Naxion Energy claims launch of India’s first sodium-ion energy storage systems

Naxion Energy (formerly Sodion Energy) has introduced its sodium-ion–based energy storage systems for the residential and commercial & industrial (C&I) sectors. The storage systems are available in 3.5 kW, 5 kW, and 10 kW models, and the batteries can be expanded to double the system’s storage capacity.

“The Coimbatore plant has annual sodium-ion battery pack production capacity of 1.5 GWh. We will invest INR 200 crore in setting up a pilot sodium-ion cell manufacturing plant with a capacity of 500 MWh by 2027. Additionally, we will set up a battery pack assembly plant with a capacity of 1 GWh in Hyderabad,” Abishek Reddy, CEO of Naxion Energy India, told pv magazine.

Designed, developed, and manufactured at its Coimbatore plant, the new all-in-one energy storage platform comes with a fully integrated battery, inverter, and solar MPPT.

The company said its sodium-ion–based energy storage systems offer a more cost-efficient alternative to legacy lead-acid batteries. The technology is engineered to meet the growing demand for clean, reliable, and maintenance-free energy storage across the residential, commercial, industrial, and defence sectors, delivering long cycle life and exceptional performance in extreme Indian climates. With a zero-maintenance design – requiring no water top-ups and exhibiting no corrosion, swelling, or need for periodic service – the systems ensure predictable, long-term reliability.

“As India’s energy generation and mobility landscape continues to evolve, the need for efficient, sustainable, and secure energy storage solutions has never been greater. Sodium-ion technology holds immense potential, especially in addressing the critical material constraints associated with conventional battery systems. This milestone marks an important step forward in strengthening India’s path toward energy security and long-term self-reliance,” said G. Satheesh Reddy, former chairman, Defence Research and Development Organisation (DRDO), and scientific advisor to the Defence Minister.

The inherently safe, non-flammable, and non-toxic sodium-ion chemistry eliminates the risks associated with thermal runaway, making it ideal for dense residential areas, commercial buildings, and enclosed indoor installations. Sodium-ion’s unique chemistry also enables much higher charge and discharge rates than lead-acid or lithium chemistries. This translates into significantly faster charging speeds and higher power output, allowing Naxion’s new energy systems to run high-inductive loads such as air conditioners, compressors, pumps, and industrial applications including welding, cutting, and grinding—capabilities that traditional battery technologies cannot reliably support.

Abishek Reddy, CEO of Naxion Energy India, said, “Our goal is much larger than introducing a new battery. We are building the backbone for India’s future energy systems—safe solutions, fully local, and accessible to every market segment. Sodium-ion gives India the rare opportunity to establish an indigenous supply chain without dependency on scarce imports. With this platform, our strategy is to scale across high-demand sectors, collaborate with OEMs, and enable mobility and equipment manufacturers to transition to cleaner and more reliable power sources.”

India continues to be one of the world’s biggest users of diesel generators for commercial, industrial, and home backup applications, and these systems come with significant drawbacks, including pollution, high operating costs due to rising fuel prices, noise, and extensive maintenance requirements.

Naxion’s sodium-ion energy storage platform is designed to directly replace diesel generators and address the long-standing limitations of traditional lead-acid–based backup systems by offering up to three times longer life while significantly reducing operational costs and downtime. With up to 60% lower weight and a compact, modular footprint, the systems offer flexible installation options for homes, enterprises, and industrial spaces. Engineered to perform reliably across extreme temperatures from –30°C to +70°C, they deliver consistent backup power even in India’s harshest climates, ensuring stability during outages and peak load conditions.

“As we expand, our focus is on manufacturing efficiency, product diversification, and forming partnerships that help deploy sodium-ion technology at a national scale. Every advancement we make takes us one step closer to energy independence, and we’re committed to leading that shift,” Reddy added.

By the end of next year, Naxion Energy India plans to invest INR 200 crore to enhance its manufacturing capabilities and expand its workforce by 50%. As part of its India-wide expansion, the company is also setting up a new manufacturing plant in Telangana to support growing demand from both OEMs and enterprise customers. The new facility is expected to become operational next year.

Naxion currently works with an expanding network of dealers across major cities, serving customers such as Sagar Cements, the Tamil Nadu Forest Department, TAFE dealerships, MSME industrial clusters, regional logistics operators, and specialty vehicle manufacturers, among others.

Founded in 2024, Naxion Energy develops high-performance sodium-ion battery packs for mobility and energy storage applications. In the storage segment, it offers residential, commercial, industrial, and grid-scale BESS solutions. In the mobility segment, it produces packs for heavy machinery, mobility, marine, and defence sectors.
