Battery innovation startup e-TRNL Energy has secured ₹27.4 crore (approximately $3 million) in a seed funding round to accelerate the development of advanced energy storage solutions and strengthen its domestic manufacturing capabilities.
The fresh capital will support the company’s efforts to refine its proprietary battery cell architecture, complete rigorous safety and performance testing, and establish scalable production processes within India.
Investor Participation and Capital Deployment
The funding round was led by IAN Group through its IAN Alpha Fund, with participation from Navam Capital, Speciale Invest, and other backers.
The proceeds will primarily be directed toward:
- Finalising engineering design and product optimisation
- Conducting advanced safety and lifecycle validations
- Building manufacturing processes ready for commercial scaling
- Strengthening India-based battery cell production infrastructure
The company’s focus remains on reducing dependency on imported cell technologies by developing indigenous alternatives tailored to Indian operating conditions.
Company Background and Innovation Approach
Founded in 2021 by Apoorv Shaligram and Dr. Uttam Kumar Sen, e-TRNL Energy is working to redesign battery cell structures and production methodologies rather than adopting standard global formats.
The startup operates from a 20,000 sq. ft. research and early-stage manufacturing facility in Bengaluru. It has already secured two patents and has additional applications under review, reflecting its emphasis on deep-tech innovation in cell design and process engineering.
Manufacturing Roadmap and Technology Plans
As part of its growth strategy, e-TRNL Energy aims to establish:
- A 250 MWh pilot production facility by 2027
- A future scale-up to approximately 2 GWh manufacturing capacity in subsequent phases
The pilot facility will serve as a validation platform to test manufacturing stability, process efficiency, and commercial viability before large-scale expansion.
Chemistry and Product Strategy
The company’s initial commercial offerings will be based on LFP (Lithium Iron Phosphate) chemistry, known for safety, durability, and cost efficiency. Over time, it plans to expand into:
- LMFP (Lithium Manganese Iron Phosphate)
- Sodium-ion battery technologies
Through innovations in cell architecture and production methods, e-TRNL aims to deliver safer, more cost-effective, and scalable battery solutions for India’s growing energy storage and electric mobility ecosystem.
Summary
e-TRNL Energy has raised ₹27.4 crore in seed funding led by IAN Alpha Fund, with participation from Navam Capital and Speciale Invest. The capital will be used to advance next-generation battery cell engineering and strengthen domestic manufacturing capabilities. The startup operates a 20,000 sq. ft. facility in Bengaluru, holds multiple patents, and plans to build a 250 MWh pilot plant by 2027, with a long-term goal of reaching 2 GWh capacity. Its initial focus will be on LFP-based cells, followed by LMFP and sodium-ion technologies, positioning the company as an emerging player in India’s energy storage landscape.
