FAQ: Answers to frequently asked questions about Grillo zinc powder

What distinguishes our zinc powders?

Our zinc powders are only produced from selected, high-purity zinc qualities. We produce exclusively at our site in Goslar, Lower Saxony. In addition, our zinc powders are subject to strict and close-meshed quality control and inspection during and after the manufacturing process, so that only the highest qualities leave our premises.

How are our zinc powders made?

Our zinc powders are produced by Air-Atomization or by Spinning-Disk.

Are our zinc powders also suitable for soldering processes?

Our zinc powders are used as zinc-aluminium alloy powders for soldering aluminium components.

What is the shelf life of our powders?

We guarantee the properties of our zinc powders for a period of 6 months from the date of delivery if stored appropriately.

How should our zinc powders be stored?

Our zinc powders should be stored in closed original containers. Furthermore, the storage place should be clean and dry and the storage should take place at ambient temperature. Strong temperature fluctuations should be avoided.

What future markets do we see for our zinc powders?

In particular, the increasing use of renewable energies that are not continuously available requires environmentally friendly and sustainable storage of electrical energy. We see zinc-based energy storage as one of the approaches to a solution. For us, protection against corrosion with zinc powder also means a step towards a sustainable future. Here, the useful life of steel-based components is significantly increased.

    Zinc Powder Research

Intensive research for your ideally matched zinc powder

Interview: Dr Armin Melzer (General Manager Metal Division), Petra Gehrke (Head of R&D Zinc Powder) and Oliver Suchard (Head of Laboratory / QA / Application Technology Zinc Powder)

Our high level of research enables our customers to find the optimal solution for their products. Dr Armin Melzer

How are customised zinc powders developed at Grillo?

Gehrke: Development takes place in the form of projects, whereby each project is defined in terms of the type, duration and scope of the development work. In close cooperation with our customers, the technical requirements are discussed and defined. Subsequently, the corresponding zinc powders are produced via production trials.

What should be considered when developing zinc powders for different applications?

Suchard: Knowledge of the different areas of application is a basic prerequisite for customer-oriented advice as well as the development of the desired properties of the zinc powder. When developing zinc powder for batteries, detailed knowledge of the different battery types and battery systems is also crucial.

What are the developmental steps?

Gehrke & Suchard: The general project process is divided into planning, product or process development and analysis of the zinc powders and their evaluation. Together with our customers, specifications are developed and the properties expected of the zinc powder are defined. We then carry out production trials, analyse the zinc powder chemically and physically in our laboratory and, if necessary, also test it in our own Grillo battery construction. The results obtained are evaluated internally and with the customer. Samples are then taken in consultation with the customer. After the sampling phase, the results obtained by the customer are discussed and further adjustments are made if necessary.

Why is R&D so important for the zinc powder business?

Gehrke: Without expertise in zinc-based battery systems and other applications for zinc powder, no new, innovative zinc powder can be developed and successfully launched on the market.

What are the benefits for the customer of this high level of research?

Dr Melzer: Thanks to the high level of research, Grillo enables its customers to find the optimum solution for its products and, in addition, to reduce their own development effort.

Grillo has a state-of-the-art production site in Goslar. What makes it stand out?

Dr Melzer: Our technical competence for the development and production of our zinc powder is bundled at our site in Goslar. There we have a modernly equipped chemistry laboratory, a battery test system, a gassing laboratory and the laboratory equipment necessary for the characterisation of zinc powder. Our zinc powders are produced exclusively in Goslar. Due to its central location and excellent infrastructure, the Goslar site enables us to ship our zinc powder worldwide.

To what extent do you use your own research department for funded research projects?

Gehrke: For us, the development of zinc accumulators is an important, strategic future market for the zinc battery industry and thus also for ourselves. New applications such as 3D printing, precious metal recycling, coatings are also important for our future. Therefore, we work very closely with national and international universities and research institutions. This also includes funded research projects together with industry and university partners.

How zinc and water can charge smartphones

Nowadays, smartphones are constant companions. When the battery is flat on the road, many people are at a loss. The solution is a mobile charging option for on the go. This is exactly the topic we have dedicated ourselves to. In this project, we and our scientific partners aimed to develop a demand-oriented, location-independent generation of hydrogen (H2) for a fuel cell. Zinc was the game changer: hydrogen is produced through the chemical reaction of zinc and water. The low procurement costs of zinc are only one advantage.

With the help of zinc electric vehicules will drive more routes in the future

It is not yet possible to drive long distances in an electric vehicle without taking a charging break in between. The energy density of current lithium-ion batteries is not sufficient for this. Zinc-air batteries, on the other hand, have five times the energy density and could be the solution. Our goal with our research was to develop a scalable zinc-air battery that can be charged both mechanically and electrically. The special properties of zinc are excellent for this. In the future, electric vehicles can then be mechanically charged with so-called zinc slurries.

How zinc contributes to an optimal energy storage technology

For stationary applications, zinc-air energy storage systems are very advantageous. Whether low costs for active materials, the high availability of zinc or the good environmental compatibility of the materials – zinc-air energy storages could grow into an optimal storage technology. We have investigated different aspects of zinc-air technology in a joint project with other research teams. Our goal was to develop a cell design that is competitive and scalable up to the megawatt range.

Why batteries will soon be coming out of the printer

In order to be able to store regenerative energies in households or even entire apartment blocks, for example, lead-acid batteries have mainly been used up to now. The disadvantage: the batteries are not only expensive, but also un­flexible in handling and at the same time not scalable. The solution would be an inexpensive and rechargeable zinc-air battery. In order to realise this innovative power storage system, we researched with other research teams in a project funded by the Federal Ministry of Education and Research (BMBF) on a low-cost printing technology. New materials for zinc and oxygen electrodes were investigated for this printing process.
