International Graphite
Investor Insight
International Graphite’s mine-to-market strategy, leveraging its compelling graphite resource, places the company in a strategic position to become an important player in the development and expansion of Western Australia’s battery supply chain.
Overview
International Graphite (ASX:IG6) is a front-runner in the global graphite industry and is aiming to be one of the first new graphite producers.
The company’s vision for a complete mine-to-market supply chain in Western Australia leverages the state’s global reputation as a secure, reliable and technically advanced resource jurisdiction.
Primary focus is the production of active anode materials for lithium-ion batteries to address growing global demand and the forecast shortage looming for allied markets, particularly the US, Europe, Korea and Japan.
Since listing on the ASX in 2022, the company has made rapid headway in the development of two major assets – a planned graphite mine at Springdale and downstream processing facilities at Collie.
The company has been awarded AU$13.2 million in grants from Australian state and commonwealth governments in recognition of its significance to the development of Australia’s sovereign battery minerals capability.
International Graphite also secured a $4.5 million grant funding from the Western Australian Government to construct the first purpose-built commercial graphite micronising plant. About $2 million will be applied towards the ~3,000 tpa micronising facility to be built in Collie at an estimated capital cost of $4 million and the remaining $2.5 million will be applied to expand the facility and at least double capacity (Stage 2).
In addition, the Western Australian government has further earmarked AU$4 million from the Investment Attraction Fund's New Energies Industries Funding Stream to support the progression of the Springdale graphite project and the development of the Collie Processing Facility.
Market demand
Market attention worldwide is swinging to graphite which is essential for global decarbonization and fast becoming one of the most politically contested of all the critical battery minerals. The graphite market is projected to reach US$24.21 billion by 2031 driven by a CAGR of 5.20 percent.
Graphite is flexible, conductive, heat and corrosion resistant. For decades it has been used to manufacture everything from ceramics and lubricants to plastics and steel.
It is also a major ingredient in batteries of all kinds, making up 95 percent of the active anode in lithium-ion batteries which are the gold standard for electric vehicles, renewable energy storage and advanced medical, defense and aerospace devices.
Of all the components in a lithium-ion battery, the biggest volume is in graphite. It can take 50 to 100 kilograms of graphite to make a single EV battery – up to 10 times more graphite than lithium.
Currently, China supplies over 80 percent of the world’s processed graphite, so its decision to restrict exports to western customers came as a shock in late 2023.
Western nations are scrambling to find alternative supplies to meet existing commitments – and new supplies to meet the shortage of battery materials forecast in the next five years.
With limited graphite sources of its own, and limited prospects in the near term, the US is leading the way, closely followed by Europe, offering unprecedented incentives to fast-track graphite supply from reliable domestic and allied sources.
Company Highlights
- International Graphite (ASX:IG6) is developing a sovereign mine-to-market graphite supply chain in Western Australia, incorporating a graphite mine at Springdale, near Ravensthorpe on the south-coast, and downstream processing facilities in Collie, 200 km south of Perth.
- Primary focus is the production of active anode materials for lithium-ion batteries to address growing demand and a forecast shortage in allied markets, particularly the US, Europe, Korea and Japan.
- The 100 percent owned Springdale Graphite Project is one of the largest in Australia, with a current mineral resource estimate of 49.3 Mt @ 6.5 percent total graphitic content (TGC).
- Now in the final stages of feasibility and permitting, Springdale will host a multi-decade mine and concentrator operation ensuring a secure, reliable feed of graphite concentrates for value-added processing.
- Less than 10 percent of the tenement area and 20 percent of initial geological targets have been drilled indicating enormous potential for future resource expansion.
- In Collie, the company has established Australia’s first graphite R&D and downstream processing facility comprising pilot scale graphite micronizing and spheroidizing and qualification-scale graphite micronizing equipment. The facility has achieved independent ISO 9001 quality assurance certification, the most globally recognized standard for quality management systems.
- Design is well advanced and funding is in place for a commercial-scale micronizing plant due to be constructed at Collie in 2025. It will supply graphite products for traditional manufacturing and industrial applications, including lubricants, plastics and polymers.
- Australian state and commonwealth governments have awarded grants totalling AU$13.2 million, to fast-track the business in recognition of its importance to the nation’s critical minerals capability.
- Purification test work done on Springdale concentrates achieved 99.99 percent purity - well above highest purity anode material product specification of 99.97 percent.
- The company has an expert management team, with proven technical credentials, is committed to rigorous environmental, social and quality standards, and has strong government and community support.
Key Projects
Springdale Graphite Project
International Graphite owns 100 percent of the Springdale graphite project in the established mining centre of Hopetoun/Ravensthorpe, on the south coast of Western Australia.
Springdale is one of the largest graphite deposits in Australia and was named Discovery of the Year in the respected 2023 Prospect Awards.
Following an extensive drilling campaign in 2022-23, the resource estimate increased by more than 240 percent to 49.3 Mt @ 6.5 percent total graphitic content (TGC). This is expected to grow in the future as only 10 percent of the tenement area and 20 percent of initial geological targets have been drilled to date.
Springdale is the site of the company’s planned graphite mine which will provide a consistent and reliable feed of graphite concentrates for downstream processing and give the company full control of its supply chain. A scoping study, released in January 2024, showed the planned open pit operation would be globally cost competitive with a long, multi-decade mine life.
The planned mine is on cleared farmland, with easy access to established roads and infrastructure. Permitting activities are well underway and two mining leases have been granted. The regional community relies heavily on the mining sector and has applauded moves to establish a new operation in their area.
