About

The Science of Storage

EnerG2 and its state-of-the-art scientific approach to energy storage materials has been backed over the past five years by the public and private sectors.  Among the company’s supporters: the University of Washington, the Washington Technology Center, a state-supported economic development agency that finances applications of university research, WRF Capital of Seattle, Washington, the Sustainability Investment Fund of Portland, Oregon, OVP Venture Partners of Kirkland, Washington, and Firelake Capital Management of Palo Alto, California.

In October 2008, EnerG2 raised $8.5 million in Series A financing. The financing was led by OVP and Firelake.

Here are some of the most frequently asked questions about EnerG2:

What does the company do?

EnerG2 engineers advanced nano-structured materials for energy storage breakthroughs.

How important is energy storage to the sustainable economy?

We believe that efficient, reliable and cost-effective clean energy storage will be an essential element of the emerging post-petroleum economy.

What makes EnerG2 different?

EnerG2 approaches the problem with engineered materials solutions; and, from our perspective, it’s the materials that matter in any energy storage device.

Rather than accept the limitations of naturally occurring materials, EnerG2 uses materials science to assemble cutting-edge products at the molecular level. Controlling the molecular structure and assembly process of our engineered materials at the earliest stage possible provides flexibility, lowers costs and maximizes performance. As a result, we are delivering new capabilities and creating fresh opportunities in energy storage.

What is EnerG2 focused on today?

EnerG2 is currently focused on customizing electrode materials to enhance energy and power density in ultracapacitors, one of the essential engines of the new energy economy. Ultracapacitors, which are dependent on the performance of their materials, store and release more energy faster than conventional batteries. The size and make-up of the electrodes’ surface area helps ultracapacitors store and supply large bursts of energy; the materials also effectively enable limitless cycle life.

What are the most promising applications for ultracapacitors?

Ultracapacitors containing EnerG2 materials will be increasingly embraced by the automotive industry for hybrid electric vehicles, by electronics manufacturers for enhancing the life and usability of consumer goods, and by a variety of industrial customers to deliver an ever-increasing breadth of new ways to improve energy efficiency.

What’s next for EnerG2?

In the future, EnerG2 materials may be used to improve natural gas, methane and hydrogen storage as well as lithium-ion batteries.

Technology

The patented and proprietary technology used by EnerG2 is based on nano-structured carbon materials that are finely controlled and offer ultra-high surface areas.  These materials are extremely conductive and are tremendously attractive to energy-storing molecules such as electrolytic ions, methane, natural gas and hydrogen. The result: maximum energy storage that is exceedingly cost effective. Working in collaboration with the University of Washington Department of Materials Science & Engineering, EnerG2 has developed unique sol-gel processing technologies to construct its carbon materials.  Sol-gel processing, which creates optimal structure and purity in the finished carbon product, is a chemical synthesis that gels colloidal suspensions to form solids through heat and catalysts. EnerG2 has invented a patented ability to control the hydrolysis and condensation reactions within the gelling process, and this allows the materials’ surface structures and pore-size distributions to be shaped, molded and customized for a variety of critical energy storage uses. The EnerG2 approach to energy storage material manufacturing is unique.  Most commercially available materials for energy storage are produced from naturally occurring precursors; therefore much of the performance of these derivative materials is determined by natural physical properties of the selected precursor. As a result, important characteristics such as pore-size distribution and purity are fixed within the natural precursor and are merely exposed by competitors’ various processing approaches.  Innovation at EnerG2 is derived from molecular self-assembly; to put it simply, we build our energy storage materials from scratch, and this leads to greater structural control, improved product purity and an ability to escape today’s energy storage performance limitations. EnerG2 has developed these processing capabilities with an explicit and aggressive focus on cost control.  To avoid the expensive processing typically associated with nanotechnology, the company has leveraged large-scale commercial processing technologies from established industries to design a production approach that is both relatively inexpensive and inherently scalable.

EnerG2 focuses its efforts and attention on three core carbon material groups:

  • Granules in infinitely variable carbon particle sizes are used to make high-performance electrode materials for ultracapacitors.

  • Monoliths are the carbon materials composed of the granules in relatively solid form prior to milling and are used in methane and natural gas storage systems.

  • Nano-Composites are created when carbon materials are mixed with chemical and metal hydrides; they are central to hydrogen storage systems.

About

APowerCap Technologies, LLC (APCT) is a company backed by a pioneering Ukrainian venture capital firm TechInvest. Incorporated in the U.S. in 2006, APCT has R&D and production facilities in Kyiv, Ukraine. APCT develops breakthrough ultracapacitor-based power modules for wide range of applications.

