You know what problem you are trying to solve; we can help you find the right solution!
Working With NOVOCARBON
Every now and then a new customer shows up knowing exactly which product they need. More often, customers come to us looking for help with a problem they are trying to solve. Our job is to understand your particular challenges or requirements and then work with you to identify or develop the right product solution.
The collaborative mindset we employ with our customers extends to our partners and other constituencies. This approach, coupled with deep technical capabilities and an extensive network enables customers who work with NovoCarbon to connect to a business ecosystem with considerable breadth and depth.
Our materials characterization and analysis capabilities described below enable NovoCarbon to understand the composition and behavior of material at a nano scale. It is necessary to work on that level as applications today are pushing boundaries to squeeze maximum performance out of every molecule.
“Brunauer–Emmett–Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of materials.” Source: Wikipedia
Surface area is a key determinant of performance for battery anode materials, because it is on that surface that the useful chemical reactions created by a battery occur. So higher surface area, per a given amount amount of material, is a desirable characteristic for battery materials.
In the case of graphite, porosity and surface area are directly correlated. A higher number of micropores correlates to a higher surface area, as the pores create more surface area by definition. This is the reason why analyzing pore size distribution as well as surface area is used to confirm suitability of material for applications that require robust electrochemical performance.
HP2 – A PROPRIETARY METHOD FOR POROSITY AND HYDROPHOBIC/HYDROPHILIC ANALYSIS
NovoCarbon’s HP2 analysis uses a proprietary, non-destructive method, developed by Dr. Gershon Borovsky, that provides data on structural characteristics of porous material and also the proportion of hydrophobic and hydrophilic material within a sample. Understanding and having the ability to measure these characteristics enables the potential of ensuring that the right material is being provided for applications that are sensitive to them.
PARTICLE SIZE DISTRIBUTION ANALYSIS
Particle size analysis, particle size measurement, or simply particle sizing is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.
The particle size measuremnt is typically achieved by means of devices called Particle Size Analyzers (PSA) which are based on different technologies, such as high definition image processing, analysis of Brownian motion, gravitational settling of the particle and light scattering (Rayleigh and Mie scattering) of the particles.” Source: Wikipedia
NovoCarbon is focused on developing and employing practices to consistently and precisely manufacture products to customer specifications. Particle size distribution analysis is critical to understanding characteristics of a material, or insuring that products are being manufactured with the specified size characteristics.
VISUAL ANALYSIS – SCANNING ELECTRON MICROSCOPY
Scanning electron microscopy (SEM) has been used for decades for particle analysis and to generate very-high-resolution images. NovoCarbon uses SEM imaging services to analyze particles for their shape and size, particularly with the spheronized products.
Chief Science Officer Dr. Borovsky earned his Ph.D. in applied electrochemistry from the Institute of Electrochemistry, Academy of Sciences in Moscow and has worked as a professional electrochemist for the past few decades, specializing in the use of carbon materials for energy-related applications.
