Capacitor Technology

Hybrid Supercapacitor Battery

We are currently conducting research and development on hybrid supercapacitor batteries. A hybrid supercapacitor battery combines both a supercapacitor and battery (e.g. LiFePO4 battery, or other Li-Ion batteries). By combining both a supercapacitor with a battery, a significantly high discharge current can be achieved for delivery to pulse loads while at the same time extending battery life. 

With sufficient time between each pulse load, the battery will be able to charge the supercapacitor which would handle the high discharge current into a load. This allows the overall efficiency of the system to be improved, because the battery is not subject to the rate capacity effect. Compared to a battery only system, a hybrid supercapacitor battery would allow for smaller batteries to be used in order to achieve the same energy output as larger units.  

High Energy Density, High-Temperature Capable Multilayer Ceramic Capacitors

We are currently engaged in research and development into multilayer ceramic capacitors (MLCCs) for a cost-effective and scalable commercial product and the development of nanocomposite dielectric materials through a synthesizing process highly compatible with conventional ceramic technology. Our ongoing research into new and inexpensive high temperature stable, high energy density dielectric materials is expected to result in the creation of power capacitors.  These devices can be used as a suitable replacement technology for those currently used in power conditioning and pulse power-based systems by providing enhanced performance at higher working temperatures (> 160 °C or more).

Pure ceramic capacitors, in particular multilayer ceramic capacitors (MLCCs), have intrinsically high temperature capabilities. Recent progress in both dielectric materials and related processing allows for the production of the correct type of ceramics which previously have not been employed in large scale productions. This further enables the development and fabrication of high temperature and high energy density power capacitors in a cost-effective and scalable manner.
