Company Overview

Aatral ESP is an innovation-driven company headquartered in Chennai, India, pioneering sustainable energy storage through cutting-edge sodium-ion battery technology. Founded to address the limitations of traditional lithium-ion systems, the company specializes in developing affordable, safe, and eco-friendly battery solutions designed to accelerate the shift toward clean energy while supporting domestic manufacturing. Led by CEO Ms. Subathra Rajendran, an ex-ISRO scientist with over two decades of energy sector expertise, Aatral ESP is committed to decarbonizing the world through next-generation storage systems. The company’s mission emphasizes creating scalable and environmentally conscious technologies that reduce dependency on lithium imports and bolster energy resilience in emerging economies. Beyond technical advancement, Aatral ESP champions gender diversity in STEM fields, empowering women through training programs and leadership opportunities.

Battery Technology

Aatral ESP’s core technology centers on sodium-ion batteries utilizing patented NASICON (sodium super-ionic conductor) chemistry. This innovation enhances power density and durability while ensuring fire safety and thermal stability across extreme temperature ranges (-40°C to 60°C). The NASICON-based design allows ions to move freely between electrodes without thermal runaway risks, eliminating overheating and short-circuit hazards common in lithium systems. With a lifespan exceeding 10,000 charge-discharge cycles, the cells deliver consistent performance for decades. Cost efficiency is a hallmark: batteries are priced between $40–$80 per kWh. Production processes reduce carbon emissions by up to 90% per kWh, leveraging abundant sodium resources and low-cost raw materials. Applications span grid storage, solar energy systems, and mobile infrastructure, including telecom backup systems and EV-ready storage. Complementary products like flower wind turbines and hydrogen-fuel-cell hybrids further diversify Aatral ESP’s portfolio, offering versatile solutions for off-grid, industrial, and renewable energy integration.
