9:00 What We’ve Learned from Testing >250,000 Cells: New Cell Evaluation Methods and Data Mining Techniques Derived from High Throughput Screening
Steven Kaye, PhD, CSO, Wildcat Discovery Technologies, Inc.
Wildcat Discovery Technologies uses a proprietary high throughput synthesis and screening platform for battery materials. Wildcat’s system produces materials in bulk form, enabling evaluation of its properties in a standard cell configuration. This allows simultaneous optimization of all aspects of the cell, including the active materials, binders, separator, electrolyte and additives. Over the past 3 years, we have screened over 250,000 cells, developing new cathodes, anodes, and electrolytes for a variety of battery types (primary, secondary, aqueous, non-aqueous). In this talk, I will discuss what we’ve learned from this work. Specifically, new analysis methods to extract more information from each cell, which performance metrics are most predictive of long term cycle life and other failure modes, and sensitivity of performance metrics to changes in cell components. I will also discuss new high throughput cell evaluation methods in use at Wildcat, including high precision coulometery and in-situ gas evolution measurement.
9:30 One-Dimensional Tin Nanostructures for Lithium-Ion Batteries
M. Grant Norton, PhD, Professor, School of Mechanical and Materials Engineering, Washington State University
Tin is an attractive anode for next generation lithium-ion batteries. The large volume change during cycling can be accommodated when the material is in the form of a 1-D nanostructure. Tin nanostructures are grown by electrodeposition and using electron microscopy we have determined the growth mechanism. This information has been used to control their formation on a range of substrates. In this presentation, we will also describe the results of in-situ lithiation/delithiation studies using a specially designed TEM holder and results obtained by combining the tin nanostructures with a flexible polymer electrolyte as a step toward a fully flexible battery.
10:00 Solid State Li-Ion Batteries
Hélène Rouault, PhD, R&D Project Manager in Advanced Batteries, French Alternative Energies and Atomic Energy Commission (CEA), France; and
Julio Abusleme, PhD, R&D Project Manager, Solay S.A., Belgium
The next generation of portable electronic devices which could revolutionize the smart communication access and control in very large domain of applications are requested to be unbreakable and bendable. Consequently, the components of such products as the display, the electronic circuit board and also the embedded power source have to offer flexible and resistant structure. CEA and Solvay jointly have so engaged a large program of development on innovative bendable lithium-ion batteries, using monolithic gelled structure from specific PVdF based inks, making them conformable and flexible.

11:00 Thermal Plasma CVD: An Economic Technology for Silicon Anodes
Roel C.M. Bosch, Manager Innovations, Roth and Rau B.V., The Netherlands*
For over a decade Roth & Rau is manufacturing thermal plasma coating systems for ultrafast deposition of silicon based materials. We have currently several collaborations running on the development of silicon anodes with very good results on capacity and cycle life. Key aspect is that thermal plasma technology allows for high deposition rates of amorphous silicon (>1mu / min) and for very controlled growth in terms of density/porosity and the ability to follow complex 3D morphologies such as nanowires, CNT’s and carbon fabrics. *In collaboration with: P. Kudlacek, W. Boonen, B. v. Gerwen, and D.M. Borsa
11:30 New High Capacity Embedded Silicon-Graphene Composite Lithium ion Battery Anode Material
Junbing Yang, PhD, CTO, California Lithium Battery, Inc.
If significant improvements in electric vehicle (EV) lithium ion battery (LIB) specific energy (Wh/kg) or energy density (Wh/L) is to be achieved in a timely and cost effective manner, there must be a shift from graphite-based anodes to new, high specific capacity anode materials such as the new uniformly embedded and uniquely stable silicon-graphene composite anode material developed and produced by California Lithium Battery Inc.

2:00 Reversible Overcharge Protection for Safer and Lasting Rechargeable Lithium Batteries
Guoying Chen, PhD, Research Scientist, Environmental Energy Technologies Division, Lawrence Berkeley National Laboratory
With the growing demand of EV and grid storage, the existing $11B Li-ion battery market worldwide is expected to exceed $43B by 2020. Lithium cells are known to suffer from safety and lifetime issues upon abuse, particularly overcharge/overdischarge following which energetic venting, ignition, and even explosion can occur. Current protection methods of using electronic controls add significant weight and volume to the pack. The use of internal shutdown mechanisms reduces the usable capacity and adds to the burden of the remaining cells in parallel circuits. A novel approach was developed at LBNL where electroactive polymers capable of forming a voltage-regulated, reversible resistive shunt between the current collectors were introduced to prevent cells from overcharge damage. Recent progress, including the development of electroactive polymers that provide protection for high-energy cells intended for vehicular applications and novel electroactive-fiber membranes that drastically reduce the cost and improve the stability of overcharge protection, will be presented.
2:30 Safety Standardization for Wireless EV Charging Systems
Joseph Bablo, Primary Designated Engineer, Underwriters Laboratories
As wireless charging innovation has gained momentum, so too has the development of safety standards that begin to address fire and shock hazards, as well as functional safety and interoperability.

4:30 Increasing Scrutiny and Regulation of Small Lithium Batteries
Jim Powell, President, Transportation Development Group LLC
In 2014, stricter shipping regulations take effect for small lithium batteries that may now be considered “Dangerous Goods” requiring a hazard label and shipper’s certification. This is a lot of work and expense to ship a few AA lithium cells or other batteries. New rules for ground transport have raised the penalty for an undeclared lithium battery shipment to $20,000 and $40,000 per violation for ground and air transport respectively.

