Can aluminium replace lithium in future batteries? A nascent battery architecture aims to lower costs while improving safety and supply resilience.
EQONIC Group has announced aluminium as the core chemistry behind its proprietary battery technology, marking a step towards commercialising a lithium-free, sodium-free and rare-earth-free energy storage system. The UK-based company is now progressing the technology towards industrial validation, where its manufacturability, performance and reliability will be assessed under commercial-scale conditions.
As demand for batteries continues to rise across electric mobility, renewable energy storage and industrial applications, manufacturers are exploring alternatives to conventional lithium-based chemistries. Critical materials such as lithium and rare earths are often subject to supply chain constraints and price fluctuations, driving research into battery technologies that rely on more abundant and widely available elements. Aluminium offers an established global supply chain and is one of the most abundant metals in the Earth’s crust, making it a potential candidate for next-generation energy storage systems.
According to the company, the aluminium-based chemistry is designed to reduce material costs to around 30% of those associated with conventional lithium-metal batteries while targeting a manufacturing cost of £50/kWh at scale. The battery architecture is inherently non-flammable, eliminating the thermal runaway risk associated with many lithium-based batteries. The technology also avoids the use of sodium and rare-earth materials, offering an alternative battery design based on readily available resources.
The next stage of development will focus on validating the battery technology under industrial-scale conditions to assess manufacturing processes, reliability and performance before commercial deployment. The company expects this phase to demonstrate whether the aluminium-based chemistry can be produced consistently at volumes required for practical energy storage applications.
Jas Kandola, Founder and Chief Executive Officer at EQONIC Group says, “Aluminium-based chemistry gives us everything we set out to achieve—material abundancy, high levels of safety and low cost—without the trade-offs that lithium, sodium and rare earth materials carry. Confirming the chemistry is one part of the story; progressing towards industrial validation is the part that matters most, and that’s exactly where our focus is now.”
