Employees of the NTI Center for New Functional Materials (CNFM) of the NRUDeveloped and registered in Rospatent a program for processing spectra of electrochemical impedance of carbon nanomaterials. The new software, created thanks to financial support from the NTI Fund, significantly accelerates data analysis and helps researchers quickly select promising materials for future industrial applications.
—The program helps to analyze data obtained during testing of various electrically active materials, in particular carbon materials, with a focus on development and research that has recently been done at CNFM., — explained the developer, an employee of CNFMDanil Polski.
According to him, the software allows evaluating not only the resistance of substances to current, but also what occurs at the phase boundary between the electrode and the electrolyte:
—This makes it possible to separate the material’s own properties and process parameters, and to individually assess the contribution of various phenomena to the overall picture.
Carbon nanomaterials, and especially multi-walled carbon nanotubes (MWNTs), are supplied to NGU by the Institute of Catalysis SB RAS as part of a joint grant. The obtained materials are used in Li-ion batteries, supercapacitors, sensors, electrolyzers, as well as in special pastes and coatings. They help create lighter and stronger components, improve conductivity and device durability, and also save energy in various industries—from energy to electronics. Therefore, a precise understanding of the electrochemical properties directly affects the speed of new technology development.
—At NGU from MUNT, they initially manufacture working electrodes, which are then tested in target processes — for example, in the electrochemical generation of hydrogen peroxide, or in the multiple cycling of Li-ion batteries and supercapacitors in order to determine their reliability and durability, — commented the director of CNFM NGUDenis Kozlov.
There are similar programs in the world, but, as developers note, the main issue is convenience.
—Most programs are designed so that their use implies manual data processing mode, whereas our program, on the contrary, is automated. With its help, I can obtain 30–40–50 spectra per day and analyze them in 15–20 minutes, instead of spending 15–20 minutes processing each spectrum., — emphasizedDanil Polski.
In his assessment, the new program performs a series of operations ten times faster than many solutions available on the market.
The work on the program took about three years — from the first template to the current version, which is already used in CNFM on a real object. Now it is a single executable file that can be installed and immediately applied in calculations. The program has not yet been released to open access and is used as a working tool of CNFM; the issue of transfer to external industrial partners will be decided at the Center level.
