Our technology

IonycLeaf Silix™

At IonycLeaf, we are at the forefront of innovation with the development of Silicon-Sulphur batteries, a patented technology that redefines energy storage standards. Our mission is to create energy solutions that combine efficiency and sustainability, and advanced silicon and sulfur chemistry is a perfect example of this.

Silicon-Sulfur batteries represent a significant advancement, offering much greater capacity compared to traditional lithium-ion batteries. We use silicon in the anode, known for its high capacity to store lithium ions, and sulfur in the cathode, which can store a large amount of energy. This combination results in batteries that not only store more energy, but also charge faster and are safer.
