EExion Energy specializes in advanced carbon battery technology, developing innovative solutions that transform activated carbon into efficient cathodes through organic chemistry modifications. The company’s patented approach increases energy density while minimizing environmental impact traditionally associated with lithium-ion batteries. Founded in Israel, EExion creates sustainable energy storage alternatives that address critical challenges in renewable energy adoption, including supply chain dependencies, environmental concerns, and performance limitations. Their technology efficiently operates across various ion types and electrolyte systems, offering significant advantages in both grid storage and electric vehicle applications.

Battery Technology

EExion’s proprietary technology centers on modified carbon electrodes that function with multiple ion types (H+, Li+, Na+, Zn++) in both aqueous and organic electrolytes. This versatility enables nearly double the energy density compared to conventional systems. The innovation eliminates dependence on scarce materials while improving recyclability and long-term performance.

The company’s “Energize-N’-Go” product line features supercapacitors designed for rapid charging applications. These devices maintain capacity through thousands of charge cycles, significantly outperforming traditional batteries. The technology shows particular promise in micro-mobility applications, including e-scooters, electric bikes, and motorcycles. For grid storage applications, EExion’s solutions offer enhanced energy density and extended operational life, reducing installation space requirements and long-term maintenance costs.

Recent Projects

In recent developments, EExion has focused on implementing its five-minute charging technology for electric vehicles. Their carbon electrode technology has demonstrated charging speeds up to 100 times faster than traditional lithium-ion batteries. The company’s systems have achieved over 30,000 recharging cycles in testing, maintaining consistent performance throughout their operational life. EExion has also expanded its application scope to include warehouse robotics and shared electric vehicle systems.

Investors

EExion has secured significant financial support through a seed funding round led by Capital Nature, with participation from 4WARD VC and Climate Capital Collective (C3). The company receives additional support from ESIL (Energy Storage Innovation Lab), backed by EDF Renewables Israel, Johnson Matthey, and BAZAN Group. Several European angel investors have also contributed to the company’s funding, supporting the development and commercialization of its energy storage technology.
