Dragonfly Energy Holdings Corp., a deep cycle lithium-ion storage battery supplier, has been awarded patent number US11,491,508 by the United States Patent and Trademark Office (USPTO).
The patent is for “systems and methods for dry powder coating layers of an electrochemical cell,” the company said. The patent is a major step forward in the Dragonfly’s mission to provide affordable and effective energy storage solutions, the company said, including the domestic manufacturing of all solid-state battery cells.
“This patent is another significant achievement for Dragonfly Energy,” said Dr. Denis Phares, Dragonfly Energy CEO. “We have been developing dry powder coating processes for lithium-ion battery production for over a decade, and this newly patented process is a key piece of the foundation for manufacturing our all solid-state batteries here in the U.S. Developing a domestically produced battery is critical to the country’s grid stability and our ultimate goal of revolutionizing grid storage.”
The patent adds to Dragonfly’s dry powder coating of lithium-ion battery electrodes, the company said. The powder coating system replaces methods which require a significant amount of time and expensive heavy machinery by forming a particle layer on a substrate through a dry powder coating spray process. According to Dragonfly, the process is groundbreaking and the company said the process will enable the company to significantly reduce space and cost for lithium-ion battery manufacturing.
Dragonfly said the process is integral to scalable production of a non-flammable solution for lithium-ion battery applications.
“Dragonfly’s all solid-state batteries will contain a solid electrolyte rather than liquid, making them lighter, smaller, non-flammable and potentially cheaper to manufacture than conventional battery chemistries,” the company said. “Dragonfly Energy has validated its solid-state technology and is optimizing the cells in preparation for production. The company’s unique solid-state technology is designed to be cost-effective and is expected to allow for highly scalable manufacturing. Unlike many battery manufacturers in the industry today who focus on developing batteries for the EV market, Dragonfly Energy’s products uniquely focus on deep cycle storage for grid, residential and industrial applications.”
