Transportation Storage

The University of Maryland (UMD) will increase the charge/discharge-rate capability, energy density, and operating temperature window of solid-state lithium metal batteries.

Tyfast Energy will develop a High sYmmetric PowER (HYPER) Battery that leverages a novel oxide-based anode and high conductivity electrolyte that has been demonstrated to perform well over a wide temperature range. This new HYPER combination of electrode material and electrolyte chemistry will enable a high-energy density, < 6 minutes ultrafast-charging battery with > 3,000 cycle life.

The Ohio State University will develop a high-power battery technology featuring a high entropy oxide (HEO) anode that can tolerate rapid charging while demonstrating longevity far beyond the current state-of-the-art lithium-ion cells. Ohio State will (1) address manufacturing challenges in achieving large-format, commercial-quality cells, (2) enable drop-in compatibility with existing battery components, and (3) optimize battery performance for cold temperatures.

Sylvatex will use a low-cost, high-yield, and simplified continuous approach to synthesize lithium iron phosphate iron (LFP) based cathode materials for lithium-ion batteries (LIBs) where the reactants flow and mix continuously. Sylvatex’s proprietary nanomaterial platform has already demonstrated a significant breakthrough in synthesizing cathode materials for LIBs.

The University of Maryland (UMD) recently invented an elegant and scalable molecular engineering technique for fabricating a cellulose nanofiber (CNF)-based SSE that could overcome many of these problems. Unlike current SSEs, the CNF-based SSE uses natural materials, is easy to process, and is compatible with conventional coating processes. It can also be inexpensively manufactured due to its low material cost and paper-like roll-to-roll manufacturing, both as standalone electrolyte films and the electrolyte portion of solid-state cathodes for lithium ion and metallic lithium cells.

The University of Houston will develop a battery that will match the energy and power densities of lithium-based batteries while excluding lithium, nickel, and cobalt. The proposed battery will substitute lithium-based anodes with energy-dense and abundant magnesium, of which the U.S. has virtually unlimited reserves. Organic materials obtained from oil refineries and biorefineries will replace conventional cathodes based on transition metals, thereby eliminating any requirement for nickel or cobalt.

The University of Michigan aims to develop a new type of battery separator that can completely stop dendrite formation. The key innovation is a special mechanism that suppresses dendrite growth with the University of Michigan’s wet-process-synthesized film as a separator or coating. When an electrode surface starts to lose stability upon lithium deposition, any protrusion will cause deformation of the film, generating a local shielding effect that deflects lithium ions away from the tip of the protrusion. This slows down the tip growth and makes the lithium metal surface flat.

Colorado State University and its partners—ION Clean Energy, Worcester Polytechnic Institute, and Bright Generation Holdings—will develop a thermal energy storage system with flexible advanced solvent carbon capture technology. The system aims to decrease the levelized cost of electricity for natural gas-fired combined cycle (NGCC) power plants to <75 $/MWh while simultaneously capturing >95% of CO2 emissions when operating in highly VRE penetration markets. The team's approach uses a novel and low-cost heat-pump thermal storage system.
