Battery cell technology startup e-TRNL Energy has secured ₹27.4 crore (approximately $3 million) in a seed funding round led by IAN Group through its IAN Alpha Fund. The round also saw participation from Navam Capital, Speciale Invest, and other investors.
The newly raised capital will be deployed to complete product development, validate performance and safety benchmarks, and demonstrate scalable manufacturing capability within India.
Founded in 2021 by Apoorv Shaligram and Dr Uttam Kumar Sen, e-TRNL Energy is focused on building next-generation battery cell technology by re-engineering core cell architecture and optimizing manufacturing processes. The company aims to strengthen India’s domestic battery innovation ecosystem at a time when energy storage and EV adoption are accelerating.
The startup has already set up a 20,000 sq. ft. R&D and early-stage manufacturing facility in Bengaluru, laying the groundwork for indigenous battery cell development. It has secured two granted patents and filed additional patent applications, reflecting its emphasis on intellectual property-led innovation.
Looking ahead, e-TRNL plans to establish a 250 MWh pilot manufacturing facility by 2027, with ambitions to scale production capacity to 2 GWh in the subsequent phase.
Its first commercial product will be based on LFP (Lithium Iron Phosphate) chemistry, a battery format widely known for its safety and durability advantages. The company also has future plans to develop LMFP (Lithium Manganese Iron Phosphate) and sodium-ion battery technologies as part of its broader roadmap.
With fresh funding and an expanding IP portfolio, e-TRNL Energy is positioning itself as a homegrown player in India’s rapidly evolving battery cell and energy storage landscape.
