Nachu anode product

Magnis has produced a 99.99% purity coated spherical graphite anode product from Nachu graphite using existing commercial scale technology and facilities in North America.
The production of this anode product did not require any chemical purification phase with acid treatment (HCl/HF). The anode product also delivered outstanding battery cell test results, with favourable performance across key criteria relative to leading Chinese natural and synthetic graphite anodes.
The ability to achieve this outcome is driven by the particular crystalline structure and low in-situ impurities within the Nachu mineralisation.
By alleviating the need for intensive chemical or thermal purification to be undertaken in China (where the overwhelming majority of such graphite processing occurs), Magnis has presented the viability of an alternative supply chain to that which currently exists. It also delivers the clear potential for

Magnis to be amongst the lowest cost anode producers with one of the smallest environmental footprints globally. The use of existing technology and commercial facilities is also highly significant in that it delivers replicable results that could be scaled up quickly at low cost in North America and other geographic regions in close proximity to a range of different end users.
Latest battery test results
The most recent lithium-ion battery tests on Nachu anode product
(>99.95% coated spherical graphite) delivered the following results:Tap density = 1.21 g/ccCompressed density = 1.75 g/ccBET = 1.908 m2/gTotal Ash < 0.05 %First cycle efficiency = 95%First charge capacity = 354 mAh/gThese results see the Nachu anode product compare favourably with the leading Chinese natural and synthetic graphite anode products.The results demonstrate the ability of Magnis to produce battery grade anode material from Nachu graphite feedstock, without the use of chemicals and toxic acids and utilising solely existing commercial scale technology.

This important milestone illustrates the viability of a greener and lower cost supply chain for graphite anodes in lithium-ion batteries.

Looking forward to Nachu project to get underway.
