One of antimony's most established applications is in lead-acid batteries.
While these batteries are often associated with vehicles, they are also widely used in backup power systems, industrial installations, telecommunications infrastructure and renewable energy projects around the world. Their robustness, reliability and proven track record continue to make them an important part of the global energy landscape.
In these batteries, small amounts of antimony are added to improve the strength and durability of key components. This helps batteries perform reliably over many years, even in demanding operating conditions. Although only a small proportion of the battery, antimony contributes significantly to the overall performance and lifespan of the system.
As more renewable energy comes online, the role of energy storage continues to grow. Solar panels generate electricity during the day, while wind production varies according to weather conditions. Effective storage solutions help bridge these fluctuations and contribute to a more resilient and flexible energy system. Proven battery technologies remain an important part of that transition, particularly in applications where reliability and safety are critical.
Antimony also has a strong circularity story. Lead-acid batteries are among the most successfully recycled consumer and industrial products in the world. In Europe and many other regions, well-established collection and recycling systems recover battery materials and return them to productive use. This helps reduce waste, conserve resources and support a more sustainable value chain.
Looking ahead, researchers continue to explore the potential of antimony in new energy-storage technologies. While these developments are still emerging, they demonstrate how a material with a long industrial history can also contribute to future innovation.
From backup power and industrial applications to the broader energy transition, antimony continues to support technologies that store electricity, strengthen infrastructure and help keep modern society running.
