V.A Introduction
positive interfaces, development of new overcharge shuttles to further stabilize Li-ion cells, new ionic liquids to enable
higher voltage windows, and first principles modeling to understand and eventually to construct a more stable SEI.
The Modeling, Diagnostics, and Cell Analysis tasks involve the use of advanced diagnostics techniques, such as
FTIR, X-ray absorption fine structure (XAFS), X-ray diffraction (XRD), nuclear magnetic resonance (NMR) and other
techniques to investigate interfacial and other properties in Li-ion batteries. Several modeling approaches are used to
understand cell and fundamental material properties, including ab-initio calculations, macroscopic cell calculations, and
finite element simulations. Finally, standard cell making and testing techniques are developed and applied to provide a
common evaluation process for new materials.
The BATT program regularly solicits new proposals in each of the above four areas. The 2012 RFP will bein the
Modeling, Diagnostics, and Cell Analysis task area. In addition, BATT program management always accepts unsolicited
proposals on any advanced energy storage technology that significantly advances the state of the art is is appropriate for
the R&D focus of the BATT program. Unsolicited proposals are reviewed in concert with the solicited proposals.
