Zelestium Technologies S. L. is a Spanish deep-tech company founded in 2018 by CEO Joaquín Chacón and CRO Paloma Almodóvar. The firm develops and manufactures smart aluminum-ion (Al-ion) batteries, positioning itself as a sustainable and efficient alternative to conventional energy storage technologies. Its core mission is to address Europe’s strategic dependence on foreign suppliers for critical raw materials like lithium and cobalt. The company’s primary products are aluminum-ion cells and an associated IoT cloud platform.
These smart batteries are designed for stationary applications within smart grids, renewables, industrial energy storage, and backup systems. A key feature is their integration with an IoT platform that collects real-time performance data, enabling remote monitoring and AI-driven analytics to optimize battery lifespan. This facilitates B2B models such as Battery-as-a-Service and supports a circular economy by enabling a second life for the batteries. Zelestium’s technology is notable for its safety, as Al-ion batteries do not present the fire or explosion risks associated with lithium-ion batteries.
They are also highly recyclable, use no critical or toxic materials, and boast a long lifespan of up to 6,000 cycles. The company is also engaged in research and development of aluminum-air (Al-air) battery systems, which could offer very high energy density for applications like electric vehicles and long-endurance drones. Zelestium was selected to participate in the NATO DIANA 2024 cohort, highlighting the strategic importance of its technology for energy resilience.
