The most important part of a battery is the part you can’t see. For years, the lithium-ion cells powering our cars and grids have relied on graphite for their anodes, the negative electrode that stores lithium ions. It’s stable, but it’s also a bottleneck. Graphite’s theoretical energy density is a known ceiling, and the industry has been hunting for a material to break through it. Silicon, which can hold about ten times more lithium, has long been the obvious candidate. The problem is that silicon swells and cracks when it charges, a destructive party trick that has kept it out of commercial cells for over a decade.
Sicona Battery Technologies, a startup from Wollongong, Australia, thinks it has a recipe that works. Its core product is SiCx, a silicon-carbon composite powder designed to be mixed into the anode slurry of a conventional lithium-ion battery. The company claims its material can increase cell energy density by 20% compared to graphite-only cells, a jump that translates directly into longer range for electric vehicles or more compact storage for the grid [Sicona, retrieved 2026]. More interestingly, Sicona says its process does not rely on silane gas, a costly, hazardous, and emissions-intensive feedstock common to other silicon anode approaches [Sicona, retrieved 2026]. It’s a bet on incremental improvement with outsized impact, sold not as a whole new battery, but as a drop-in ingredient for an existing, trillion-dollar manufacturing machine.
The wedge: a powder, not a cell
Sicona’s commercial strategy is elegantly pragmatic. It is not trying to build a better battery cell from scratch. Instead, it is selling a powder,its SiCx composite,to cell manufacturers like Panasonic, LG Energy Solution, and Samsung, who have reportedly been evaluating samples from Sicona’s pilot plant [Perplexity Sonar Pro Brief]. The pitch is one of compatibility and de-risked adoption. Battery gigafactories represent some of the largest capital investments on the planet; convincing them to swap out a single material supplier is a far easier lift than asking them to redesign their entire production line.
This materials-focused wedge is reflected in its investor base. The lead backer in its A$22 million Series A in June 2023 was Himadri Speciality Chemical, an Indian producer of advanced carbon materials [Business News Australia, June 2023]. In May 2025, Himadri doubled down with a A$15 million follow-on investment that came with a strategic partnership and an exclusive license to manufacture SiCx in India [Region Illawarra, May 2025]. For Sicona, it’s not just capital; it’s a built-in route to a massive future market and a partner with deep expertise in scaling chemical production.
Funding a path to tonnes
The capital stack tells the story of a company moving from lab to factory. After early seed funding, the A$22 million Series A was for advancing work in both Australia and the United States [PR Newswire, June 2023]. The recent A$45 million grant from the Australian Renewable Energy Agency (ARENA), announced in June 2026, is specifically to build a commercial-scale demonstration facility at the Port Kembla industrial precinct, in partnership with BlueScope Steel [Startup Daily, June 2026]. This facility is planned to produce up to 230 tonnes of SiCx per year for customer qualification and early sales [InvestMETS, June 2026].
Total disclosed funding now sits at roughly A$60.6 million, a war chest that underscores the capital intensity of advanced materials manufacturing [CB Insights, retrieved 2026]. The headcount has grown in step, from 38 employees in 2025 to 54 in 2026, as the company staffs up for its build-out [Revelio Labs, retrieved 2026].

The team built for scale
The founders bring a classic, complementary split: one for the market, one for the molecule. CEO Christiaan Jordaan is a mining and materials industry veteran, with former roles as Managing Director at New Energy Minerals and a manager at BHP [Reuters, June 2011]. His background is in scaling resource projects and navigating industrial partnerships. CTO and co-founder Andrew Minett is the materials scientist, with two decades of experience focused on devices and electrochemistry [Andrew Minett - Sicona Battery Technologies | LinkedIn, retrieved 2026]. It’s a pairing designed to bridge the gap between a promising lab result and a product sold by the tonne to multinational corporations.
The incumbent on the other side of the ledger
For all its promise, Sicona’s path is paved with formidable competitors, both old and new. The most direct is the entrenched graphite anode supply chain, a global industry that is cheap, reliable, and improving. Then there are the other silicon anode startups, many better-funded and further along in partnerships with automakers. Sicona’ most credible foil might be a company like Sila Nanotechnologies, which has raised over $900 million, signed a supply agreement with Mercedes-Benz, and is already ramping up production in the United States.
Sicona’s answer rests on two points: its silane-free process, which it argues is safer and more sustainable, and its strategic manufacturing partnership in India, which provides a capital-efficient path to a huge regional market. The next twelve months will be about proving its unit economics at the 230-tonne scale. If its Port Kembla demo plant can produce material that meets spec at a competitive cost, the conversation shifts from technical validation to commercial orders.
A back-of-envelope calculation illustrates the stakes. If Sicona’s material delivers the claimed 20% boost in energy density, that could translate to an extra 100 kilometers of range on a typical 500-km EV battery pack, or allow for a 20% smaller, lighter, and cheaper pack for the same range. For a grid storage project, that density gain means fewer cells, less space, and lower balance-of-system costs. The incumbent it must beat isn’t another startup; it’s the relentless cost-down curve of conventional graphite, improved year after year by incremental engineering. Sicona’s bet is that a better powder, made the right way, can outrun that curve.
