Quasi-Electrostatic Simulation of Energy Density Limits and Variability in Nanoparticle Composite Materials

Costello B., Davis J.A., Georgia Institute of Technology, US

To understand the limits and opportunities of nanoparti- cle (NP) composite materials, it is imperative to better un- derstand the heterogeneous electric field distributions within such materials. Using a custom-built simulator, the electric field is [...]

Development of Novel Nanocomposite Dielectrics for High Voltage, High Energy Density Multilayer Ceramic Capacitors (MLCCs) Applications.

Tan C., Aegis Technology, Inc, US

There are demanding requirements on multilayer ceramic capacitor (MLCC)-based power capacitors in the development of more advanced electronics and platforms for both civic and military applications. Currently used MLCCs, however, suffer from limitations of low [...]

Electroactive Polymers as Battery Electrodes

Lutkenhaus J.L., Texas A&M University, US

Plastic power, or energy storage platforms primarily consisting of polymers, offers opportunities never before available in current state-of-the-art prismatic or coin cells, such as flexible, structural, or stretchable energy storage. Electroactive polymers, a class of [...]

High energy density and high temperature multilayered polymer film capacitors

Langhe D., Ponting M., PolymerPlus LLC, US

Current state-of-the-art polymer film capacitors have a limited energy density of 2.4 J/cc for pulsed power and energy storage applications, and are based on twenty year old technology and materials. Improving the energy density limit [...]

Manganese Oxide/Carbon Nanofibers-Embedded Graphene Sheets for Capacitors

Ahn K-J, Yoon H., Chonnam National University, KR

We report the fabrication of a ternary nanoarchitecture consisting of manganese oxide (MnO), carbon nanofibers (CNFs), and reduced graphene oxide sheets and their application to supercapacitor electrodes. MnO nanoclusters-decorated CNFs (MCNFs) with diameters of about [...]

Use of Reticle Carbon in Supercapacitors

Nesbitt C.C., Reticle, Inc., US

Supercapacitance is an increasingly growing area of interest for a number of electric, and electronic applications. Storing energy that is readily recovered can extend the life or improve the efficiency of chemical batteries, rapid-pulse batteries [...]

SOS Gate Capacitance Modeling

Morris H.C., Cumberbatch E.C., Abebe H., San Jose State University, US

A gate capacitance model for the SOS structure has been developed. The spatial dependence of the potential defines the changes in the charge density as well as the boundary conditions between the layers. The SOS [...]
