2016 PEER REVIEW
The 2016 Department of Energy (DOE) Energy Storage Program Peer Review and Update Meeting was held Sept. 25-28 at the Renaissance Washington DC Dupont Circle Hotel, Wash-ington, DC. The three-day event was sponsored by the Dept. of Energy’s Energy Storage Sys-tems (ESS) Program at Sandia National Laboratories.
The theme of the 2016 Peer Review was “iStorage” to reflect the innovative, integrated, intelligent, and international nature of current and developing research and electricity delivery. In research and academia, resources such as the DOE OE’s ESS website and the DOE Global Energy Storage Database provide a basis for continuing and expanding technologies. In delivery and distribution, the theme points to Energy Storage Applications (Apps), Devices (including patents and potentially commercial items), Technologies (varied), and Systems (demonstration and analytics), including:
• Two-way digital communication technology to devices associated with the grid.• Self-healing distribution networks from power disturbance.• Enhanced cyber-security, handling sources of electricity like wind and solar power,
andintegration of electric vehicles onto the grid.

The United States Department of Energy (U.S. DOE) is pleased to welcome you to the annual Office of Electricity Delivery and Energy Reliability (OE) Energy Storage Program Peer Review.
HOW HAS DOE’S ENERGY STORAGE PROGRAM EVOLVED?First we developed technologies, then we developed a community of interested people and we are now trying to translate that into industry. Hardly anyone knew what energy storage was. Now, there are energy storage conferences worldwide almost every week of the year. The concept has gotten the attention of not just the US, but also Germany, China, Japan, Korea; everyone is talking about energy storage. WHAT IS THE FUTURE OF ENERGY STORAGE?As technology gets more effective, the cost will decrease, and the safety of the systems will
increase and as we have more applications and more examples, we will refine the regulatory structure and the acceptability of the storage will reach a degree where it will be considered standard. DOE’S annual Peer Review serves as an opportunity for experts to provide analysis and guidance to the researchers who are carrying out DOE-funded projects. The panelists review the projects and use the following criteria:• Completion of basic and applied research• Appropriateness of approaches and methods• Competency of research personnel, and• Adequacy of resources

SANDIA NATIONAL LABORATORIES (SNL)Sandia’s energy storage program addresses a range of topics in materials and systems as well as power electronics related to energy storage. Sandia researchers have addressed the high cost of membranes—a critical bottleneck in flow battery commercialization—by developing a new class of polymeric membranes with superior electrochemical properties and lower cost starting materials. Along with conducting extensive research in battery technologies, including lower temperature Na batteries and rechargeable alkaline batteries, Sandia has also developed lightweight nanocomposite materials for flywheels with increased rotational speeds.
PACIFIC NORTHWEST NATIONAL LABORATORIES (PNNL) The Applied Materials and Performance group includes materials scientists and chemists developing innovative synthetic approaches for fabrication of new materials and relating extrinsic material properties to their chemical/physical properties at the atomic, molecular, and nanoscale. Interfacial phenomena are a particular interest, including functionalization of the surfaces of nanomaterials, catalyst/catalyst support development along with charge and mass transport across interfaces. The division’s capabilities in soft materials generally reside in this group. Another portion of the group contains physicists and materials scientists specializing in vacuum-deposited thin-films with the unique ability to accommodate rigid substrates up to 2 meters in diameter in addition to rolls of flexible (plastic) substrate (roll-to-roll processing).
Internationally recognized expertise in organic electronic materials and devices (used in flat-panel displays, solid-state lighting, organic semiconductors and organic photovoltaics) also resides in this group. The group maintains significant laboratory holdings (more than 10,000 sq ft) for the synthesis and characterization of these materials and systems, mostly in the form of wet chemistry labs or labs with large, specialized vacuum deposition systems.
OAK RIDGE NATIONAL LABORATORIES (ORNL)From its beginnings in World War II’s Manhattan Project, ORNL has had a distinctive materials science program. Their core strengths are in three main areas: materials synthesis, characterization, and theory. In other words, they discover and make new materials, study their structure, dynamics and functionality; and use computation to understand and predict how they will behave in various applications. Today, materials science research benefits from ORNL’s integration of basic and applied research programs and strong ties among computational science, chemical science, nuclear science and technology, neutron science, engineering, and national security. This broad approach to research is allowing ORNL to develop a variety of new materials for energy applications and transfer these new materials to industry. We have developed advances in ways to improve materials processing to increase the performance of new materials while reducing processing cost. These advances have resulted in a broad portfolio of ORNL materials and technologies in the nuclear, automotive, and structural materials industry.

