The demand for energy production and storage is a worldwide struggle involving specific key challenges. One main challenge is the increasing demand for zero-emission vehicles and portable electronic devices requiring high energy, high voltage systems. Another is the need for an integrated electronic grid that can assimilate discontinuous renewable energy sources. This second challenge which to date has not been addressed sufficiently, can substantially improve overall efficiencies in the renewable energy market. Unfortunately, in order to achieve this state, an economical and environmentally friendly power storage system deployable on a massive scale is required. To date, nothing is able to meet this need as such a technology would require a battery system that employs materials that are abundant and easily accessible.
The battery system that comes the closest to meeting these requirements is the sodium ion battery. However, this technology is immature and suffers from a variety of instabilities and lower energy capacities as compared to lithium ion systems.
We believe with our proprietary composite system, we can fabricate a novel active electrode that can overcome the various instabilities as well as improve the energy and power capacities of sodium ion batteries.
We developed a proprietary composite system with exceptional thermal and chemical stabilities, low CTE (preliminary evaluation), and with mechanically strong and tough properties. We propose to adapt this system to a new process that will render a 3 dimensional highly porous skeletal structure with a tremendously high active surface area. We believe we can achieve this by dispersing throughout the base matrix anodic/cathodic active material and carbon nanoparticles of specific relative sizes. Through a novel process, this loaded composite is then rendered into a 3 dimensional skeleton. We believe this will provide for an abundance of sodium intercalation sites ultimately resulting in much higher energy capacities. And due to the properties of the composite structure, we believe we can overcome the degradation that typically occurs with sodium intercalation and deintercalation in current sodium ion battery electrodes.
Our composite system is very economical, easily and quickly fabricated, with the raw ingredients available off the shelf and in great abundance.
