Lithium Battery Chemistry Symposium

Recent Advancements in Battery Chemistries

19 - 20 January 2021 ALL TIMES CET

In order to increase market share, new electric vehicle batteries must increase their performance through improved chemistries, while remaining cost competitive with conventional internal combustion engine automobiles. By creating safe and reliable long range batteries through improved chemistries, automotive electrification goals can be achieved. The Lithium Battery Chemistry Symposium will unite automotive OEM companies, their supply chain, and academic researchers to discuss technological advances and commercial viability. Presentations will focus on advances in high-energy lithium-ion chemistry as well as other chemistries, including lithium-metal systems, silicon anodes, NMC cathodes, and solid-state technologies.

Automotive Solutions For High-Energy Electrodes

Franz Nietfeld, Head of “Cells And Battery-Modules” at Mercedes-Benz AG

Mercedes-Benz is committed to climate protection and air pollution control. Therefore, we are planning electrification for all segments. To support this ongoing effort, Mercedes-Benz research and development departments continuously work on advancing battery technology. To achieve class-leading product, it is crucial that we have our own deep insight into cell and battery technology including knowledge of materials and simulation and collaborate with strong technology partners. Mercedes-Benz is convinced that further improvements in energy density and performance of lithium ion cells will further promote the electrification of drivetrains. While the last decade concentrated on improving  cathode materials and  electrode design, we believe that major improvements in anode and electrolyte technologies will even further push the performance in the coming years. Hurdles such as low cyclic stability and dimensional changes of the cells have barriers in the industrialization of novel anode technologies. Mercedes-Benz and our partners are confident these challenges will be overcome in near future. This presentation will give the audience a snapshot of our strategy.

Automotive Solutions for High-Energy Electrodes

Kurt Kelty, Vice President, Automotive, Sila Nanotechnologies, Inc.

Advancements in the capabilities of lithium-ion batteries have slowed down in the last decade. As conventional electrode materials approach their theoretical limits, substantial gains in battery energy density only come as a trade-off in safety or performance. My talk will introduce an innovative drop-in-replacement nanocomposite silicon-based anode powder that completely replaces graphite and offers around 5 times higher gravimetric capacity and enables 20% higher energy density (Wh/L) today over state-of-the-art lithium-ion to power portable electronics and electric vehicles. The unique features of this micron-scale anode material include high first cycle efficiency, very low volume changes during each cycle and very low lifetime electrode swell.  This enables battery manufacturers to attain long cycle stability with no prelithiation. The material is 100% compatible with existing lithium-ion factories and is manufacturable at global scale using commodity precursors

Enabling Strategies for High-Loading Si-Anodes

Egbert Figgemeier, PhD, Senior Manager, IEK 12, Helmholtz Institute Muenster

During the last decade, silicon has turned out to be the most promising element for boosting the capacity of anodes for lithium ion batteries. Nevertheless, in commercial cells blends of silicon with graphite are applied reflecting the inherent challenges when trying to stabilize the battery performance over time and usage. The presentation summarizes the most promising and most recent strategies to overcome these challenges by pre-lithiation and electrolyte additives.

Energy Density Limitations in Present Cathode Materials

Karin Kleiner, Assistant Researcher & Chair, Tech Electrochemistry, Technical University of Munich

Charging layered oxides such as NCMs means storage of energy in a metal-oxygen host structure – it proceeds via a reversible oxidation of Ni and hybridization with O. Once Ni-O hybrid states are formed, irreversible reactions set. The lack of ionic Ni limits the reversible capacity. Moreover, the degree of hybridization, which varies with the Ni content, triggers the electronic structure and thus the operation potential of the cathodes.

13:20

Cathode Materials for Solid State Batteries and Their Requirements

Juergen Janek, PhD, Professor, Solid State Ionics & Electrochemistry, Justus Liebig University Giessen

The quite different chemical environment and mechanical constraints in solid state batteries create the demand for specifically designed cathode materials. The key issues will be briefly analyzed and the trend toward single crystalline NCM/NCA is reviewed.

Kenan Sahin, President, CAMX Power

CAMX has been focused on high nickel cathode materials for over a decade, engineering the interior of the secondary particle, having received global patents for the inventions. We will present in more detail our paths to lower cobalt, improve temperature performance, reduce impedance growth, mitigate cracking, and expand SOC operation.

      Sandeep Unnikrishnan, Program Manager, High Performance Batteries, Holst Centre

      Interfacial engineering is seen as the key to enable more reliable and durable Li-ion batteries. A stable artificial SEI on the high-voltage cathode side and on the anode side are crucial for long-term cyclability of the battery. Compared to pre-passivation of active materials, post-passivation of electrode foils has the benefit of lower interfacial electronic impedance. In this presentation, an innovative high throughput scalable technology will be presented that can do atmospheric pressure, gas-phase passivation of electrode foils for next-generation battery applications.

      Peter Kritzer, rer. nat., E-Mobility & Batteries, Freudenberg FST GmbH

      Increased energy density on cell & system level as well as new trends of "Super Charging" result in greater safety challenges. The presentation will show two system components designed to contribute to the improvement of battery safety: a) DIAvent - Overpressure valves with reversible capabilities. and b) Heat Shields - thermal barriers counteracting thermal propagation as well as mechanically balancing the cell modules. Additional innovative concepts will be explored aimed to enhance the safety of future battery systems. To best achieve the targets of each individual battery system, it is highly recommended that specific joint development is needed.
