As battery storage becomes increasingly important to a net zero energy system, the materials used to make batteries are coming under closer scrutiny. EQONIC, one of our battery supply partners, is developing a different approach: an aluminium-based battery technology that does not rely on lithium, sodium or rare earth materials. The company says this choice of chemistry is intended to improve affordability, safety and supply-chain resilience while offering a more sustainable route for large-scale energy storage. Here is more detail from EQONIC:
EQONIC has confirmed that aluminium is the core material in its proprietary composite. This is significant because aluminium is abundant, widely available and supported by established supply chains. By contrast, many conventional battery technologies depend on critical minerals that can be exposed to price volatility, geopolitical risk, export restrictions and environmental concerns linked to extraction and processing.
The company’s aim is to create a battery platform that can be manufactured at a much lower cost than traditional lithium-ion systems. EQONIC is targeting a manufactured cost of £50 per kWh at scale, which it says would be roughly half the current industry average. If proven through testing and manufacturing scale-up, that level of cost reduction could help make battery energy storage systems more accessible and support wider deployment of renewable electricity.
Safety is also central to the technology’s positioning. EQONIC’s aluminium-based chemistry is inherently non-flammable, reducing the risk of thermal runaway that has been associated with fires in some conventional battery systems. That characteristic could be particularly relevant for stationary storage projects, electric vehicles and other applications where reliability, public confidence and safe operation are essential.
EQONIC is now moving the technology from laboratory development towards industrial validation. This stage is designed to test whether the battery can be manufactured consistently and perform reliably at the volumes required for commercial deployment. In other words, the next milestone is not simply proving the chemistry works, but demonstrating that it can be produced, tested and scaled in real-world conditions.
Founder and CEO Jas Kandola has said the aluminium approach delivers the combination the company was looking for: abundant materials, high levels of safety and low cost, without the compromises associated with lithium, sodium or rare earths. EQONIC’s decision to avoid sodium as well as lithium is notable, because sodium-ion batteries are gaining attention but still face challenges around scaling and supply-chain efficiency.
For organisations looking to decarbonise energy use, the potential appeal is clear. A lower-cost battery made from abundant materials could reduce dependence on constrained mineral markets and make storage projects easier to justify economically. It could also help reduce the environmental impact associated with sourcing scarce battery materials, while improving resilience by relying on supply chains that are already more mature and geographically diverse.
However, the technology still needs to pass the industrial validation stage before its commercial potential can be fully assessed. Performance, durability, manufacturability and cost all need to be proven at scale. If EQONIC can demonstrate those qualities, its aluminium-based battery could become an important alternative in the storage market, particularly for applications where safety, sustainability and affordability are priorities.
