Dragonfly Energy Holdings Corp. announced on June 15 that it has received a notice of allowance from the European Patent Office for a patent application related to its dry electrode manufacturing technology, a development the company said strengthens its intellectual property portfolio and supports its efforts to commercialize next-generation battery technologies.
The patent application, titled “Systems and Methods for Dry Powder Coating Layers of an Electrochemical Cell,” covers aspects of Dragonfly Energy’s proprietary dry electrode manufacturing platform.
According to the company, the technology uses dry powder coating to create key layers within an electrochemical cell, including electrode, separator, and solid-state electrolyte layers.
The allowance marks an expansion of the company’s patent protection in Europe and adds to its broader strategy of developing and commercializing advanced battery technologies. Dragonfly Energy said the technology is intended to support scalable, solvent-free battery manufacturing while also contributing to the development of all-solid-state battery cells.
“This European allowance expands the global reach of our intellectual property portfolio and strengthens protection around the dry electrode technology central to our long-term cell manufacturing strategy,” said Dr. Denis Phares, Chief Executive Officer of Dragonfly Energy.
“As we advance our all-solid-state battery development, we believe securing such patent rights in key markets will strengthen our position for future commercialization opportunities worldwide.”
The company stated that securing patent rights in Europe is part of its effort to expand its presence in global energy storage markets. Dragonfly Energy’s dry electrode platform is designed to support multiple battery chemistries and facilitate the future deployment of nonflammable, all-solid-state battery cells.
Dragonfly Energy, headquartered in Reno, Nevada, operates as a lithium battery technology company involved in battery cell manufacturing, battery pack assembly, and system integration. Through its Battle Born Batteries brand, the company supplies lithium battery products to original equipment manufacturers and retail customers across multiple industries.
The announcement comes as battery manufacturers continue investing in technologies aimed at improving manufacturing efficiency, reducing environmental impacts, and enhancing battery safety.
Dry electrode manufacturing has attracted industry attention because it can reduce or eliminate the use of solvents traditionally required in battery production, potentially lowering production costs and simplifying manufacturing processes.
For professionals in the RV, caravan, glamping, and outdoor hospitality sectors, developments in battery technology may have long-term implications for energy storage systems used in recreational vehicles, off-grid accommodations, and campground infrastructure.
Advances in solid-state battery technology could eventually contribute to higher energy density, improved safety characteristics, and broader electrification options for operators seeking reliable power solutions in remote or off-grid environments.
The European patent allowance represents another milestone in Dragonfly Energy’s ongoing efforts to protect and commercialize its battery manufacturing technologies as it continues to pursue the development of next-generation energy storage products.
