Rapid Surface Graphitization of Carbon Anode for In Situ Regeneration of Batteries
HighT-Tech will develop ultrathin and compact protective coating material for the graphite surface using ultrafast high-temperature
sintering. The technology would enable in situ lithium iron phosphate/graphite battery cell regeneration and lengthen the lifetime.
Since lithium iron phosphate/graphite cells are relatively low-cost to produce, recycling the cells is prohibitively expensive. In this case, generating the battery, which recovers or restores the battery’s capacity, could be a more efficient and sustainable solution. This technological advancement would support the expanding $15 billion lithium iron phosphate/graphite battery market.

HighT-Tech Scale-up the UHS Manufacturing of Solid-State Batteries
HighT-Tech is participating in a new $4 million DOE-EERE project, teaming with Argonne National Laboratory (ANL) and Oak Ridge National Laboratory (ORNL) to scale up the UHS manufacturing of oxide-based electrolytes and solid-state batteries, which are intrinsically nonflammable.
The project will transform the current batch process for fabricating and sintering solid oxide-based electrolytes into a continuous process. This project will also integrate the NMC cathode, electrolyte, and anode into full cells and scale them up from the current button cell (≤10 mAh) to ≥ 1 Ah and ≥350 Wh/kg.

New Environmental-Thermal Barrier Coatings for Ultrahigh Temperature Alloys
HighT-Tech is participating a new ARPA-E project with UMD to leverage a newly invented, ultrafast high-temperature sintering (UHS) method to perform fast exploration of new environmental-thermal barrier coatings (ETBCs) for 1300°C (2372 °F)-capable refractory alloys for harsh turbine environments. UHS enables ultrafast synthesis of high-melting oxide coatings, including multilayers, in less than a minute, enabling rapid evaluation of novel coating compositions. By using UHS with fast-fail tests and modeling and analytics tools, the team will be able to explore hundreds of compositions and coating architectures to design and optimize 1700°C (3092 °F)-capable ETBCs with different layer sequences, thicknesses, porosity levels, and novel compositions.

Pipe-in-Pipe by Rapid, Continuous, Smart Alloy Coating
HighT-Tech is participating a new ARPA-E project with UMD to develop a smart alloy coating for use in pipe-in-pipe configurations with the patented high-temperature sintering process.
A novel smart alloy coating is rapidly sintered with a high-temperature Joule heating bar directly from the alloy powders in approximately 10 seconds. The coating can be scaled to meet commercial market demands due to its high sintering density, mechanical strength, and self-healing properties.
