Conductive Aramid Paper for Energy Storage Devices Preview Description
INTRODUCTION
Full details Contact close
This patent-pending technology involves further development of a revolutionary portable energy devices called paper batteries. Paper batteries are flexible energy storage structures utilizing nanotechnology such as CNT carbon nano tube coatings to make highly flexible batteries that can be used in numerous applications, and the substrate used for this technology is of course paper. One prime example of this technology is the research done by Sanford University. The article “Highly conductive paper for Energy-Storage Devices” by Hu, Choi, Yang, Jeong, Mantia, and Cui describes this technology in greater detail. Other organizations performing paper battery research include: Massachusetts Institute of Technology, Rensselaer Polytechnic Institute, NEC Corporation and the Paper Battery Company.
Unfortunately, cellulosic paper (conventional paper technology) may not be capable of withstanding the high demands and/or high performance criteria often demanded for military and satellite applications. These criteria often include strength, temperature resistance and chemical resistance.
Some of the drawback to conventional cellulosic paper include:
1. Electrical applications typically require temperatures greater than 200 C and should
not be readily combustible. The components in wood pulp and papermaking
additives, like starch used in cellulosic papers degrade at temperatures less than 200
C. Also, in applications with higher flammability standards, paper products are
typically combustible.
2. Conventional cellulosic papers are not dimensionally stable. Depending on
temperature and humidity, the dimensions of the cellulosic paper can change. This
can be a problem in processing the paper into paper batteries or lead to application
failures.
3. The rate or degree of ink, liquid or adhesive penetration is important in paper battery
or energy storage manufacturing, especially if in CNT coating is used. Hence,
controlling the porosity of the paper is critical. Unfortunately, the techniques used to
control porosity may be detrimental to high temperature resistance, flammability or
dimensional stability. In addition, it can make the process of manufacturing more
complicated via the utilization of various coating formulations, filler additions and/or
internal sizing technologies used in conventional papermaking.
NEW TECHNICAL SOLUTION
A very viable solution to circumvent the challenges above is the utilization of aromatic polyamide (aramid) paper technology. There is a patent pending on using aramid paper as a substrate specific paper battery.
Aramid papers are currently used in electrical insulation applications (wire paper, transformers) and honeycomb structures in the aerospace industry. Unlike conventional cellulosic paper or other synthetic wetlaid papers or nonwovens, such as polypropylene, (PET) or glass, properties of aramid papers are well suited for the energy storage. or paper battery applications. The compositions of the aramid papers that can be used include chemistries from the meta-aramid and para-aramid families. Examples of these materials include materials manufactured by DuPont under the trade name Nomex® and Kevlar® for meta-aramid and para-aramid, respectively. Techniques and compositions are described in greater detail in the following US patents: 2988782, 2999788, 3018091, 3756908, 4519873, 4729921, 5314742 and 5223094.
The claims for aramid papers used in energy storage or paper battery applications are:
1. Aramid papers have a higher degradation temperature than cellulosic papers or other synthetic papers. They degrade between 350-500 C, and tend to char on the surface. This is a tremendous benefit for applications were the paper absolutely should not be readily combustible.
2. Unlike cellulosic papers in which the fibers are bonded together primarily by hyd
