In Russia, the production of supercapacitors based on electrolytes of NITU "MISiS"

    The most joyful event for a scientist is when his scientific developments reach the stage of industrial production. We want to share our joy: the Russian developer of energy storage and storage systems LLC TEEMP (part of the Renova group of companies) launched the production of highly efficient supercapacitors and modules based on them in Khimki, Moscow Region. Each year, the new enterprise will be able to produce up to 200 thousand supercapacitor cells. Electrolytes for supercapacitors were developed by the National Research Technological University MISiS, one of the key partners of TEEMP.


    Starter starting system based on TEEMP supercapacitors

    Traditional batteries (lead-acid, lithium-ion, etc.), despite all their advantages, have one serious drawback. They are able to accumulate a large amount of energy, but this process takes a long time; accordingly, they are not capable of discharging instantly. Someone has successfully compared the batteries with a bottle with a narrow neck: a lot of water will enter, but to pour or pour out - you have to wait. Meanwhile, in the modern world, batteries that are able to instantly charge and discharge are increasingly required. They are called supercapacitors, and if traditional batteries are compared to bottles, then supercapacitors are glasses. With a relatively smaller capacity, they are able to almost instantly accumulate a large amount of energy and equally quickly give up the accumulated charge. This property of them is actively used, for example, in hybrid cars, because, for example, when braking, the energy spent on acceleration is meaningless - it simply goes into the atmosphere in the form of heat through the heating of pads and discs. Supercapacitors help to preserve it, fortunately, and the life of these two types of devices differs fundamentally: more than a million cycles for supercapacitors and several thousand for batteries.

    Until recently, there was no modern production of supercapacitors in Russia, however, in the beginning of the summer of 2017, the situation changed: TEEMP launched the production of highly efficient supercapacitors and modules based on them in Khimki, Moscow Region.

    “The creation of energy storage systems is one of the global trends that will determine the next technological structure in the near future. That is why the Renova Group of Companies is investing in this area right now. Supercapacitors "TEEMP" and the technology of their production - the development of Russian scientists. The intellectual property of the company is protected by Russian and international patents. The production line of the enterprise is unique - its equipment is manufactured according to our technical conditions, and often, according to the company's own drawings ”, - emphasized the Director for Development of High-Tech Assets of the Renova Group of Companies, Chairman of the Board of Directors of ROTEC JSC Mikhail Lifshits.

    TEEMP products are unique in many respects. Supercapacitor modules of the company successfully operate at temperatures up to -60 ° C. They are characterized by low internal resistance, which means that they are able to provide large pulsed currents. Own design of cells and modules allows to reduce the mass and size of the supercapacitor assembly by 30% compared to similar devices.

    The key partner of TEEMP in the project for the production of Russian supercapacitors is the National Research Technological University MISiS. ” In particular, at the Department of Physical Chemistry of the University, which is headed byDoctor of Chemical Sciences, Professor Mikhail Astakhov , developed an original technology for producing electrode materials from organic fibers.

    The main element of the Russian supercapacitor was the nanocarbon material obtained by the university research team with a unique developed surface structure with a maximum area per unit volume. In scientific slang, such a structure is called “whiskers” or “whiskers”.

    This carbon fiber material from organic fiber has unique properties - high current conductivity, increased specific energy consumption - up to 8 Farads / sq. cm - and low cost of production, which is very important in industrial innovation. In terms of aggregate qualities, the new material successfully competes with graphene and nanotubes, and at times surpasses them in terms of cheapness: a gram of graphene costs about $ 1000, a kilogram of carbon “whiskers” - $ 20. In contrast to two-dimensional graphene, “bakendandy” are three-dimensional nanostructures with a given pore distribution (3D), which provides a unique “capacity” and “compactness” of the material.

    The new material provides more efficient storage and accumulation of braking electricity in electric or hybrid cars with its subsequent use during acceleration. This material can be used in stationary energy, pulsed technology, and even in medicine - for pacemakers, tomographs and x-ray machines.

    A similar material, but with significantly lower specific capacity characteristics was tested on several versions of the E-mobile, and in August 2015 in energy storage devices for urban hybrid buses with a total voltage of about 900 V. The efficiency of the recuperators was confirmed by real sea trials.

    Research on materials for chemical current sources began at the Department of Physical Chemistry of NUST “MISiS” back in 2011, when the developers of the E-mobile turned to scientists with a proposal to develop supercapacitors for the energy recovery system of hybrid cars. One of the problems encountered in the development of the domestic hybrid car turned out to be the high cost of foreign-made supercapacitors, as well as the complexity and high complexity of the assembly of nodes. Later, work in this direction was continued in cooperation with TEEMP LLC.

    The project manager from TEEMP Vladimir Tumanov noted:“Our team has proposed a fundamentally new design ideology and assembly technology for supercapacitor modules, thanks to which the complexity of manufacturing drives has been reduced by almost an order of magnitude. At the Department of Physical Chemistry, NUST “MISiS”, headed by Mikhail Astakhov, at the same time, no less original technology was proposed for the production of electrode materials from organic fibers. Together, these two ideas allow in the future to reduce the cost of manufacturing an energy storage device by almost 3 times . "

    The proposed drives can be used in various fields of technology: environmentally friendly personal and public transport, metro, load-lifting construction equipment, elevators, uninterruptible power supply systems and energy quality regulation, as well as in pulse and medical equipment. The developed device of the launch system is capable of operating in stand-alone mode, does not require an electric network and, when charged, it is capable of driving 10 times in a row, for example, a heavy dump truck at temperatures from -40 ° C to -60 ° C. The launch system can be used to launch small aircraft aviation, which require high power in a short period of time, which quickly disables conventional batteries.
