PLENARY KEYNOTE SESSION
The Technology and Application of Cylindrical Soft Polymer Lithium-Ion BatteryHe Wei, Ph.D., Assistant General Manager, EVE Worldwide Industries, Inc., China
Cylindrical Li ion batteries, such as 14500, 18650 and 26650 etc, have been in mass production & wide applications for many years. However, it was difficult to find products with size of less than 14500 in the application. In order to meet steady increase of both quality & quantity demand, EVE has made a lot of efforts to improve performance of products & production capabilities. Now, EVE has independently developed the first world-wide fully automatic production line of cylindrical Li ion batteries with soft package. Therefore, it is believed that demand of cylindrical Li ion batteries with soft package will be much increased in the near future.
Peter Cheng, Ph.D., Chief Scientist, HighPower International, China
Different kinds of cathodes and anodes with special stable and safety material coating can improve battery safety performance in some content, especially for high temperature short-circuit tests. Polyoxometalates (POMs) cathode material capacity is 2-3 times with better safety performance compared with traditional cathode material, which had been made by chemical synthesis method and completely different from traditional cathode material Roasting method. The cell energy density with this kind of cathode material is higher, and can be used in consumer market in coming days firstly.
Electrochemical Performance of High Purity Graphite From the Lac Knife Flake Graphite Deposit in Quebec, Canada
Joseph E. Doninger, Ph.D., MSc, Director, Manufacturing and Technology, Focus Graphite Inc.
Drill testing by Focus Graphite conducted on the Lac Knife graphite deposit identified the presence of 7.9 million MT of proven and probable reserves grading at 15% C. Pilot plant flotation tests confirmed that the large >80 mesh flake could be upgraded to 98.3% C and further purified to a level of 99.98% C. CR2016 Li-Ion coin cell battery tests conducted on the standard and fine grades of carbon coated, spherical graphite resulted in achieving reversible capacities of 364 and 365 mAh/g and first cycle irreversible capacity losses of 1.44% and 1.01%.
Dee Strand, Ph.D., CSO, Wildcat Discovery Technologies
Today’s carbonate electrolytes provide inadequate SEI formation in lithium ion batteries containing silicon anodes. Silicon’s large volumetric changes during cycling require more robust SEIs to achieve high reversible capacity and long cycle life. This presentation will focus on the development of novel electrolyte formulations that result in longer cycle life of full cells containing silicon alloy anodes. Key highlights include carbonate-free electrolytes that outperform standard EC/EMC formulations.

How Can We Make EV Battery Recycling Happen?Linda Gaines, Ph.D., Systems Analyst, Argonne National Lab
This presentation will contain more questions than answers. It is expected that in developing answers, it will become clear what technologies will make the most sense for recycling lithium-ion automotive propulsion batteries. Recycling technology must produce a viable product at a reasonable cost, in a way that complies with all health and safety regulations that might get implemented.
Novis Smith, Ph.D., Vice President, Technology, Retriev Technologies
Retriev recycles over 1 million pounds of li-ion battery per year. We are in development of a technology to capture the recycled cathode material in its functional state maintaining >95% of the energy and entropy that went in to the production. We will manufacture green li-ion batteries from the material and presently have sufficient supply for more than 10 million 18650 format cells or the equivalent cathode materials for prismatic and other format cells. Supply of recycled materials will soon double.

All solid-state thin-film batteries, which are produced by thin-film deposition technology, have special advantages, that is, intrinsically safe, thin and flexible, thanks to their unique thin-film shape.
George Kerchner, Executive Director, Rechargeable Battery Association (PRBA)
There are a number of key regulatory issues that could have a significant impact on primary and secondary battery manufacturers in 2015 and 2016. These include, but are not limited to, battery product stewardship state legislation in the U.S., new restrictions on shipping lithium ion and lithium metal batteries by air, new battery labeling requirements for large format lithium ion batteries and changes to the lithium battery testing requirements in the UN Manual of Tests and criteria.
Advanced Crash Testing and Simulations for Automotive BatteriesJohn Turner, Ph.D., Group Leader, Computational Engineering & Energy Sciences Group (CEES), Oak Ridge National Laboratory (ORNL)
We report results of an integrated computational and experimental program to simulate a battery’s electrochemical, thermal, and structural response under mechanical abuse. ORNL has developed the Virtual Integrated Battery Environment (VIBE), a high-resolution transient coupled-physics simulation environment for batteries, with emphasis on Li-ion but extensible to other chemistries. The model is being used to analyze and correlate with existing mechanical test data from ORNL and others, with new experimental tests on cells and cell-stacks developed and conducted by ORNL to support model development and validation.
Natural Gas as a Bridge to Hydrogen Fuel Cell Light-Duty VehiclesAndrew Burke, Ph.D., Institute of Transportation Studies, University of California, Davis
In this paper, detailed comparisons are made between various types of light-duty vehicles fueled with natural gas and hydrogen. The natural gas vehicles are designed as charge sustaining hybrid vehicles and the hydrogen fueled vehicles are powered by a fuel cell. All the vehicles have a range of 400 miles between refueling stops. The paper discusses the on-board storage of natural gas (3600 psi) and hydrogen (10000 psi) in terms of the volume and weight of the tanks required and how fuel storage affects the vehicle design.
BATTERY MANAGEMENT SYSTEMS
Battery and Advanced Vehicle Testing at Idaho National LabKev Adjemian, Ph.D., Department Manager, Energy Storage and Transportation Systems, Idaho National Laboratory
The Energy Storage & Transportation Systems department at Idaho National Laboratory (INL) has two major thrusts of activities which will be highlighted in this talk. The first, as the Department of Energy (DOE), Office of Energy Efficiency and Renewable Energy’s (EERE) primary center for battery technology testing is to independently test and verify battery performance and durability at the cell, module and pack level. The second is the Advanced Vehicle Testing Activity (AVTA) whose primary goal is to provide benchmark data for technology modeling, and research and development programs, by benchmarking and validating the performance of light-, medium-, and heavy-duty vehicles that feature one or more advanced technologies primarily featuring batteries and electric drives.
A Precision Stress Sensor for Monitoring Li-Ion SwellingJames Kaschmitter, Chief Executive Officer, MicroMetrics
Excessive swelling in Li-Ion pouch cells can be caused by high levels of lithiation in new high capacity anode materials, or by internal failure mechanisms in the cell that cause gas generation. MicroMetrics, Inc. has developed an ultra-thin silicon-based Contact Stress Sensor (CSS) for use in monitoring swelling in Li-Ion pouch cells. The ultra-thin form factor allows the CSS to be placed between cells, or cells and pack casing, to monitor pressure changes with cycling. The high accuracy of the CSS allows it to detect even minor increases in pressure due to cell gassing.

PANEL DISCUSSION: Challenges of Commercializing Energy StorageModerator: J. Norm Allen, Operating Partner, Potomac Energy Fund
Panelists: Richard Baxter, Chairman, Energy Storage Association; President, Mustang Prairie Energy
Jim Falsetti, Director, BQ Energy
Reyad Fazzani, Chairman and CEO, Regenerate, LLC
Energy storage before and after the customer meter has been nascent in the US until recently. Now the rapid reduction in solar system pricing, coupled with significant reduction in battery system pricing makes energy storage practical and attractive, especially on the customer side of the meter for residential and commercial building applications. This panel will discuss, from a venture capital perspective, whether grid energy storage is at a tipping point toward rapid growth spurred on especially by the rapid growth of solar energy. Or, are there still substantial obstacles to rapid growth of grid energy storage?