APCT technologies will bring new level of efficiency to dozens of verticals, including vehicles (hybrid, PHEV, electro), consumer electronics, telecommunications, energy generation, quality power supply and others.

APowerCap development team has been conducting research in the field of ultracapacitors for more than 17 years. R&D on ultracapacitors began within the framework of a special project of the Ministry of Electronics of the former Soviet Union. After the collapse of the Soviet Union, members of the R&D team established a company, which offered contract R&D services for international clients in ultracapacitor technology. Among its clients were Skeleton Technologies (former SuperFarad), Idaho National Laboratory, Ener1, Inc.

In 2005, ultracapacitor technology project became a finalist of Ukrainian High-Tech Competition, and successfully presented the technology to international VC investors at SVOD Technology conference in Silicon Valley. In 2006, APowerCap Technologies was established and received seed investment from TechInvest.

APCT R&D team has a number of Ukrainian and Russian patents on ultracapacitors technology and ultracapacitor parts, which were transferred to APCT. Based on the know-how accumulated by the R&D team, APCT has filed two US patents.

Ultracapacitor prototypes, developed by APCT, have been tested by leading industry experts, including:

  • ABB Research Center (Sweden, 1996-1997)
  • INEEL (1997-1998)
  • ITS, Davis, CA (1997-2006)

Test results of APCT ultracapacitor prototypes of 55 F, were highly appreciated by participants of the 16th International Seminar on Double Layer Capacitors & Hybrid Energy Storage Devices in 2006. According to Dr. Burke, a recognized expert in ultracapacitors and relative technologies, APCT ultracapacitors have superior performance comparing with other developers. «The RC time constant of the APowerCap cell is significantly lower and its peak power is considerably higher than any ultracapacitor previously tested from other developers», said Andrew Burke.

Tests have demonstrated that APCT has achieved the best results in the world in ultracapacitor performance and is able to achieve best cost advantage.

Technology

Key Features:

  • novel organic electrolytes based on alkylamino phosphonium or alkylammonium salts and polar aprotic solvents
  • low-cost porous carbons as electrode materials and technology for purification of these carbons
  • special technique for electrode/electrolyte preparation together with some peculiarity of SC assembling and pre-starting (aging) procedure
  • novel methods to significantly reduce ultracap inner resistance

Over the past decade or two ultracapacitors force their way to the market through the strong competition from advanced batteries. Today NiMH and in particular Li-ion batteries demonstrate the power density as high as 0.6-1 kW/kg (though at the expense of lower energy density, shorter cycle life and overheating). Therefore, to become competitive, ultracapacitors must demonstrate the power density much higher than 1 kW/kg providing at the same time the long cycle life. The best of our competitors and ultracapacitor manufacturers demonstrate 1-3 kW/kg at 95% efficiency, while our prototypes demonstrate 5-6 kW/kg.

Another obstacle for ultracapacitors on the path to the market is cost of carbon. Nanoporous carbon, which is used as electrode material in supercapacitors, is rather expensive, and it typically contributes about 35% to the total cost. APCT has utilized carbon, which is 4 times cheaper than that used by its major competitors.

APCT middle and large devices can demonstrate the same performance being 2 or 3 times smaller (due to much higher power density), this means that APCT uses 2-3 times less material than competitors.
Currently, APCT research team is focused on achieving the following:

  • to reduce ESR, in particular, to reduce the contact resistance at C/Al interface due to modification of Al current collector
  • to modify some of the natural carbonaceous materials in order to produce low-cost nanoporous carbon electrodes
  • to best match the electrode nanoporous texture with ion size in organic electrolytes
  • to optimize the ratio between nanopores and ion transport channels in the electrode texture
  • to optimize the electrode thickness
  • to protect the Al current collector from anode corrosion
  • to develop special fire retardant agents to assure safety

Products

APowerCap offers ultracapacitors that have been designed using our proprietary breakthrough ultracapacitor technology. This unique technology allowed us to reach values of specific power that exceed 5 kW/kg at a 95% efficiency that corresponds to more than 20 kW/kg at a 50%, keeping the energy density within 1.5-4.5 Wh/kg despite the use of low-cost nanoporous carbon.

Our major goal is to satisfy global market requirements for ultracapacitors in both performance and price. We offer products for prices that at least 20% lower, compared to products with similar voltage/capacitance rates already available on the market.

APowerCap has designed ultracapacitors with outstanding performance that have been recognized by the leading industry experts to be the best in the world in terms of power density. APowerCap ultracapacitors can be used for a wide range of applications, including consumer electronics, power quality systems, automotive industry and many others.
