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.
We know how the process has always been. That’s why we’ve set out to develop cleaner and less wasteful processes to create lithium-ion batteries. The smaller the footprint, the better. At Dragonfly Energy, our long-term goal since the founding of this company has always been sustainability. We’ve worked tirelessly to create and produce a safe product to get people out there.
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:
Here at Dragonfly Energy, we are always innovating. We have the results and processes to back it up. No smoke and mirrors – just real science and forward-thinking technology.
And now, the time is ripe for a new generation of Li-ion batteries. Perhaps you have heard the hype surrounding All Solid State Batteries (ASSBs) – batteries with a solid electrolyte, instead of a liquid electrolyte. The hype is warranted because ASSBs are lighter, smaller, completely non-flammable, and potentially cheaper. “Potentially” is an important caveat here, because nobody seems to focus on the actual mass production of these types of cells – which is critical to the final cost to consumers.
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.
Our research team is continuing to refine this process and find new, original ways to utilize ever-evolving technology.
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 homeowners can power their off-grid system with our renewable and scalable energy storage banks. A fraction of the weight, none of the toxic components, all of the freedom.
