Questions Regarding Funding Opportunity Announcements

Please contact the email address for questions regarding Funding Opportunity Announcements. Upon the issuance of a FOA, only the Contracting Officer may communicate with Applicants. ARPA-E personnel and our support contractors are prohibited from communicating (in writing or otherwise) with Applicants regarding the FOA. This “quiet period” remains in effect until ARPA-E’s public announcement of its project selections.

ARPA-E will not pre-assess an Applicant’s proposal. Prospective Applicants must review the technical requirements of the FOA and independently determine whether their proposed concept warrants a submission.

The Integration and Optimization of Novel Ion Conducting Solids (IONICS) program seeks to enable transformational electrochemical cells by creating components built with solid ion conductors that have a wide range of desirable properties including low ionic area-specific resistance (ASR), high chemical and electrochemical stability, high selectivity, good mechanical properties, etc. through innovative approaches to overcome tradeoffs among coupled properties. It also seeks to develop and apply methods for processing of solid ion conductors and their integration into electrochemical devices. Components built with solid ion conductors, especially separators, have the potential to serve as enabling platforms, as demonstrated by the wide application of Yttria-Stabilized Zirconia (YSZ) ceramics and perfluorosulfonic acid (PFSA) polymers (e.g., Nafion®). The IONICS Program Categories focus on specific electrochemical cells with high impact for the energy sector whose commercial potential will be significantly enhanced with improved components built from solid ion conductors.

The Program Categories include:

1. Lithium (Li) ion conductors that enable the cycling of Li metal without shorting

2. Selective and low-cost separators for batteries with liquid reactants (e.g., flow batteries)

3. Alkaline conductors with high chemical stability and conductivity

4. Other approaches that could achieve the IONICS Program Objectives
