Lithium-Ionen-Festkörperbatterien

Lithium-ion solid-state batteries

Solid-state battery cells (solid-state batteries) are being touted as the “next big thing” in electric vehicle technology because they offer the potential of particularly high energy density and high safety. However, there remain challenges to their technical maturity, particularly in manufacturing, cost, and performance. This seminar introduces how this battery cell technology works. This is accompanied by an overview of the wide variety of solid-state battery subtypes with their individual characteristics.

Since this technology is a completely new development, there are also hurdles for its use in battery systems. In particular,cost, energy density and producibility play a role here. Based on concrete examples and a roadmap developed from research projects, input from cell manufacturers and internal assessments, possible initial use cases of this promising technology are recommended.

You will get answers to the following questions:

• How do these solid-state batteries work?
• Where does this technology stand?
• What are its application potentials?
• What are the remaining hurdles to their widespread use?
• How do solid-state accumulators, solid-state batteries, solid-state batteries differ?
• What materials are the electrolytes in solid-state batteries made of?

On the subject

Battery technology is currently experiencing a tremendous upswing due to its greatly reduced costs and large increases in performance, such as the increase in electromobility and the use of batteries for the energy transition. However, requirements are also continuing to increase: greater energy density is desired for longer ranges for electric vehicles, or particularly high safety with good performance for air cabs, for example, or longer battery life for smartwatches. Solid-state lithium-ion batteries have the potential to meet these increasing requirements. However, they do not yet have the same level of maturity as conventional lithium-ion battery technology.

Objective

The seminar is designed to help participants understand the functionality, application potential and challenges of solid-state batteries. Based on this, they will be able to make their own initial assessment of the usability of this technology for many application scenarios and its significance for their own company.

Participant group

The seminar is aimed at employees, decision-makers and managing directors as well as engineers and people in similar positions. Industries that use batteries or are active in the battery context are addressed. E.g. in electromobility and aviation: developers, manufacturing companies, recyclers, plant engineers, etc., who are looking for a deeper understanding of the topic of solid-state batteries. This is a topic where many great goals and successes are reported in the media, but whose potential and basis can hardly be assessed without background knowledge. Prior knowledge of chemistry is not required, but a technical background is helpful. Upon request and agreement among participants, presentations can also be held in German – slides will be English.
