Talga Resources Ltd (ASX: TLG) achieves the ‘outstanding’ freezing temperature performance in the commercial development test of its anode product. The news sent the stock price to edge up by 0.855% to last trade at $0.590 on 21 March 2019.
In the announcement dated 21 March 2019, Talga Resources announced that it has received outstanding low-temperature test results from its engineered graphite anode product for lithium-ion (Li-ion) batteries, Talnode™-C.
Talga’s Talnode-C has outperformed market leading commercial anode products with the retention of 100% capacity and 100% cycle efficiency at freezing temperature (0°C). In freezing conditions Li-ion batteries usually suffer lower capacity retention and cycling efficiency, causing shorter runtime of devices such as laptop computers and mobile phones, or shorter driving range of electric vehicles.
Mr Mark Thompson, Managing Director of Talga, stated “These results show Talnode-C has the potential to solve problems that have long challenged Li-ion batteries in cold weather applications, where conventional graphite anodes struggle or fail to perform. This is a further demonstration that Talga’s anode products made from our high-grade graphite deposit in Sweden, using wholly owned process and refining technology, have exciting potential in the fast-growing Li-ion battery market.”
The results are the outcome of a new performance test conducted at a leading Japanese battery institute under which Li-ion batteries using Talnode-C were tested for their performance at varied temperatures including freezing conditions.
The development addresses the bleak performance of Lithium-ion batteries when used at freezing temperature. To have a better technical understanding, it can be said that the lithium ions aren’t efficiently captured by the anode under temperatures approaching freezing (0°C). Instead, many lithium ions are reduced to lithium metal and coat the surface of the anode, a process called lithium plating, resulting in less lithium available to carry the flow of electricity. As a result, the battery’s capacity and cycle efficiency drops and this translate to poorer performance.
In the tech-driven age, the eco-friendly goals are rapidly approaching the use of electric vehicles across the globe. The use of lithium-ion batteries remains at the heart of it! The recent studies have estimated that around 400,000 tonnes of lithium will be required for use in an electric vehicle by 2025.
It creates a lot of opportunities for Talga to capture the anode product market by offering such a product that has the proven potential to deliver outstanding performance even at freezing temperature for lithium-ion batteries.
Currently, technology materials developer, Talga, is rigorously accelerating the development of Talnode-C through commercial validation processes at multiple commercial partner facilities and independent battery institutes in Asia, USA and Europe.
The company stated that moving forward market validation of the TalnodeTM product range, particularly the flagship Li-ion anode product Talnode-C, continues as Talga works to incorporate the development of its new class of high-performance graphitic carbon anode products into its long-term business strategy. Further, it expects that Talnode-C, a fully engineered and formulated an active anode-ready product to be marketed directly towards Li-ion battery manufacturers, will form the foundation of a near-term commercialisation opportunity for the company’s large-scale development of the Vittangi graphite project in Sweden.
