It is widely recognized that fluorinated electrolyte additives and solvents are critical for enabling high energy Li-ion cells. In this presentation, we highlight how judicious combination of fluorinated electrolyte components improve overall cell performance. We describe the underlying mechanism by which fluorinated materials improve cell performance, using a combination of cell-level performance data and post-mortem analysis. We also summarize the challenges and opportunities for scaling the production of fluorinated materials.

Cabot’s R&D team has optimized the use and function of conductive materials in LIBs. In cathodes, high aspect ratio carbon nanotubes (CNTs) show clear benefits in imparting electronic conductivity at the lowest loadings. While carbon blacks enable efficient ionic conductivity and provide space necessary for Li+ transport. In silicon containing anodes, carbon nanostructures, a new class of novel crosslinked CNT materials, greatly improve the cycle life of the cell.

An overview on the most recent cathode active material (CAM) developments of BASF will be given that address the needs for higher energy density, lower cobalt contents, and for sustainable production. BASF is the only global CAM producer with research and production presence in all major regions.

Introduced on the market some 10 years ago as the ultimate option for very high energy density systems, Mn rich cathode materials never managed to make it to mass production. This lack of market enthusiasm was mainly due to intrinsic performance issues and simultaneous better value proposition from competing chemistries, mainly Hi Nickel based systems. The ongoing race towards more affordable vehicles, translated into lower US/kWh shed a new light on these materials which appear to be very suitable candidate for cost optimized designs. Topics covered: Presenting Umicore, global leader in active battery materials, Cathode material roadmap for xEV: Which chemistries for which applications? , Focus on Mn rich compounds: How can they answer today’s needs? Progress made in the technical development of Mn rich @ Umicore

High-capacity negative electrodes for lithium-ion batteries based on alloying materials like silicon suffer from a rapid capacity loss due to irreversible reactions of lithium with electrolyte components. One promising way to extend lifetime is by adding lithium prior to cell assembly-- pre-lithiation. The presentation will show latest results regarding steps towards the industrialization and incorporation of pre-lithiation in cell manufacturing overcoming cost and safety concerns.

Meeting skyrocketing global energy demand requires innovative battery materials that are manufactured at a velocity of scale.

Founded in 2016, LJT raised €30m in venture capital, employs >50 fte, and is working to ramp up its production technology to the GWh scale.

There is a demand from the global community that cell manufacturers adopt responsible and sustainable practices. However, in the increasingly competitive lithium-ion battery space, sustainability and cost control typically do not go hand-in-hand. For anode electrode process improvements, Livent has developed a dry electrode technology that is both sustainable and cost advantageous over the current state-of-the-art technologies. Using Livent’s dry electrode technology, anode electrodes with high first cycle efficiency can be produced in a single step. This task is accomplished by the incorporation of Livent’s LIOVIX, Printable Lithium Technology, into the anode-making process.

Solid-state batteries are among the most promising options for the future of EVs. Unlocking that future is more than a technology; it involves solving the supply chain, attracting & retaining talent and avoiding single-source/exclusive contracts. Addressing these as an industry will be important to the long-term success of solid-state. This presentation shows how.
