    Test work on Anson Resources lithium products points to longer battery life

    Anson Resources Limited (ASX: ASN) has reported that test work carried out by NOVONIX Battery Technology Solutions on its lithium products indicate longer battery life than a comparable commercial product.

    NOVONIX compared cathode powder synthesised using commercial metal hydroxide and lithium precursors to Anson’s lithium product sourced from its Paradox Brine Project in the United States to provide real-world comparisons.

    Cells went through formation, ultra-high precision coulometric cycle testing, long-term cycle performance testing, and high temperature storage tests. The test work consisted of the cells being charged and discharged over hundreds of cycles.

    The results reinforce previous findings by NOVONIX on Anson’s cathode material, which delivered similar results.

    Anson product out-performs commercial alternative

    NOVONIX delivered positive results from test work completed on high performance lithium-ion batteries using Anson’s high-purity lithium carbonate & lithium hydroxide.

    Anson reports that its 99.9% purity lithium carbonate product out-performed the commercial product blend, with results including:

    • similar or better first-cycle efficiency and lower gas production during formation cycles
    • less capacity loss and lower impedance growth during NOVONIX UHPC & LT cycling testing
    • lower voltage drop and gas production after STO, indicating possible higher cathode stability than reference material

    Meanwhile, Anson’s lithium hydroxide performed similarly to the commercial product in long-term cycle experiments, with cycle testing ongoing.

    Higher battery life-span

    Test work indicated that Anson materials retained more available capacity after the first formation cycle, and importantly, showed lower capacity losses during ultra-high precision coulometric testing.

    These attributes are considered key to potential battery manufacturers as they provide longer battery lifespan.

    “In layman terms the test work performed on Anson lithium indicate a longer battery life”

    Management comments

    Anson Resources Executive Chairman and CEO Bruce Richardson said: “The results from NOVONIX’s test work clearly demonstrates that the lithium carbonate and lithium hydroxide produced from the Paradox brines have the necessary specifications that Tier 1 battery makers may require. In layman terms the test work performed on Anson lithium indicate a longer battery life.

    The results confirm and enhance the results for the earlier test work conducted by NOVONIX on behalf of Anson. The purity of the Anson product provides it with a performance advantage over existing commercial products which is expected to attract lithium-ion producers that are aiming to provide a high-performance product. As well, demand for such a sustainably-produced and responsibly-sourced product is growing in North America and Europe as electric vehicle makers look to bolster their ESG credentials.”
