Abstract
Disclosed are a high-temperature capacitive energy storage film having a structure in which graphene fluoride (GF) is sandwiched between aramid nanofibers (ANFs) and a method of manufacturing the same.
Claims9
An energy storage film, comprising:
- a first layer and a second layer comprising aramid nanofibers (ANFs);
- and
- a mid-first layer comprising graphene fluoride (GF) disposed between the first layer and the second layer,
- wherein the energy storage film is a free-standing structure, and
- wherein the aramid nanofibers are cross-linked with a crosslinking agent.
2 more elements
A method of manufacturing an energy storage film, comprising:
- preparing a graphene fluoride suspension comprising graphene fluoride;
- preparing an aramid nanofiber suspension;
- applying the graphene fluoride suspension as a second layer on an aramid nanofiber film made of the aramid nanofiber suspension, wherein the aramid nanofiber film is a first layer;
- and
- casting the aramid nanofiber suspension as a third layer on the graphene fluoride and performing drying of the energy storage film, which is a free-standing energy storage film,
- wherein the aramid nanofiber suspension comprises aramid nanofibers crosslinked with a crosslinking agent.
