PHEV Battery Performance in a Vehicle to Grid (V2G) Utilization Scenario: A Technological and Economic Analysis
Jay Whitacre, PhD, Assistant Professor, Materials for Electrochemical Technologies Lab, Dept Materials Science and Engineering, Carnegie Mellon University*
This talk will describe work done to examine the degradation of common LiFePO4-based Li-ion batteries when used in urban driving conditions combined with afternoon grid-level load shifting (V2G). A technical evaluation of cell performance will be given and an economic model will be presented that shows the potential benefits of using V2G/smart grid technology with PHEV battery packs.

Changing the Way the World Views Portable Power
Per Onnerud, PhD, Chief Technical Officer, Boston-Power Inc.
In this presentation, we will share insights into user demand for untethered mobility and the advancements in lithium-ion battery technology poised to fulfill that requirement. New benchmarks in cycle life, performance, reliability, fast charge, environmental sustainability and safety will be highlighted. We will also discuss a new industry model where battery providers work directly with designers of end-products, ranging from portable electronics to vehicles, to deliver whole new generations of products optimized to meet customers’ increasing demands for anywhere, anytime mobility.
Beyond Li-Ion, A Strategy for Step-Change Improvement in Energy Density
Steven J. Visco, PhD, Chief Technical Officer and Vice President, PolyPlus Battery Company
The invention of protected lithium electrodes (PLEs) enables the development of a new generation of ultra-high energy density batteries. These electrochemical systems are semi-fuel cells where a PLE is coupled with an external redox species supplied to the positive electrode (i.e. oxygen or water). Isolation of the oxidant from the battery housing is expected to yield benefits in terms of safety in that the energy for the cell reaction is not contained in the battery itself; this may be particularly important for large traction batteries. The unique aspects of these PLE cells offer step-change improvements in batteries on land, in the sea, and in medical devices. The state-of-the-art will be covered in the presentation.

CAM-7: A Unique Cathode Material Providing Both High Energy Density and High Power for Li-Ion
Brian M. Barnett, PhD, Vice President of Technology, TIAX LLC
Culminating several years' work, TIAX has developed CAM-7, a unique, high energy, high power, safe cathode material for lithium-ion batteries. CAM-7 is able to offer significant advantages for both automotive applications and non-automotive applications. CAM-7 is a patented lithium nickelate-class material that has been optimized for safety. CAM-7 is unique among cathode material options in that it combines extraordinarily high power capability (more than 130 mAh/g at 100C discharge rate) with the highest available energy density, more than 210 mAh/g to normal charging voltage (4.2 V). This talk will summarize the CAM-7 development effort and present data regarding CAM-7 performance in portable as well as transportation applications.
High Energy Density Lithium Cells
Sébastien Patoux, PhD, DRT/LITEN/DTH/LCE, French Atomic Energy Commission - CEA, France
The presentation will first focus on high capacity (LiMO2•LiMn2O3) layered oxides as a promising solution for the positive electrode of Li-ion batteries. We will present the latest results obtained at CEA-LITEN on this family of materials, with very good reversible capacity at the level of 250mAh/g at room temperature. At the negative electrode, the interest in silicon-carbon composites has been abundantly discussed in the literature. Here, several synthesis routes investigated at CEA-LITEN, from CVD process to mecano-chemical route, an others, will be discussed together with optimization of the electrode making. Results on 2-3Ah prototype cells will finally be reported with a significant improvement in energy density.
Nano-Li4Ti5O12 Based Lithium Ion Battery for HEV and PHEV Application
Veselin Manev, PhD, Director R&D, Altairnano Inc.
The performance of high specific power & high rate capability cells with nano-Li4Ti5O12 negative electrodes developed in particular for HEV and PHEV application will be discussed. Data for capacity retention during continuous discharge at up to 80C rate corresponding to 45 sec cell’s full discharge duration will be displayed. The cycle life in excess of 25,000 cycles, at 8C charge/discharge rate & 100% DOD will be presented. Particular attention will be paid on the excellent calendar life performance of Altairnano’s Li4Ti5O12 based cells. A data from accelerated calendar life test suggesting capacity fade below 1% after 25 years calendar life at room temperature will be displayed. Finally the results from safety tests performed on these cells showing no safety events will be displayed.
