e-TRNL Energy is an innovative battery technology startup based in Mumbai, India, established in 2021 by technologists Apoorv Shaligram and Uttam Sen. The company specializes in developing advanced lithium-ion battery cells, focusing on solving critical challenges in the electric vehicle industry. With their combined experience of over 25 years in battery technology and energy storage, the founders bring substantial expertise from prestigious institutions like IIT Roorkee and IIT Bombay.
The company’s primary mission is to eliminate range anxiety in electric vehicles by creating battery solutions that enable faster charging without compromising safety or longevity. Their approach involves a complete redesign of battery cell architecture to optimize current flow and reduce internal resistance, addressing fundamental issues in contemporary battery technology.
Battery Technology
At the core of e-TRNL Energy’s innovations is their proprietary 3D Electrode Architecture (3DEA) technology. This patented system represents a significant advancement in cell manufacturing, eliminating the need for conventional coated electrodes while simplifying the production process. The technology reduces internal resistance through modified cell core design, enabling faster charging capabilities without compromising battery life.
The company has developed a new prismatic cell format that fundamentally changes how current flows inside the battery. By allowing current to pass through the shortest dimension of the cell in a straight line, this design minimizes energy consumption and heat generation. The technology is chemistry-agnostic, making it adaptable across various battery compositions and applications.
Their manufacturing process aims to reduce production steps by approximately 50% compared to traditional methods, potentially decreasing capital expenditure by up to 80%. The company projects achieving a cost target of $100/kWh by 2025, a critical milestone for widespread electric vehicle adoption.
Recent Projects
In recent developments, e-TRNL Energy has focused on advancing their technology readiness level (TRL). The company aims to reach TRL 5 or 6 by early 2025, marking significant progress toward commercialization. They have successfully completed internal trials and proof of concept demonstrations, validating their innovative approach to battery cell design and manufacturing.
Investors
e-TRNL Energy has secured approximately $910,000 (INR 7.5 crores) in pre-seed funding. The investment round was led by Speciale Invest, a deep-tech venture capital firm, with participation from Micelio Mobility and the Centre for Innovation Incubation and Entrepreneurship (CIIE). This funding supports their research and development efforts and accelerates their product development timeline.
