He represents
Given the increasing demand for energy storage, particularly in advanced technologies like supercapacitors, high-purity and high-efficiency active materials are gaining in importance. Jacobis activated carbon AddSorb Supercap EL is one such specialized product, specifically developed for supercapacitors. In this article, we introduce the company and its AddSorb product line, and then discuss the technical characteristics of Supercap EL, its mechanism of action in supercapacitors, as well as its applications, advantages, and challenges.
Jacobi and the AddSorb series
Jacobi is a leading manufacturer of activated carbon, offering a wide range of products for diverse applications. The AddSorb series includes saturated and purified activated carbon for steam, gas, and electrochemical applications. A highlight of this series is the Supercap EL series – a high-purity, high-capacity activated carbon ideally suited for supercapacitors.
Structure, properties and technical specifications of the EL supercapacitor
For activated carbon to be suitable for use in supercapacitors, it must possess several important properties:
-
Extremely large surface area:
Carbon suitable for supercapacitors has a surface area of thousands of square meters per gram, allowing it to efficiently absorb electrolytes into its pores. -
High-purity impurities and secondary elements with very low levels of impurity can
impair electrochemical performance; therefore, Supercap EL is designed for high purity. -
An optimal pore distribution (micropores, medium pores and large pores)
is crucial for rapid ion transport and the presence of different pore sizes. -
The electrochemical and mechanical stability must withstand multiple charge and discharge cycles .
-
High conductivity enables
efficient charge transfer.
How do supercapacitors work?
Supercapacitors, also called double-layer capacitors, function by storing charge in a double layer between an electrode and an electrolyte. Activated carbon serves as the electrode and provides a large surface area for contact with the electrolyte. Its porous structure allows ions to penetrate quickly and accumulate charge.
The Supercap EL Carbon battery has a large surface area and a large active surface, is able to store charges to a high degree and at high speed , and can go through several charging cycles without noticeable loss of performance.
Application of the EL supercapacitor
Due to its special properties, this activated carbon is widely used in the following areas:
-
Electrodes in supercapacitors
. Main application: as active electrode materials with the ability to quickly charge and discharge. -
Temporary energy storage systems in electronic devices, power tools and regenerative braking systems in electric vehicles. -
Power plants and energy storage systems serve
as emergency power sources for temporary power grids and applications. -
The electrodes of the hybrid supercapacitor battery system combine
the advantages of fast charging of a supercapacitor with the high battery capacity.

Problems and limitations
Despite the many advantages, there are also some problems:
-
High production costs:
The production of high-purity carbon is expensive. -
Strict quality controls mean that
even the smallest impurities can lead to performance losses. -
Stability must be verified under real operating conditions, and
performance must be tested under different temperatures, voltages, and environmental conditions. -
Size limitations and competition from new materials:
Materials such as graphene and nanotubes could become competing materials.