9:00 Analytical Investigation of the Failure Mechanisms of Lithium-Sulfur Cells
Holger Schneider, PhD, BASF Corporation*
Lithium-sulfur batteries are attractive candidates for post-Li-ion battery systems, offering both superior theoretical capacities and thus high energy densities. However, their practical application is hampered by several severe challenges. We were able to show that the cell performance is strongly influenced by both the amount of electrolyte and the sulfur active material. Moreover, we performed extensive analytical investigations on the decomposition products and gases formed upon cycling the cells. Our findings are discussed in detail in this presentation. *In collaboration with: K.Leitner, H.Sommer, J.Kulisch, T.Weissa, M.Safonta, BASF and Karlsruhe Institute of Technology
9:30 High Temperature Li-Ion Batteries Through Thermally Stable Separators
Brian Morin, COO, Dreamweaver International, Inc.
With recent fires in batteries for the Boeing Dreamliner and Tesla S, thermal stability in lithium ion batteries is of primary concern. In this talk, we present batteries made using a separator that is stable up to 300 C, and also stable through significant fire events, and show the additional safety that can be achieved in batteries using these separators.
10:00 Modular Electrolyte Additives: Decoupling Uniform Deposition and Stability
Steven Kaye, PhD, CSO, Wildcat Discovery Technologies, Inc.
The stability and cycle life of lithium-ion batteries are limited by unfavorable reaction between the electrodes and electrolyte. To reduce this problem, electrolyte additives are used to passivate the cathode and/or anode with a protective coating. To function effectively, such additives must both deposit uniformly on the electrode surface and form an electrochemically inert coating. These dual constraints severely limit the set of viable additives. Wildcat Discovery Technologies has developed a new, modular additive concept in which additives are bound to a molecular core that enables uniform deposition on the electrode surface. Attachment of conventional additives to the core molecules provides improved SEI stability, increasing coulombic efficiency, cycle life, and thermal stability. Furthermore, by decoupling the requirements for uniform coating and chemical stability, new classes of additives can be used. In this talk, I will discuss the development of these modular additives as well as their performance with both commercial and future cell chemistries.

11:00 Battery Aging: Using Modeling to Predict Battery Life
Tom O’Hara, Global Business Manager, Advisory Services for Energy Storage, Intertek
Battery modeling and simulation helps manufacturers analyze operating conditions and design parameters for batteries and other electrochemical systems and processes to understand how they affect battery life and performance. In this presentation we will discuss the benefits of modeling and simulation of lithium-ion batteries. He’ll also explain how test results provide data to predict battery life, analyze implications of operating conditions and design parameters, and understand battery limitations.
11:30 Prototype Pre-Heat System for Electric Vehicles
David Baglee, PhD, Dept of Computing, Engineering and Technology, University of Sunderland, United Kingdom
The performance of electric vehicles depends strongly on the performance of its battery pack, which can be influenced by extreme cold temperatures such as those found in Northern Europe. A battery pack performance is reduced as temperatures often reach - 30. Batteries may suffer from slow start, reduced range and slow rate of charge. A solution is to pre-heat the internal core, a module or pack cell. In order to pre-heat and regulate thermal instabilities it is necessary to simulate winter conditions. Sunderland University are developing a thermal management system to characterize the effect of low temperature on battery performance and pre-heat the batteries to ensure capacity, power, charge and safety are not compromised.
12:00 High Performance Direct Carbon Fuel Cell by Using Pyrolyzed Carbon from Biomass and Waste Sources
Wenbin Hao, Dept of Chemical and Biomolecular Engineering, The Hong Kong University of Science and Technology, Hong Kong
The promise of direct carbon fuel cell arises not only from diversity of available fuels and high operating efficiency, but also a solid infrastructure for scale-up, including transportation, storage, and processing of fuels. In our work, three kinds of carbon fuels from carbon black (CB), bamboo fiber (BC) and waste paper (WPC) are investigated as the anode fuels in the intermediate temperature direct carbon fuel cell (DCFC). The surface compositions of the prepared carbons are carried out by X-ray photoelectron spectroscopy. The experimental results indicate that the carbon from new carbonaceous waste paper shows more elemental rich in Al, Ca and Mg than the other two carbons. The prepared carbons are tested in anode support type DCFC by using samaria doped ceria (SDC) as the electrolyte at 650˚C. The cell performance with the carbon generated from waste paper yielded a peak power density of as high as 225mW/cm2, which is about 2 times higher than that with carbon black. *In collaboration with: Xiaojin He, Yongli Mi

2:30 The Economic Case for Choosing an Electric Vehicle
Mike Sanislo, PE, President, High Energy Consulting, Inc.
Everyone wants to be green. Except when it costs money. What is the economic case for purchasing an electric vehicle? It depends on the benefit set relative to the best competing alternatives. The speaker will show the economic value for current electric vehicle offerings relative to what else can be purchased in the market. Early adopters are not necessarily driven by economics---the large markets are dependent, in part, on a compelling value proposition---one that says that an electric vehicle costs less than competing alternatives. The speaker will show the math as it exists with current commercial options and where the industry needs to go for the market to become large.
