DPMG provides a method for synthesizing highly engineered particles through the consolidation of fine materials, that may otherwise be waste, into particles that can be tens of microns and suitable for use in lithium-ion batteries. The recent publication outlines methods of making spherical graphite for use in lithium-ion batteries with 100% yield where current methods have significant yield losses which increase the cost of manufacturing.
Patent applications protecting the DPMG process have been filed by
NOVONIX Managing Director,
In addition to the ability to make graphite particles with no waste, the technique can be used to synthesize cathode materials such as Li[Ni1/3Mn1/3Co1/3]O2 (NMC) through a dry process with no waste water or materials. A typical facility producing 6,500 kg of NMC per day can generate 99,000 L/day of wastewater while also generating fine particle waste resulting in both negative economic and environmental impacts.
In the Li-ion battery field, I believe this technology shows great promise for reducing battery costs and increasing battery performance; while simultaneously reducing the waste and environmental impact of battery production."
The results are receiving praise from the industry, including fellow Dalhousie Professor and NSERC TESLA Canada Industrial Research Chair, Prof.
The ability to be able to synthesize both state-of-the-art positive and negative electrode materials with this method is truly exciting.
I believe that the onion-like morphology of natural graphite particles made from what would normally be considered waste is extremely important and could potentially lead to the best and least expensive graphites for lithium-ion cells. I believe that the ability to synthesize appropriately-sized dense particles of NMC and other positive electrode materials in a completely waste-free process, unlike the current methods used today by industry, has huge potential.
I congratulate the Obrovac team for their outstanding and innovative work done in the Chemistry department at

"DPMG is an incredible discovery as a method to produce battery active materials for both the anode and cathode while generating no waste. There are immediate opportunities to utilize this technique within our PUREgraphite business, as well as the ability to pursue unique cathode material synthesis methods that can decrease the cost of cathode active material such as NMC.
We are excited to continue to work with
