Firebird Metals has reported significant improvements in its battery precursor materials, including a 46% reduction in sulphur content. The company also achieved a tap density of 1.36 g/cm3 for its manganese-rich and nickel-manganese hydroxide products.
Why it matters
Reducing sulphur as an impurity helps maintain battery performance, while higher tap density enables cathodes to store more energy within the same volume. These technical gains are critical for improving overall battery efficiency and energy storage capacity.
The firm achieved a final sulphur content of 610 parts per million in its manganese-rich materials. This level represents a 46% reduction in impurities compared to prior testing.
The players
Firebird Metals
This ASX-listed company specialises in the development of manganese battery materials for various industrial applications.
General Motors
A major multinational automotive manufacturer currently working with partners to develop advanced LMR battery technology.
