Lake Resources high-purity “clean” lithium carbonate to be used for first lithium-ion battery test cells at Novonix

Novonix is ​​preparing to begin testing Lake’s lithium carbonate with preliminary cathode precursor lithiation, followed by full pilot-scale evaluation.

Lake Resources NL (ASX: LKE) (OTCMKTS: LLKKF) (FRA: LK1) high purity “clean” lithium carbonate produced from Kachi brines was sent to Novonix Ltd (ASX: NVX) (OTCQX: NVNXF) Novonix Battery Technology Solutions in Nova Scotia, Canada, to produce NMC622-based lithium-ion battery test cells.

Novonix is ​​preparing to begin testing Lake Resources lithium carbonate with preliminary cathode precursor lithiation, followed by full pilot-scale evaluation.

The program will run for four months and the first results are expected in February.

The first samples of Lake’s 99.97% high-purity lithium carbonate, produced from brines from Lake’s Kachi project in Argentina, have been shipped by Hazen Research Inc.

Hazen continues to produce 5 to 6 kilogram high purity carbonate samples using a simple flowsheet from lithium chloride produced in the Lilac Solutions pilot plant module from brines of Kachi.

“Milestone”

Lake Resources Managing Director Steve Promnitz said, “The launch of the Novonix program is an important milestone for Lake and the timeline for delivering first results is on track.

“We are confident that Novonix’s work will clearly demonstrate that lithium carbonate produced from Kachi brines will have the necessary specifications required by Tier 1 battery manufacturers.

“Additionally, demand for such a sustainable and responsible product is growing in North America and Europe as electric vehicle manufacturers seek to strengthen their ESG credentials and the use of gasoline-powered vehicles is phased out.

“Kachi has all the characteristics to meet this new demand at the scale needed.”

Shares were up to 12% higher at A$0.067.

Lithium carbonate test

Novonix Ltd provides high precision battery test equipment to Tier 1 battery manufacturers including Panasonic, CATL, Samsung, SK Innovation, LG Chem, Bosch, Honda and Dyson.

Using Novonix’s pilot cell line, Lake’s high-purity, responsibly-sourced lithium carbonate samples will be used with commercial battery cathode precursor materials to form an NMC622 cathode that will then be processed into NMC622 lithium-ion batteries for testing.

This will allow Lake and its potential partners and customers to make direct and meaningful comparisons of Lake’s lithium product performance in familiar battery chemistries.

Novonix expects the testing process to take at least four months, with first results expected approximately two months after production of the cathode material.

Lake Resources will update the market once the results are available.

Premium price potential

Hazen will continue to produce lithium carbonate, targeting 5-6 kilograms of samples in this run derived from the first 20,000 liters of Kachi brines.

A further 20,000 liters of brine are stored with Lilac, while additional brines are being prepared for transport from site to produce more samples to meet increased demand, given recent positive results.

The high purity lithium carbonate results were obtained via a simple flowchart without any anticipated changes to the operating costs previously forecast in the Kachi pre-feasibility study.

Low impurities are a key factor in determining battery quality as well as price and acceptance of lithium products.

Lake Resources’ high-purity carbonate offers the potential for high prices.
