High Energy Density Ultracapacitor

Dais is in the development stages of a creating a break-through new energy storage device we have dubbed NanoCap™.

The team is lead by Dais’ Chief Technology Officer, Scott Ehrenberg, and capably supported by Liwei Cao, PhD. , and Michele Dao.

Introduction

NanoCap is being designed to be a 21st century high capacity storage medium having its ‘roots’ in the age old electrical capacitor.

A capacitor consists of two electrodes storing an electrical charge separated by a dielectric which is a non-electrically conducting material. Capacitors are used today in many products – most notably your home’s refrigerator.

NanoCap is a capacitor-like device being engineered with a great deal more to offer in terms of storage, charge, voltage, etc. so it is more likely referred to as an ultracapacitor.

What will make NanoCap so different?

First – the difference begins with a key internal component of NanoCap – the dielectric – it is made of a variant of Dais’s nano-structured polymer material and processes.

Second – our engineering goals for NanoCap address six primary challenges of building a 21 st century energy storage medium:

• High Breakdown voltage
• Low Leakage current
• High energy dense structure
• Low equivalent series resistance
• High voltage operation
• Comparative price performance to existing products

What is the difference from a battery to NanoCap?

While a battery stores its energy as a chemical potential, NanoCap’s energy is stored in its electric field created by charge on its electrodes. NanoCap is being designed, as most ultracapacitors, to accept and deliver energy faster and with less energy loss than a battery.

These differences make regular ultracapacitors more efficient and more powerful than batteries.

Yet – in most cases - batteries today still have had the ability to store about 25 times the energy versus a capacitor.

NanoCap is being engineered to provide an unparalleled dielectric having the ability to absorb electric fields.

This means more energy can be stored in a NanoCap device than other batteries, capacitors, or other ultracapacitors.

The best news?

In testing to date by a third party (the R&D arm of an international conglomerate) the Dais team has seen the required high permittivities.

Recalling - permittivity is a measure of a material’s ability to respond to the presence of electric charge and their corresponding electric fields by blocking the transmission of those fields by absorbing them.

Uses for NanoCap

The markets for ultracapacitors include:

• Transportation technology (electric vehicles and hybrid electric vehicles)
• Consumer electronics (laptops, cell phones, pagers, camcorders, and hand-held tools)
• Medical electronics (defibrillators, drug delivery units, and neurological stimulators)
• Utility (low leveling, ‘smart grid’ services)
• Renewable Energy Sources (safely stores wind and solar energy which is not used at the time of collection for later use)
• Military / defense devices (communication devices, unmanned aerial vehicles, spacecraft probes, and missile systems)

Dais has two internationally filed patents pending for NanoCap. The entire program has received strong support within a limited circle of the technical community.

The Future & Questions

In the coming months watch for more news about this exciting energy storage media; we are very excited and proud of the work to date.

We anxiously look to radically alter other key products and industries with NanoCap as we are doing with our water desalination process (NanoClear), our HVAC system (NanoAir), and in the energy recovery ventilator market with our ConsERV product.
