Battery Update

News from our battery research team

In the Battery Update, researchers from Fraunhofer ISI discuss current debates and issues related to battery research, production and development. Along the entire battery value chain, i.e. from raw materials, components, the battery cell, battery markets and recycling, relevant topics are adressed and critically discussed.

On this page we collect all articles of our Battery Update. You can also subscribe to the Battery Update via RSS feed.

You can find interesting articles on other scientific topics in the Fraunhofer ISI blog.

  • Solid-state batteries: Publications by origin and announced cell production capacities by planned location

    Solid-state batteries (SSBs) have gained in importance in recent years and almost all well-known OEMs mention the technology on their development roadmaps, sometimes with quite specific dates for their implementation. But have SSBs already reached the necessary technological maturity for introduction in the automotive market? Alongside the manufacturers' commercialization announcements, there are still reports from research and development that suggest that there are still major challenges on the road to mass production.

  • Comparison of alternative battery technologies: technology maturity, market potential and sustainability benefits
    © Fraunhofer ISI

    The growing global demand for batteries is currently covered for the largest part by lithium-ion batteries. However, alternative battery technologies are increasingly coming into focus due to geopolitical dependencies and resource availability. What alternatives to lithium-ion batteries can meet the growing demand, ease the raw material situation and reduce geopolitical dependencies? How can supply chains be established in such a way that a resilient and technologically sovereign battery ecosystem can be created in Europe? And what about sodium-ion batteries, already used in electric vehicles in Asia?

  • Solid-state battery roadmap with different cell concepts and their expected start of industrial pilot production
    © Adapted from Thomas Schmaltz, Felix Hartmann, Tim Wicke, Lukas Weymann, Christoph Neef and Jürgen Janek (2023): A Roadmap for Solid-State Batteries; in: Advanced Energy Materials (Volume 13, Issue 43/2023) published by Wiley-VCH GmbH

    Solid-state batteries are regarded as a promising further development of lithium-ion batteries. Different materials are available for the various components. Which ones could be successfully commercialized in (hybrid) cell concepts in the future?

    Prices for key battery raw materials have been subject to enormous fluctuations over the past two years, putting an end, at least temporarily, to the trend of falling battery cell costs. In its Battery Update, Fraunhofer ISI points out which role the design of supply contracts plays in pricing and how the changes in raw material prices affect the costs of different lithium-ion battery technologies.

  • Global battery production with LFP and NMC/NCA cathode material between 2022 and 2030

    The cathode is a central component of a lithium-ion battery cell and significantly influences its cost, energy density, i.e. relative storage capacity, and safety. Two materials currently dominate the choice of cathode active materials for lithium-ion batteries: lithium iron phosphate (LFP), which is relatively inexpensive, and nickel-manganese-cobalt (NMC) or nickel-cobalt-alumina (NCA), which are convincing on the market due to their higher energy density, i.e. their ability to store electrical energy. Our analysis shows where in the world how much of which cathode material will be used in battery production and by when.

  • Open-source database for lithium-ion batteries released

    by Steffen Link / March 07, 2023

    The "BetterBat" research project has released an open-source database of over 300 lithium-ion battery cells from various manufacturers, with continuous updates. It allows industry and research institutions to benchmark battery cells and determine their suitability for various applications.

  • Anteile der weltweiten Produktion von Anoden, Kathoden, Elektrolyt und Separatoren

    It is well known that a large part of battery cell production takes place in Asia, more precisely in China, Korea and Japan. However, it is often overlooked that this market dominance is even more pronounced in the prefabricated production steps of battery manufacturing. More than 90 percent of the main starting materials of a battery cell (i.e. anode, cathode, separator and electrolyte) come from these three countries.
