The Technology and Application of Cylindrical Soft Polymer Lithium-Ion Battery
He 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.

Advanced Crash Testing and Simulations for Automotive Batteries
John 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 Vehicles
Andrew 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.

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 Swelling
James 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 Storage
Moderator: 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?
