Carbon fibers and methods of producing the same
Methods of forming carbon from cotton cloth and the product thereof are provided. The carbon described herein can be used as a structural component and/or as a conductive additive in various battery applications. The method of manufacturing a carbon comprises providing a cotton cloth and pyrolyzing the cotton cloth to form a carbon.
1. A method of manufacturing carbon cloth comprising:
providing a single cotton cloth as a structural component;
hot pressing the cotton cloth, wherein the cotton cloth consists of a weave, knit, intertwine, or interlace; and
pyrolyzing the hot pressed cotton cloth to form the carbon cloth, wherein the carbon cloth consists of the pyrolyzed cotton cloth retaining the same structure as the provided single cotton cloth.
2. The method of claim 1 , wherein the cotton cloth comprises a thread count of about 1 to about 100 threads/cm.
3. The method of claim 1 , wherein the cotton cloth comprises a density of about 1 to about 10 mg/cm 2 .
4. The method of claim 1 , wherein the carbon cloth comprises a thread count of about 1 to about 100 threads/cm.
5. The method of claim 4 , wherein the carbon cloth comprises a density of about 0.5 to about 10 mg/cm 2 .
6. The method of claim 1 , wherein the pyrolizing the cotton cloth comprises heating the cotton cloth to greater than about 900° C.
7. The carbon cloth formed by the method of claim 1 .
8. The carbon cloth of claim 7 , further comprising a thickness of about 10 to about 100 microns.
9. The carbon cloth of claim 7 , further comprising a density of about 0.5 to about 10 mg/cm 2 .
10. A battery comprising the carbon cloth of claim 7 .
11. The method of claim 1 , wherein the provided cotton cloth is rolled.
12. The method of claim 11 , further comprising unrolling the cotton cloth and feeding the cotton cloth into a machine for processing.
