Talga claims “significant breakthrough” in li-ion battery race

Perth company says its graphite anode help delivered 20% higher capacity and 20% higher power in lithium-ion battery cell tests, against the industry standard.


ASX listed material technology company Talga Resources is claiming a breakthrough in its plan to piggyback on the global battery boom, after tests of its graphite anode were shown to significantly boost the performance of lithium-ion battery cells.

Perth-based Talga – which was listed in this June 2017 RE article as one of a new-breed of Australian mining hopefuls – said the promising result was gleaned from tests at independent facility WMG, part of the University of Warwick Energy Innovation Centre.

The tests pitted Talga’s graphite anode material against a current market leading anode graphite product in li-ion pouch cells and found the Talga product delivered 20 per cent higher capacity (total energy), 20 per cent higher power (rate of charge/discharge), as well as 94 per cent first cycle efficiency.

For those wondering, pouch cells are one of three main types of lithium-ion cells used, largely, to make up EV batteries – for example, they’re used in the Nissan LEAF, and in Jaguar’s new I-PACE SUV. See graphic below.

The results, says Talga, show potential for the company’s graphite anodes to beat synthetic and natural graphite standards currently used in the global battery supply chain, “with higher performance, energy, power and life span at potentially lower cost and no decrease in safety.”

They also suggest “clear potential for near term sales” for the company, which is the 100% owner of unique high grade conductive graphite deposits in Sweden, a test processing facility in Germany and in-house product development and technology.

“These results are a highly significant development for Talga,” said managing director Mark Thompson in comments on Tuesday.

“The unique characteristics of our Swedish graphite ore body combined with our proprietary processing technologies produces a li-ion battery with significantly higher power and energy as tested by WMG.

“The company considers that based on the results, Talga’s graphite will set the industry standard for lowering cost of production as it eliminates comparatively expensive industry standard … currently sourced from Chinese and other graphite flake producers.

“The test results and Talga’s unique position in the market create optionality for scale-up development, commercial partnerships and sales of advanced materials in addition to graphene-only products in future.

“Talga’s significant resources positions our energy products division to evolve into a stand-alone battery technology company with exclusive access to a lower cost and unique, high performance battery grade graphite, sourced from our wholly owned deposits in Sweden.”

The company says it is also taking part in advanced product testing with a range of international corporations including industrial conglomerate Chemetall (part of BASF), Heidelberg Cement, Tata Steel, Haydale, Zinergy and Jena Batteries.

Talga’s share price was up more than 6 per cent at the time of publishing, at $A0.78 a share.

    Big, if true.

    What this also highlights is the march towards incremental improvement. Cumulatively it makes a huge difference.

      Yes. Great news if true. It is those incremental improvements over many decades that took the dominant crystalline silicon solar cells from the demonstration in the lab in 1954 to where it is today. I am very optimistic a similar development will occur for battery storage. Only that technologies other than lithium will also have a chance, depending on the application, e.g. home storage vs mobile use.

    There seem to be a lot of broken links on the site at the moment. The Alan Jones sory, BMWs new car etc just leading to 404 errors

    Most ‘new battery technology’ articles you see are mostly hype, with concept cells in the lab that don’t translate well to mass production, but this one looks like a good, solid incremental improvement on four fronts: efficiency, capacity, power and cycle lifetime. That’s the quad-fecta right there,
    The picture is a little confusing since it shows Talga Graphene, which is a very different animal (and graphene anodes are very much research beasts), but the Talga website explains they produce the graphite as a by-product of graphene production.

    Meanwhile, a simple Google search shows that there are significant graphite mining ops in South Australia.
    Whether the graphite will be of suitable quality for li-ion battery anodes remains to be seen, but please, Australia, don’t let this be another bus that we miss.
    Call me cynical, but perhaps there is a case to be made for urging the non coal, non iron ore mining interests to lobby federal politicians to shift their alliegence from moribund coal to the other, emerging big money earners and potential export industries. Show them a reliable source of money, and they are likely to seize it. To the profound benefit of the economy and the climate.