REGULATORY ENVIRONMENT (SNL & PNNL)Sandia supports research to enhance the regulatory environment for energy storage through a range of activities. These include estimating the value of energy storage for different applications and scenarios; developing control strategies that maximize revenue or benefit to the grid; identifying new control strategies and applications for energy storage; assessing public policy to identify and mitigate barriers for energy storage; developing standards; and evaluating projects.
STRATEGIC OUTREACH (SNL & PNNL)Sandia collects key information on current and future storage technologies and acts as a clearinghouse for the information so that it can be effectively disseminated among key stakeholders and the community. Outreach activities include conducting strategic communication initiatives, managing the Energy Storage Systems website, improving the DOE Global Energy Storage Database, updating the DOE/EPRI Energy Storage Handbook, and organizing the Peer Review meeting and the Electrical Energy Storage Applications and Technologies Conference.
VALIDATED SAFETY & RELIABILITY (SNL & PNNL)Sandia has a significant focus on safety and reliability of grid energy storage systems. This effort includes coordinating DOE Energy Storage Systems (ESS) Safety Working Groups which bring together over 150
stakeholders from industries that range from national laboratories, electric utilities, standards organizations, and manufacturing companies. The working groups are exploring gaps in safety R&D; enabling the development of codes, standards, and regulations (CSR); and educating first responders on storage system safety. Sandia also provides workshops and organizes technical conferences, including the Energy Storage Safety Forum which is slated to become an annual technical meeting for the world wide research community.
POWER ELECTRONICSSandia is advancing power conversion systems (PCS) for grid-tied and off-grid applications. This is driven by the development of new semiconductor switching circuits, as they determine the overall cost, reliability, and performance of the converter. Next generation PCS use advanced semiconductor materials known as wide band gap semiconductors (i.e. Silicon Carbide and Gallium Nitride) that allow for faster switching frequencies, improved voltage breakdown characteristics, and higher operating temperatures. These high voltage switches, in conjunction with advances in ceramic capacitors, controls, magnetics, and packaging, lead significant improvements in system performance through increased power density and efficiency compared to PCS systems using silicon devices.

LOW-TEMPERATURE NANOSOLDERSPatent no. 9,463,532Timothy J Boyle, Ping Lu, Paul T Vianco, Michael E Chandross
ABSTRACTA nanosolder comprises a first metal nanoparticle core coated with a second metal shell, wherein the first metal has a higher surface energy and smaller atomic size than the second metal. For example, a bimetallic nanosolder can comprise a protective Ag shell “glued” around a reactive Cu nanoparticle. As an example, a 3-D epitaxial Cu-core and Ag-shell structure was generated from a mixture of copper and silver nanoparticles in toluene at temperatures as low as 150.degree. C.
HYDROTHERMAL SYNTHESIS OF BISMUTH GERMANIUM OXIDEPatent no. 9,518,219Timothy J Boyle
ABSTRACTA method for the hydrothermal synthesis of bismuth germanium oxide comprises dissolving a bismuth precursor (e.g., bismuth nitrate pentahydrate) and a germanium precursor (e.g., germanium dioxide) in water and heating the aqueous solution to an elevated reaction temperature for a length of time sufficient to produce the eulytite phase of bismuth germanium oxide (E-BGO) with high yield. The E-BGO produced can be used as a scintillator material. For example, the air stability and radioluminescence response suggest that the E-BGO can be employed for medical applications.
THICK ELECTRODES INCLUDING NANOPARTICLES HAVING ELECTROACTIVE MATERIALS AND METHODS OF MAKING SAMEPatent no. 9,577,250Jie Xiao, Dongping Lu, Jun Liu, Jiguang Zhang, Gordon L Graff
ABSTRACTElectrodes having nanostructure and/or utilizing nanopar ticles of active materials and having high mass loadings of the active materials can be made to be physically robust and free of cracks and pinholes. The electrodes include nano particles having electroactive material, which nanoparticles are aggregated with carbon into larger secondary particles. The secondary particles can be bound with a binder to form the electrode.
HIGH PERFORMANCE, DURABLE POLYMERS INCLUDING POLY(PHENYLENE)Patent no. 9,580,541Cy Fujimoto, Harry Pratt, Travis M Anderson
ABSTRACTThe present invention relates to functionalized polymers including a poly(phenylene) structure. In some embodiments, the polymers and copolymers of the invention include a highly localized concentration of acidic moieties, which facilitate proton transport and conduction through networks formed from these polymers. IN addition, the polymers can include functional moieties, such as electron-withdrawing moieties, to protect the polymeric backbone, thereby extending its durability can be beneficial for any high performance platforms that employs proton exchange polymeric membranes, such as in fuel cells or flow batteries. POLYOXOMETALATE ACTIVE CHARGE-TRANSFER MATERIAL FOR MEDIATED REDOX FLOW BATTERYPatent no. 9,548,509Travis M Anderson, Nicholas Hudak, Chad Staiger, Harry Pratt
ABSTRACTRedox flow batteries including a half-cell electrode chamber coupled to a current collecting electrode are disclosed herein. In a general embodiment, a separator is coupled to the half-cell electrode chamber. The half-cell electrode chamber comprises a first redox-active mediator and a second redox-active mediator. The first redox-active mediator and the second redox-active mediator are circulated though the half-cell electrode chamber into an external container. The container includes an active charge-transfer material. The active charge-transfer material has a redox potential between a redox potential of the first redox-active mediator and a redox potential of the second redox-active mediator. The active charge-transfer material is a polyoxometalate or derivative thereof. The redox flow battery may be particularly useful in energy storage solutions for renewable energy sources and for providing sustained power to an electrical grid.
