KEYNOTE PRESENTATION

1:50 Practical Solutions to Lower the Cost of Batteries

Kenneth GouldKenneth Gould, e-Mobility Technical Systems Engineer, Porsche Cars North America

What is being done in practical terms to lower the cost of batteries? This presentation examines the practical solutions that we have today and explore what future innovations are most likely to deliver a lower cost and higher-energy density battery.


ADVANCES IN HIGH-CAPACITY CATHODE MATERIALS

2:20 Safe High-Energy Li-Ion Technology Using Lithium Manganese Phosphate (LMP)

Saori TokuokaSaori Tokuoka, Ph.D., Research Scientist, R&D, Saft

Saft has developed thermally stable cathode materials for high-energy and safe Li-ion cells. Main cathode material is lithium manganese phosphate (LMP), which has clearly shown improved safety feature comparing to conventional lithium metal oxides, with increased energy density over lithium iron phosphate. Not only excellent for safety, LMP is also a viable candidate for long-cycle life, which requires 500-600 cycles with 80% of capacity retention.

2:50 High-Capacity Multivalent Cathodes for Advanced Lithium-Ion Batteries

Jagjit NandaJagjit Nanda, Ph.D., Senior Staff Scientist, Materials Science & Technology Division, Oak Ridge National Laboratory (ORNL)

I examine recent developments and challenges associated with high-voltage (5V) cathodes such as lithium manganese-rich oxides and high-voltage spinel phases, as well as a few plausible approaches to improve phase stability and cycle life. As an alternate approach, I also discuss recent developments in multivalent, transition metal (TM)-based cathodes that can in principle reversibly transfer two lithium ions per TM.

4:15 High-Potential NMC Cathode Materials - A Route to High-Energy Density Li-Ion Batteries?

Marca DoeffMarca M. Doeff, Ph.D., Staff Scientist, Lawrence Berkeley National Laboratory

Our recent work has been directed towards understanding what controls the high-potential behavior of NMC materials, using a combination of microscopy (scanning tunneling electron microscopy/electron energy loss spectroscopy, STEM/EELS) and x-ray synchrotron techniques such as soft x-ray absorption spectroscopy (sXAS). To further ensure stable cycling, electrolytic solutions with improved oxidative stability also need to be used, perhaps in conjunction with coatings such as those produced by atomic layer deposition processing.

4:45 Synthesis and AlF3 Surface Coating of High-Capacity Cathode to Improve Energy Density and Cycle Life

Youngho ShinYoungho Shin, Ph.D., Principal Process Development Engineer, Argonne National Laboratory

The precursors of two high-capacity cathode materials
(Li1.47Ni0.16Mn0.67Co0.16Oy, Li1.07Ni0.61Mn0.33Co0.06Oy) were synthesized by carbonate and hydroxide co-precipitation methods. The physical and electrochemical properties of pristine and AlF3-coated materials were evaluated and it is demonstrated that 0.5 wt% AlF3-coated material shows the highest first discharge capacity (304 mAh/g) and 4 wt% AlF3-coated material shows only 1% capacity drop after 30 cycles.

Marca M. Doeff, Ph.D., Staff Scientist, Lawrence Berkeley National Laboratory

8:50 New Long-Life Lithium-Ion Battery with Electrically Conductive Corrosion-Resistant Ultrananocrystalline Diamond-Coated Natural Graphite-Copper Anode

Orlando Auciello, Ph.D., Endowed Chair Professor, Materials Science and Engineering and Bioengineering, University of Texas at Dallas

Novel electrically conductive/corrosion-resistant nitrogen-deposed ultrananocrystalline diamond (N-UNCD) coating provides excellent chemically robust encapsulation of commercial natural graphite (NG)/copper (Cu) anodes for Li-ion batteries (LIB), providing a solution to the problem of LIBs’ anode materials degradation. LIBs with N-UNCD-coated NG/Cu anodes exhibit ≥ 10x longer charge/discharge life cycle than current commercial LIBs.


FEATURED PRESENTATION
9:20 Future Cathode Materials and Their Challenges for Automotive Li-Ion Cells

Odysseas PaschosOdysseas Paschos, Ph.D., Research Battery Technology, BMW

This presentation highlights BMW’s dedicated efforts to overcome challenges and issues related to future-generation Li-ion cell technologies. This talk outlines issues and challenges that future-generation materials possess and discusses efforts that can improve the performance of the materials from an energy density and lifetime point of view, in order to be utilized in automotive Li-ion cells.

 

9:50 What’s New with Metal-Oxygen Batteries? An Atomic-Scale Perspective

Donald SiegelDonald J. Siegel, Ph.D., Mechanical Engineering Department, University of Michigan

Metal-oxygen batteries continue to attract interest due to their high theoretical specific energies. However, several challenges must be overcome before these batteries can be viable. This presentation describes multiscale computational studies aimed at revealing the atomic-scale mechanisms responsible for these limitations. Based on these findings, opportunities for improving cell performance will be discussed.

FABRICATION AND DESIGN OF
ELECTRODE MATERIALS

11:00 Si-Based Alloy Negative Electrodes for Li-Ion Batteries

Mark Obrovac, Ph.D., Associate Professor, NSERC/3M Canada Ltd.; Industrial Research Chair in Battery Materials, Department of Chemistry, Dalhousie University

Si-based alloys can have significantly larger volumetric and gravimetric energy density than graphite when used as a negative electrode in Li-ion cells. However, Si expands in volume by 280% upon full lithiation. This can cause structural deterioration of the anode material and anode coating. In this presentation the performance of Si alloy materials will be discussed in relation to their composition and microstructure.

11:30 Conduction Phenomena in Atomic Layer Deposition Coatings on Nanoscale Electrode Materials

Corey LoveCorey T. Love, Ph.D., Materials Research Engineer, U.S. Naval Research Laboratory

Many battery electrode materials can only achieve high specific capacity at the nanoscale. We use nanoscale atomic layer deposition (ALD) of Al2O3 coatings onto nanostructured silicon as a model anode composite materials to show the chemical and mechanical advantages on thin coatings. Our combined theoretical and experimental efforts seek to understand conduction phenomena at the nanoscale and provide suitable ALD-coating strategies to mitigate deleterious surface reactions and mechanical fracture.

Using ceramic coated separated separator can greatly improve Li-ion safety, battery cycling, rate capability with greatly increased energy density (higher charge voltages). In addition, we will also discuss Li-ion safety to human beings by differentiating various battery internal shorts (>95% field incidents) that can create different levels of hazards.
