Lake Resources NL at record high as Novonix tests show lithium carbonate performs better than commercially available battery-grade lithium carbonate

0

Lake’s high-quality product provided better capacity retention and better electrochemical behavior in coin cells compared to commercially available product from Tier 1 producers.

Lake Resources NL (ASX:LKE) (OTCMTS:LLKKF) hit a new all-time high by confirming positive initial test results from Novonix Ltd (ASX:NVX) (OTCQX:NVNXF) showing its lithium carbonate performs better than commercially available battery-grade lithium carbonate in lithium-ion battery cells.

Testing revealed that Lake’s high-quality product provided better capacity retention and electrochemical behavior in button cell batteries compared to product commercially available from Tier 1 producers.

Shares jumped 23.5% in early trading to reach AU$0.475, a new all-time high, while the company’s market capitalization sits at around AU$390.4 million.

Other tests

Larger scale testing will be conducted using batch synthesis to demonstrate repeatability, homogeneity, and cell characterization and validation in complete lithium-ion bagged cells, within lineage facilities. Novonix pilot-scale cell phones in Nova Scotia, Canada.

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

Novonix expects this testing process to take a few months and will notify the market as soon as the results are available.

“Excellent position to progress”

Lake Resources Managing Director Steve Promnitz said, “Novonix’s results demonstrate the high quality of Lake’s high-purity lithium in batteries and future results should reinforce the initial results.

“This gives EV manufacturers and battery manufacturers confidence in the quality of Lake’s products, which is especially important given the growing demand for a high-purity product.”

“Lake is advancing the Kachi DFS amid an increasing focus on sustainability and the need for a responsibly sourced product suitable for the supply chains of major electric vehicle manufacturers.

“With increased investor and industry engagement, Lake is in an excellent position to advance our product and unlock increased shareholder value.”

Test results

Novonix received commercial samples of NMC622 hydroxide precursor from Tier 1 producers, as well as high purity 99.97% lithium carbonate samples from Lake, for direct comparison around the world reality of Lake’s product in NMC622 batteries and its suitability for the nickel cathode sector.

The cathode material was tested for electrochemical properties using half cell tests.

The powders were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD) to understand morphology and phase purity. XRD showed no impurities.

Lake’s lithium carbonate was used as is and also ground, but no appreciable difference was noted in the resulting NMC powders when synthesized.

NMC622 was mixed with conductive carbon and binder, cast onto an aluminum foil current collector, dried, punched, and assembled into a lithium-ion battery half-cell which yielded similar voltage profiles, a better capacity retention and better electrochemical behavior compared to commercially available product from Tier 1 producers.

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