Eos produces zinc-based battery energy storage systems. The company's technology overcomes the limitations of traditional lithium-ion batteries paovides discharge time from 3 to 12 hours. The Eos Z3 zinc-based wet battery module includes zinc cathode, aqueous electrolyte, bipolar electrodes and polymer housing. The electrodes offer high mechanical strength, corrosion resistance and chemical stability, ensuring years of operation with virtually no degradation. Furthermore, the bipolar structure simplifies the battery's internal connections, reducing internal resistance and increasing energy conversion efficiency. The company is also developing a software platform for managing the energy storage system, which implements real-time intelligence, advanced control capabilities and AI-based analytics.
