Indi Energy, established in 2019, is an Indian energy storage startup dedicated to developing and manufacturing sodium-ion batteries. Founded by four scientists and engineers from IIT Roorkee, the company creates sustainable energy solutions that support global environmental standards and United Nations Sustainable Development Goals. Their primary focus lies in producing efficient, cost-effective alternatives to traditional lithium-ion and lead-acid batteries, while maintaining a completely indigenous supply chain as part of India’s self-reliance initiative.
Battery Technology
Indi Energy’s sodium-ion batteries represent a significant advancement in energy storage technology. These batteries achieve 90-95% energy efficiency and maintain performance for over 2,000 cycles, making them particularly suitable for various applications. The company’s proprietary Hard Carbon (BioBlack™) technology, derived from agricultural and biowaste, serves as an innovative anode material that enhances battery performance while promoting sustainability.
The company has developed specialized sodium-ion cathode materials and electrolytes that contribute to improved battery efficiency and longevity. Their battery packs are customized to meet specific environmental requirements and quality standards, offering solutions for multiple sectors including renewable energy storage, electric vehicles, and consumer electronics.
One distinctive aspect of Indi Energy’s technology is its cost-effectiveness, achieved through the use of readily available sodium instead of rare earth materials. This approach not only reduces production costs but also ensures a more sustainable manufacturing process. The company’s batteries are designed to function effectively in various temperature conditions, making them suitable for India’s diverse climate zones.
Recent Projects
In 2024, Indi Energy received recognition through the SIDBI Environmental Challenge, acknowledging their contributions to sustainable energy solutions. The company has expanded its research and development activities, focusing on enhancing their sodium-ion battery technology for electric vehicle applications. Their ongoing project includes scaling up production capabilities to meet growing market demands and establishing partnerships with various industry stakeholders.
Investors
Indi Energy secured $1.5 million in pre-Series A funding led by Big Capital in September 2022. Additional investment support came from Mumbai Angels Network and several high-net-worth individuals. This funding has been instrumental in advancing their research and development initiatives while expanding their manufacturing capabilities.
