FYI Resources (FYI) and EcoGraf (EGR) have announced positive results for their enhanced high purity alumina (HPA) anode coatings development program.
The two companies say they are pleased with the results and are providing product samples to partners and battery manufacturers. The objective of the program is to develop a commercial innovative active anode material in Western Australia by further value adding its materials for the lithium-ion battery market.
The anode coatings development program is being conducted at a US-based battery materials research facility using EcoGraf HFfree spherical graphite (hdBAM) and FYI’s ultrafine 4N HPA (99.99 per cent HPA) to generate HPA-doped coated spherical graphite.
Electrochemical performance of the coated anode and FYI HPA-doped coated anode was undertaken in an industry standard lithium-ion coin cell.
The program successfully produced coated spherical graphite and enhanced HPA-doped coated spherical graphite that has met the technical specifications required by leading battery manufacturers.
When compared to the current industry anode material from China, the lithium-ion coin cell electrochemical performance achieved better results.
The industry market anode has a reversible capacity of 355 milliampere hours per gram (mAh/g) with irreversible first cycle loss of seven per cent.
However, the companies’ coated anode has a reversible capacity of 353.4 mAh/g with irreversible first cycle loss of just 5.2 per cent. The companies said this was an excellent result and makes the coated anode a “superior performing lithium-ion anode material”.
In saying that, the HPA-doped coated anode performed even better against the industry standard. Specifically, the reversible capacity was measured at 362.7 mAh/g and the first cycle loss was 4.5 per cent.
“The initial FYI coated anode testwork results are outstanding and demonstrate the potential of further development on this project,” FYI Resources Managing Director Roland Hill said.
“We are particularly encouraged by the out-performance of our developed anode technology In relation to the current market leader. With our partner Ecograf, we will continue the development of this exciting technology and its growing application into the e-mobility sector.”
FYI was up 10.3 per cent with shares trading at 32 cents and EcoGraf was up 12.4 per cent to 68 cents at 12:45 am AEDT.
