Leading the “lead is dead” revolution
Dragonfly Energy’s cutting-edge technology is enabling the widespread conversion to green, renewable energy. We produce batteries that solve today’s lead-acid problem and are creating next-generation solid-state batteries to address tomorrow’s energy storage needs.
Conventional Li-ion Cell Production
Producing lithium-ion battery cells is a messy and expensive process. Nasty solvents are required for dissolving the polymer binder during electrode coating. These solvents must be removed and reclaimed prior to cell assembly using power-hungry ovens and vacuum systems. It is a time-consuming process that ultimately drives up the cost of energy storage.
Dragonfly has set out to develop cleaner and less wasteful processes to create lithium-ion batteries.
Our focus is not the cell chemistry, but rather the manufacturing process. We have developed a dry, solvent-free process whereby electrodes are rapidly grown one particle at a time. We can produce conventional cathodes and anodes with no solvents, no ovens, and no vacuum.
We produce double-coated anodes and cathodes, composed of any chemistry, with a fraction of the binder, in a reel-to-reel fashion. Powder in, cell out. It’s that simple. And cycling behavior is not compromised.
Dragonfly Energy has a unique position in the industry, as we have taken control of the manufacturing and shipping processes. From design and assembly to customer service, we continue to put the consumer first by offering the best technology on the market – with the continued service to back it up.
But we did not stop there, enter a new generation of Li-ion batteries…
All Solid-State Batteries (ASSBs) are batteries with a solid electrolyte, instead of a liquid electrolyte. ASSBs are lighter, smaller, completely non-flammable, and, if mass-produced, potentially cheaper.
Dragonfly has validated its solid-state technology and is currently optimizing the cells and preparing for production. Dragonfly’s unique solid-state technology is purpose-designed for cost-effective, highly scalable manufacturing. Our patented process allows us to rapidly grow the electrodes, interfaces, and solid electrolyte layers one particle at a time. With no solvents, no ovens, and no vacuum. Just instant cell production.
We believe that we have found a way to drop the price of energy storage globally. While this is one step in the right direction, we imagine a future where Dragonfly’s smart storage solution will allow for less reliance on the power grid with ample access to back up power by distributing energy.
