There is no reason why we shouldn’t be able to drive 1,000 miles in an electric vehicle. ‘Range anxiety’ is holding us back. The material that Capacitor Sciences has developed has the potential to power electric vehicles, utility-scale energy storage.

Capacitor Sciences is developing patent-pending materials to create nano-structured crystalline thin films, that when used as the dielectric material in a capacitor, will be able to create high performance capacitive energy storage cells capable of surpassing energy density and power density of lithium ion batteries, at a significantly reduced cost per kWh. In addition, these capacitive energy storage cells will be non-flammable and safe to operate offering a significant benefit over that of lithium ion batteries.

Pavel Lazarev, PhD, founded Capacitor Sciences and is one of the leaders in the field of molecular engineering of functional nano-structures. Dr. Lazarev saw an opportunity to modify nano-molecular structures he previously used to create optical polarizers, and create a high performing dielectric material to safely and economically store energy.

New CEO leads Company through R&D
Capacitor Sciences hired David de Weese as its chief executive officer to take the Company from dielectric materials development to capacitor prototype performance testing. De Weese, also a general partner at Paul Capital, has held executive positions at life sciences, pharmaceutical and technology companies in the U.S. and in Europe, including Cygnus Therapeutic and Siga Technologies.

“There are dozens of companies enhancing capabilities of lithium ion batteries because it’s the industry- standard storage device,” de Weese said. “But lithium ion batteries are expensive, flammable and slow to charge and discharge. Capacitor Sciences is looking for a better way to increase the energy and power density with safer and economically viable energy storage devices.

“There is no reason why we shouldn’t be able to drive 1,000 miles in an electric vehicle. ‘Range anxiety’ is holding us back. The material that Capacitor Sciences has developed has the potential to power electric vehicles as well as to provide residential, commercial and utility-scale energy storage.”

Capacitor Sciences has also recuited energy storage industry leaders to its board, including David Erhart, Vice President of Engineering for energy storage company Stem, David Schramm, former CEO of Maxwell Technologies and Alan True, founder and CEO of True Family Enterprises and True Innovations.

Dr. Lazarev invents new dielectric materials for high performance capacitors
Dr. Lazarev brings a background in nano-technology research and molecular engineering to Capacitor Sciences. He has now developed the molecular-level composite materials for use in high performance, low cost energy storage cells.

Prior to starting Capacitor Sciences, Dr. Lazarev founded Nanotechnology-MDT which developed atomic force microscopes (AFM), followed by Optiva where he developed E-type polarizers. He also founded Crysoptix which developed optical retarders and Cryscade which developed donor-bridge-acceptor systems for high performance solar PV cells.

Capacitors to achieve high energy density and high power density
Standard film capacitors are limited by low capacitance and ultracapacitors are limited by low voltage. Capacitor Sciences has been able to create composite crystalline dielectric materials that combine high permittivity (high energy density), high resistivity (energy storage longevity) and high breakdown voltage (high energy density). The Company’s technology has the potential to significantly reduce the cost and increase the performance and safety of energy storage devices for all applications including electric cars, buses, homes, businesses, utility grids and other critical operations.
