Deutsch Roadmap 2030+ for sustainable batteries
Sustainable batteries
The European Research Initiative Battery 2030+ has published a long-term roadmap that includes measures to develop more sustainable batteries for future applications. The aim is to optimise the development process of future connected batteries using digital technologies such as artificial intelligence and the like.
The battery roadmap relies on faster development of interfaces and materials, also on a "Batteries Interface Genome (BIG)", which is to serve as a basis for understanding the chemical processes within the battery. Further in the field of view are extreme temperatures, mechanical stress, excessive load in operation and aging processes, which significantly influence the life span of the batteries. New ways are to be found to reduce battery failure in the future. For this purpose, new sensor concepts are to be developed that detect early stages of battery failure and undesirable side reactions.
The researchers and marketing specialists of European companies believe that Europe should pay more attention to these aspects in the increasingly important market segment.

Solid-ceramic solid-state batteries
Solid-state batteries
Various research institutes and companies are working on the development of solid-state batteries, including the PSI in Würenlingen. This involves drying electrodes. The liquid electrolyte in the previous Li-ion battery applications is fire-hazardous and therefore there are strict and cumbersome transport regulations. In the planned ceramic solid-state batteries, both the cathodes and the electrolyte are made of oxidic or sulphide materials. These batteries thus not only do without liquid components, but also without polymer components. Companies develop scalable manufacturing solutions for the drying and sintering of oxidic composite cathodes and solid electrolyseparators. However, it will take some time before this technology can be delivered in large quantities.

High energy density for new Li-ion capacitors
New Li-ion capacitors
Mobile systems and devices usually require powerful Li-ion batteries. These are specially manufactured for the respective industrial application and secured by sophisticated electronic protection technology. There are a few things to keep in mind here: In order to avoid fire danger and the like, the worldwide regulation UN 38.3 requires a transport test form from 2020, which must be attached to the shipment. In 8 individual tests, the behavior of the cell or battery at extreme temperatures and much more is described in detail in advance.
The new Li-ion capacitors are environmentally friendly, do not require heavy metals, are RoHS compliant and are not subject to the European Battery Regulation and therefore do not require the UN transport tests described above. Externally, they resemble the aluminium electrolyte capacitors, but have a completely different design internally. The current capacity is 40, 100 and 200 Farad. What about these novel Li-ion capacitors in connection with the Li-ion batteries that are common today? A replacement is not yet possible due to the capacity and energy technology achieved so far, but should remain in focus in the future.

Interview Corona times
Corona times are not easy times.
We talked to Guido Küng, Managing Director and founder of Accutron AG, about this.
JF: What's going on at Accutron at the moment? Batteries are needed everywhere in mobile systems.
Guido Küng (GK): Since about 80% of our batteries go to medical devices, we are now quite busy.
JF: You have a large battery range. What kind of batteries are mainly bought and what about delivery times in general?
GK: 90% lithium batteries are used, the remaining 10% is distributed between lead batteries, NiMh and NiCd. Delivery times are sluggish due to the large backlogs in Hong Kong.
JF: Since 2020, the test certificates have been mandatory in accordance with UN 38.3 for the transport of lithium batteries at the time of delivery. Is there still any ambiguity in this regard among your customers and is this generally complied with in accordance with the rules?
GK: Until the end of 2019, UN38.3 (passport for lithium batteries) was still mandatory informally, but since January 2020 it has been required by law. Each customer is therefore obliged to bear the only one-time costs for the UN38.3 test.
JF: What are the most common questions from your customers at the moment?
GK: Can my delivery come a little earlier?
JF: You are now wearing protective masks in your sales program. What types are these and what are the respective delivery times? How do you assess the demand, as the whole world is looking for appropriate masks.
GK: Our Chinese friends/suppliers are very concerned about us here because they themselves have been through exactly what we are doing here now. So they offer us protective masks from their stocks. We have published this on our website, but there is no reaction yet. We now know that the major distributors now have such masks in their assortment. (It was meant to be a favor anyway.)
JF: How do you assess the market situation in your specific market in the coming months?
GK: That is very difficult to assess at this stage. My personal wish is only that everything gets back on track, it really hurts to hear how many people and businesses are doing very badly now! I keep my fingers crossed!
