Lithium ion batteries store and supply electrical energy in mobile telephones, laptops and tools. Mobile applications, such as electric bicycles, electric scooters and other electric vehicles and hybrid concepts are also creating a steadily rising demand for batteries.

The goal is to develop ever more powerful batteries that feature increased capacity, a longer lifetime, shorter charging times and lighter weight. Lithium ion batteries are basically comprised of a negative electrode (anode), a positive electrode (cathode) and a separator membrane. The individual electrodes are made up of conductor foils that are coated with a mixture of binders, active materials and additives (battery slurries).

In addition to the mechanical and thermal resistance of the separators, the key factors for the quality and safety of the batteries are the chemical composition, the shape and particle size distribution of the active materials, the homogeneity and the absence of defects in the coatings on the conductor foils of the electrodes. Based on many years of experience, NETZSCH offers an extensive portfolio of machines and equipment for dry and wet grinding, mixing, homogenization, dispersion, delamination, separation and deaeration, as well as analysis.


Paper is certainly the first thing that comes to mind for most people when they think of cellulose. Of course that is correct, but it is only a fraction of the actual range of applications for this material. This natural product has many varied uses in today’s society – both in its pure form or as a so-called derivative (i.e. a chemically-altered substance with a cellulose base). From a chemical standpoint, cellulose is a polysaccharide; i.e. a cellulose molecule has been assembled into a long chain from many sugar building blocks (specifically: glucose).

Through chemical transformation of the raw cellulose, many additional properties can be attained. Overall, the extraction of cellulose is a complex procedure. An entire series of mechanical and chemical steps are required, first to separate cellulose from the associated natural materials and then to refine it until chemically pure.

Ceramics / Glass

Ceramic materials have been used since the early history of mankind. The first figures were formed from ceramic materials and hardened by baking over 24,000 years ago. Other discoveries prove the manufacture of bricks (approx. 14,000 years ago) or the production of practical ceramic vessels (7,000 to 8,000 years ago).
To this day, ceramics have proven their worth in a multitude of applications. Continuous development means that ceramics are also of interest for new applications which require strength, wear resistance, corrosion resistance and temperature stability – and, at the same time, a low specific density.

Ceramic materials are components of plants for metallurgy, chemistry and energy production. Due to their great strength and wear resistance they are used as metal-working tools. The automotive industry uses them, for example, as sparkplug insulators, rocker arm coatings, port liners in the hot area of the exhaust manifold and lightweight valves in the motor. Their electrically insulating, magnetic, dielectric, semiconducting, superconducting properties are used for the production of functional ceramics in the electrical industry.
The mechanical and physical characteristics of ceramic materials can be manipulated by, among other things, selective adjustment of the microstructure.

Digital Inks

Look around you and for sure you will find an object that has been printed with inkjet technology.

For years, the ceramic industry has used digital printing to decorate tiles using pigmented ceramic ink. Other industrial sectors, such as textiles, packaging, glass, functional electronics, among others, are also using the technology more and more.

The process of manufacturing digital inks is not just about ultra-fine grinding of suspended particles to sub-micro or nano ranges. It is a set of more complex processes, such as solid / wet phase mixing, wetting out, interaction of chemicals with solid surface, stabilization, homogenization, and obviously the fine grinding into the required particle size distribution.

Our accumulated experience and leadership in this application has allowed us to develop and choose the best solutions from our wide portfolio, which covers the different stages of ink manufacturing process, always bearing in mind the specific requirements of each type of ink.

Thousands of tons of digital ink produced with NETZSCH equipment guarantee the confidence of hundreds of customers from all over the world.

Nano Applications

“Nano” is the buzzword of the day. Nano technology is a collective term for a broad pallet of applications that have to do with structures and processes on the nanometer scale: solid particles in suspensions and powders, dusts, drops of liquid in emulsions, fogs, sprays or foams whose primary dimensions are less than 100 nm. Nanoparticles have a very large specific surface, the surface atoms of which are usually very reactive. That is what makes nanoparticles so unique and results in their special properties.

With the aid of such particles, it is possible to manufacture extremely hard and scratch-resistant coatings, materials with new properties such as low-sintering ceramics, amorphous (transparent) metals, and materials with high tensile strength and fracture toughness at low temperatures or superplasticity at higher temperatures. Nanoparticles are smaller than viruses and bacteria. Therefore, as a rule, they can easily penetrate cells. This characteristic makes nanoparticles interesting for the pharmaceutical industry, since they can be used to transport “effective ingredients” through biological barriers such as the blood-cerebral barrier for example.

There are two ways to produce nanoparticles. With the condensation or “bottom-up” method, the particles are created through molecular aggregation of an existing substance in dissolved, liquid, or gaseous form. These sol-gel techniques, precipitation techniques, micro-emulsion and gas phase processes are advantageous in that it is possible to produce high-purity, practically mono-dispersed spherical particle systems. The disadvantage is that the maximum productive capacity is usually quite low. This means that, as a rule, these methods offer only limited capacity for scale-up.

The production of very fine particles through comminution of coarse particles is referred to as the dispersion or “top-down” method. High energy densities such as those achieved in agitator bead mills are required for such grinding tasks. Wet grinding is the primary mode of operation for agitator bead mills. They are employed in many branches of industry for comminution of raw materials as well as dispersing fine pigments and products of the “bottom-up” method.


Paint is a coating material based on organic binders and, depending on the composition of the binding agent, can contain organic solvents and/or water. The organic or inorganic pigments that are finely dispersed in the binder give the paint its color. In general, paint is composed of binders, solvents, fillers, pigments and additives. For the most part, the binder is colorless and cross-links the respective substrate with the pigment, which gives the painted surface the desired color quality. After the paint has been applied, the solvent evaporates and the color solidifies and dries.

The additives serve, for example, as preservatives, in film formation, in reaching a certain elasticity or suppleness or even in setting a particular viscosity. Surfaces of metal, wood, minerals or synthetic material can serve as coating substrates. Paint is not just for decorative purposes. It is used as a protective coating against the effects of weather, chemical and mechanical loads, for example in the automotive, construction, mechanical engineering and shipbuilding industries.

Pigments and Dyes

A world without color would be dull and drab. The elements and substances that make everything colorful are, on the one hand, divided according to the chemical structure into inorganic and organic colorants. On the other hand, the designation pigment or dye is geared toward how the colorant behaves in a particular medium. Therefore, the distinction between pigment and dye is not rigid and a single substance can be both a pigment and a dye at the same time.

Pigments are made up of particulate matter that is insoluble in its vehicle and therefore must be finely dispersed in a binding agent. Due to their optical properties they are used as chromophoric substances, for example in paints, printing inks or Inkjet inks or, thanks to special technical and chemical properties, as anticorrosive agents for example.

Dyes are also inorganic or organic colorants which, in contrast to pigments, are completely soluble in their vehicle (water or organic solvents). They are used, for example, to color textiles (textile dyes), plastics and plastic fibers and as chromophoric substances in food technology, e.g. beta-carotene in soft drinks.

Printing Inks

Printing inks are finely dispersed, liquid to pasty mixtures which are made up of colorants such as pigments, binders (oil-varnish) and additives such as thinners, wax dispersions, etc.

Printing inks are used in printing machines to print a wide variety of materials such as paperboard, paper, foil, plastic, metal, leather, etc.
The shape of these materials may be flat, cylindrical…. The composition of the printing inks depends on the printing method and the substrate to be printed.
