ASAC (AdvEn Super Activated Carbon)

High Performance Energy Storage Materials







Proprietary Synergistic Activation

AdvEn’s proprietary recipe and simplified process can achieve a “synergistic activation” effect that substantially increase the performance of activated carbons.  Such an enhancement is not seen in other commercial processes, even with the use of strong acids/bases.  All chemical agents in our processes are readily available and economical.  The synergistic effect enables activation at a lower temperature and eliminates the necessity to use strong acids/bases in the production process.






Feedstock Agnostic

ASAC technology is feedstock agnostic.  It can be applied to various feedstocks containing non-graphitic carbons, whereas most “high performance” activated carbon producers mainly use coconut shell powder which has a low carbon yield.  ASAC technology considers various agricultural wastes and industrial/hydrocarbon wastes and by-products as feedstock; and our finished products offer superior performance to those made from coconut shell powder.

Oil sand by-products are abundant in our home base, Alberta, Canada; not only these feedstocks meet the requirements for high-performance activated carbons produced via our ASAC technology, but also provide carbon yield that is 4 times higher than the commonly used coconut shell feedstocks, due to the higher carbon content and greater chemical stability.  The unique feature of utilizing multiple types of feedstock makes ASAC a material platform technology that converts many streams of wastes into high value-added activated carbon products.

Game Changing Performance

AdvEn’s ASAC technology can produce high performance activated carbons with surface area up to 3,200 m2/g, pore volume up to 1.9 cc/g and metallic impurity content as low as 50 ppm. These highly impactful properties provide significantly higher performance when ASAC is used in various energy storage systems.

ESAC (Electrode Super Adhesive Coating)

Innovative Electrode Fabrication Process











AdvEn’s proprietary ESAC technology enables 20% faster charging rate and enhanced durability that offers longer cycle life, while consuming less energy in the production process. ESAC technology can be incorporated into pre-existing electrode production lines


Supercapacitor and Its Performance Enhancement via ASAC and ESAC

A supercapacitor is composed of two identical electrodes and a separator dividing the two electrodes. The energy storage capacity of supercapacitors is primarily dependent on the surface areas of electrode materials. As a result, most of the commercial supercapacitor electrodes are made of high performance activated carbons with high surface areas, which account for 80% of an electrode’s weight.

Supercapacitors, featuring with high power (fast charging/discharging in seconds), long cycle life (over 1 million charge/discharge cycles) and reasonable capability of storing energy, have been used in consumer electronics, power grid, start-stop systems for automobiles, and are projected to be heavily used in electric buses, trains and wind turbine generators.























Both AdvEn’s ASAC and ESAC technologies serve as critical components in the supercapacitor eco-system. By working together, they can enhance the performance of a 3,000F cylindrical supercapacitor cells (a universal cell form used in heavy-duty grid/transport applications) by 40% in terms of energy density and 35% in terms of power density.
















Li-S battery

Since Li-ion battery’s debut in 1990, the industry has made impressive strides on bringing down the production cost and improving the energy density, which enabled their market adaptation nowadays. Nevertheless, nearly 30 years of developments and innovations have driven the performances of Li-ion technology close to their theoretical limits.  Today the performance of the best Li-ion batteries in the market (energy density 250 Wh/kg, cost US$250/kWh) still lacks far behind of the commercialization target set by US Department of Energy to compete with fossil fuels (energy density 400 Wh/kg, cost US$100/kWh). Among the nascent technologies that hold the potential to make today’s Li-ion batteries obsolete, one is Li Sulfur battery technology.  It is expected to be one of the earliest disrupters to displace current Li ion batteries in meeting the required performance targets of electric vehicles, grid storages and consumer electronics.















High-performance activated carbons can be used as cathode support to help suppress polysulfide dissolutions and extend battery’s cycle life.  AdvEn’s ASAC-30 is designed for this application. ASAC-30 has been sold to tier one European automotive manufacturer and world-renowned research institutes devoted to lithium sulfur system innovations.
