Battery cells with 3D Electrode Architecture for electric vehicles & energy storage, enabling fast charging, high energy density, and safety.
Established in 2021 by Indian Institute of Technology Bombay alumni Apoorv Shaligram and Uttam Sen, e-TRNL Energy is a B2B company based in Mumbai, Maharashtra, India, developing chemistry-agnostic 3D Electrode Architecture for the electric vehicle and energy storage sectors. The firm's proprietary structural design minimizes internal resistance and thermal waste across various battery chemistries, including standard Li-ion and Na-ion formats, enabling safe fifteen-minute charging cycles and higher energy density. By implementing a highly efficient and modular production process, the enterprise has successfully streamlined traditional battery manufacturing requirements from twenty-four distinct steps down to just eight. Operating with fewer than ten employees, the business has raised approximately $3.3 million, or 27.4 crore rupees, in seed funding backed by lead investor Speciale Invest. This capital supports the commercialization of their advanced cell technology for markets requiring safe, fast-charging solutions.

e-TRNL Energy is a Mumbai-based technology company specializing in advanced battery cell technology for the energy storage sector, particularly targeting electric vehicles (EVs). The company develops chemistry-agnostic battery cells that enable ultrafast charging—around 15 minutes—while significantly reducing heating and enhancing battery longevity. Their innovation addresses critical EV challenges such as charging speed, battery degradation, and thermal management, serving EV manufacturers and the broader clean mobility ecosystem. Founded in 2021, e-TRNL Energy is gaining momentum by promising superior manufacturing economics and scalable production of high-performance battery packs[1][2][4].
e-TRNL Energy was founded in 2021 by Apoorv Shaligram and Uttam Sen, both alumni of prestigious Indian Institutes of Technology (IIT Bombay and IIT Roorkee). The founders identified fundamental issues in existing EV battery cells—excessive heating, slow charging, and limited lifespan—and set out to develop a novel cell design that overcomes these barriers. Early traction came from their chemistry-agnostic technology that supports current lithium-ion and future sodium-ion chemistries, positioning them as innovators in the evolving battery landscape[1][2][3].
e-TRNL Energy rides the global trend toward electrification of transport and the urgent need for sustainable energy storage solutions. The timing is critical as EV adoption accelerates worldwide, demanding batteries that charge faster, last longer, and cost less. Market forces such as climate change policies, rising fuel costs, and technological advances in battery chemistry favor companies like e-TRNL Energy. By addressing key pain points in EV battery technology, they contribute to lowering barriers for EV adoption and influence the broader clean energy ecosystem through innovation in cell design and manufacturing scalability[1][4].
Looking ahead, e-TRNL Energy is poised to scale production and expand its impact in the EV battery market, potentially influencing global supply chains with its cost-effective, high-performance cells. Trends such as the shift to sodium-ion batteries and increasing demand for ultrafast charging will shape their trajectory. Their ability to maintain superior economics while delivering advanced technology could position them as a key player in the next generation of energy storage solutions, reinforcing their role in accelerating the transition to sustainable mobility[1][4].
