Naxion Energy Claims To Launch India’s First Sodium-Ion ESS

Naxion Energy has launched what it says is India’s first sodium-ion energy storage systems, aiming to offer a fully local and safer alternative to lead-acid batteries for residential, commercial and industrial use.

The systems, designed and manufactured at the company’s Coimbatore facility, integrate a battery, inverter and solar MPPT in a single unit. Naxion, formerly Sodion Energy, said the technology is intended to serve as a lighter, maintenance-free and more cost-efficient replacement for conventional backup solutions, with long cycle life and performance suited to extreme Indian climates.

Reducing Material Dependence 

Speaking at the launch, G. Satheesh Reddy, former chairman of the Defence Research and Development Organisation (DRDO), said sodium-ion technology could help India reduce material dependence and enhance long-term energy security. “This milestone marks an important step forward in strengthening India’s path toward energy security and self-reliance,” he said.

Naxion said sodium-ion chemistry is non-flammable and non-toxic, reducing fire-risk concerns associated with lithium-ion systems and enabling deployment in dense urban and indoor environments. The company said its batteries support high charging and discharging rates, allowing faster charging and the ability to run high-inductive loads such as air conditioners, pumps and industrial machinery that conventional technologies cannot reliably support.

Domestic Supply Chain

Chief Executive Abishek Reddy said the company aims to build an indigenous supply chain around sodium-ion technology. “Our goal is much larger than introducing a new battery. We are building the backbone for India’s future energy systems,” he said. The firm plans to work with OEMs and equipment manufacturers to integrate the chemistry into mobility and stationary applications.

India remains one of the world’s largest users of diesel generators, and Naxion said its systems can directly replace gensets while offering two to three times longer life than lead-acid batteries. The platform, available in 3.5 kW, 5 kW and 10 kW models with expandable capacity, is designed to operate from –30°C to 70°C and weighs up to 60% less than comparable lead-acid systems.

Plans For Rs 200cr

The company plans to invest ₹200 crore by the end of 2026 to scale manufacturing and increase its workforce by 50%. A new plant in Telangana, due to be operational next year, will support growing demand from OEMs and enterprise customers.

Naxion said it is expanding its dealer network across major Indian cities and counts Sagar Cements, the Tamil Nadu Forest Department, TAFE dealerships, MSME clusters, logistics firms and specialty vehicle manufacturers among its customers.

Founded in 2024 and backed by ₹25 crore in funding, Naxion Energy develops sodium-ion battery packs for mobility, industrial equipment, marine applications and grid-scale storage. The company says sodium-ion technology, with zero fire risk and high-rate charging capability, positions it to become a global participant in sustainable energy storage.