Metallurgical testwork on Springdale concentrates, completed by specialist testing laboratories in Australia and overseas, shows the high-grade, fine flake Springdale ore is ideally suited for the production of battery anode material. Bench scale micronising, spheroidising and purification testwork on graphite concentrates were undertaken by industry specialists ProGraphite GmbH and produced outstanding results. The tests produced two spherical graphite products – SpG11 and SpG18 – with a yield of up to 76 percent. Purification testwork reached 99.99 percent graphite purity – well above the usual specification for battery anode material at 99.97 percent.
International Graphite’s vision for a complete mine-to-market business is designed to achieve maximum value from its Springdale natural graphite resource and is closely aligned with the Australian government's critical minerals strategy and the Western Australian government's vision to establish new world-class industries in Collie.
Collie R&D and Processing Facility
International Graphite’s Collie R&D and Process Facility is a first for Australia and a key link in the company’s mine-to-market strategy.
Backed by an ISO 9001 quality assurance certificate, the Collie facility is home to pilot scale graphite micronizing and spheroidizing equipment, thermal purification equipment, and a qualification-scale micronizing plant that is currently producing sample products for assessment by potential customers in the industrial manufacturing and battery markets.
As well as being widely used in industrial products such as lubricants, plastics and polymers, micronized graphite is a critical conductive additive in battery cathodes. It is also the first stage in the production of active anode material for lithium-ion batteries.
International Graphite plans to expand micronizing at Collie to commercial scale with construction scheduled in 2025. At the same time, it is progressing plans for a separate advanced battery anode material manufacturing facility. The plant design will be tailored to process Springdale graphite concentrates.
Located 450 km by road from Springdale, and close to major export ports, the regional township of Collie is the centre of Western Australia’s electricity generating infrastructure.

Altech Batteries
Investor Insight
An innovative technology that promises positive economics places Altech Batteries in a compelling position to take advantage of a booming batteries market driven by global electrification and clean energy transition.
Overview
Altech Batteries (ASX:ATC,FRA:A3Y) is a battery technology company focused on commercialising the revolutionary CERENERGY® Sodium-Chloride Solid State (SCSS) Battery, destined for the renewable energy grid storage market. The SCSS Battery does not require lithium, cobalt, copper, graphite or manganese, bypassing these high-demand and expensive minerals, and leverages a novel sodium-chloride (common table salt) technology to produce a more durable and longer-lasting battery. This new battery uses cheaper and readily available sodium rather than the more scarce, costly and risky lithium. Altech is headed by an experienced team who understands what it takes to bring transformative technology to market.
That's not all Altech has going for it, either. Unlike other energy storage options, the company's new SCSS Battery technology promises to solve many issues associated with traditional lithium batteries, including fire and explosion risks, manufacturing costs, operating temperature ranges and lifespans.
The reality is simple: Lithium-ion batteries have been susceptible to fire and explosions and have even malfunctioned in certain temperatures – all critical issues that must be solved to ensure long-term sustainability.
CERENERGY® batteries solve these challenges. For example, they do not contain any volatile flammable electrolytes or plastic separators, and they use solid-state ceramic tubes. Simply put, the thermal runaway problem that's plaguing lithium-ion batteries is not possible with Altech's new battery technology.
Altech has a joint venture agreement with the German government battery institute Fraunhofer IKTS, which has been developing the CERENERGY® battery over the past eight years and invested over €35 million (~US$39.7 million) in research and development. Altech is commercialising the technology by providing expertise and resources to build a new 120-MWh-per-annum plant in Saxony, Germany, on Altech's land.
In 2024, the pilot line at Fraunhofer IKTS in Hermsdorf, Germany underwent a comprehensive redesign to facilitate the manufacturing of two ABS60 60 kWh battery prototypes. Innovative tools and machinery have been developed and implemented specifically for producing the battery cells required for the 60 kWh prototypes. The first ABS60 battery prototype is now online and operating successfully, passing all physical tests with great results.
As of April 2025, rigorous individual cell stress-testing conducted by Fraunhofer IKTS has confirmed the safety and operational robustness of the CERENERGY® technology under extreme conditions, including over-discharge, overcharge, high C-rates and elevated temperatures of up to 400°C.
Altech Batteries also released the results from a definitive feasibility study (DFS) conducted for the CERENERGY® project with an annual capacity of 120 MWh GridPacks. DFS showed a capital cost estimated at €156 million (US$170.15 million) with excellent project economics.
The CERENERGY® project is being developed by Altech Batteries GmbH (ABG) with 75 percent interest and joint venture partner Fraunhofer IKTS with 25 percent interest. ABG is 75 percent owned by Altech Batteries and Altech Advanced Materials AG (FSE).
Altech Batteries has executed several offtake agreements in 2024:
- Zweckverband Industriepark Schwarze Pumpe will purchase 30 MWh of energy storage capacity annually, consisting of 1 MWh GridPacks, for the first five years of production.
- Referenzkraftwerk Lausitz GmbH (RefLau), a joint venture between utility companies Enertrag SE and Energiequelle GmbH. RefLau will purchase 30 MWh of CERENERGY® energy storage capacity in the first year, then 32 MWh per year thereafter for the next four years of production. It was further agreed that Altech will purchase green electricity at competitive prices directly from the partners in the region for the planned production plant.
- Axsol GmbH (Axsol) is a leading, award-winning integrated renewable energy solutions provider. Altech has entered into an exclusive distribution agreement with Axsol to supply the western defence industry with CERENERGY® battery technology.
To address funding requirements, the company has executed a binding Bond Note Subscription Deed with major shareholder Deutsche Balaton AG, under which it candraw down up to €2.5 million (US$2.8 million) in cash in the form of interest-bearing Bearer Bonds. Altech is also in the process of selling its land in Johor to provide additional funding.
