for an energy storage device, the method comprising:
- printing a film with a mixture comprising a thermally conductive additive;
- and
- drying the film by applying a near infrared (NIR) radiation to the film to cause heating of the film to form the separator,
- wherein the thermally conductive additive is substantially NIR-absorbing to accelerate the heating and thermally conducting while being substantially electrically insulating.
A method of fabricating a supercapacitor, the method comprising:
- forming a first electrode;
- printing a separator film over the first electrode with a mixture comprising a thermally conductive additive;
- drying the separator film with a near infrared (NIR) radiation;
- and
- forming a second electrode over the separator film,
- wherein the thermally conductive additive is substantially NIR-absorbing to accelerate heating of the separator film and thermally conducting while being substantially electrically insulating.
