Naxion Energy, formerly known as Sodion Energy, has announced the launch of its Sodium-ion–based Energy Storage Systems, marking a significant advancement in India’s emerging energy storage landscape. The company, positioned as India’s first dedicated Sodium-ion energy enterprise, has designed, developed, and manufactured the new systems at its Coimbatore facility.
The all-in-one energy platform integrates an inbuilt battery, inverter, and solar MPPT, offering a safer, lighter, and more cost-effective alternative to traditional lead-acid batteries. Engineered to address the rising demand for reliable, maintenance-free storage solutions, the technology targets residential, commercial, industrial, and defence applications, and is built to perform efficiently across India’s extreme climatic conditions. The systems feature a zero-maintenance design, eliminating water top-ups, corrosion, swelling, and frequent servicing while ensuring long-term operational stability.
Speaking at the launch, G. Satheesh Reddy, Former Chairman of the Defence Research and Development Organisation (DRDO) and Scientific Adviser to the Defence Minister, lauded the milestone. He said Sodium-ion technology offers critical advantages by addressing material constraints faced by conventional battery chemistries. He added that Naxion Energy’s innovation would support India’s pathway toward greater energy security, self-reliance, and clean energy adoption.
Naxion Energy highlighted the inherent safety of Sodium-ion chemistry, which is non-flammable and non-toxic, reducing risks of thermal runaway—an essential requirement for installations in dense residential and commercial environments. The chemistry’s ability to support higher charge and discharge rates enables faster charging and high-power output, allowing the systems to handle high-inductive loads such as air-conditioners, pumps, compressors, and industrial machinery, capabilities that existing battery technologies often struggle to support.
Abishek Reddy, CEO of Naxion Energy India, said the company’s goal extends beyond introducing a new battery product. He emphasized that Sodium-ion technology offers India a unique opportunity to develop an indigenous supply chain, reducing dependence on imported materials. He also noted that the company aims to collaborate with OEMs and expand deployment across high-demand mobility and industrial sectors.
India remains among the world’s largest users of diesel generators, commonly relied upon for domestic, commercial, and industrial backup power. Naxion’s Sodium-ion platform is designed as a direct replacement for diesel generators, offering 2–3 times longer life than lead-acid systems, lower operational costs, and reduced downtime. With up to 60% lower weight and a compact, modular design, the systems provide installation flexibility across diverse environments. They are built to operate reliably between –30°C and +70°C, ensuring consistent performance during outages and peak-demand scenarios.
The storage systems will be available in 3.5 kW, 5 kW, and 10 kW versions, each with expandable battery capacity. The company plans to position Sodium-ion technology as the foundation for a fully localized and sustainable battery ecosystem.
Naxion Energy India is preparing for a significant expansion, planning an investment of ₹200 crore by the end of next year to upgrade manufacturing capabilities and grow its workforce by 50%. The company is also establishing a new manufacturing facility in Telangana, scheduled to become operational next year, to meet increasing demand from OEMs and enterprise customers.
The company currently serves several major clients, including Sagar Cements, the Tamil Nadu Forest Department, TAFE dealerships, MSME clusters, logistics operators, and specialty vehicle manufacturers, supported through a growing dealer network across major cities.
With fully indigenous Sodium-ion technology encompassing design, engineering, and manufacturing, Naxion Energy aims to accelerate India’s progress toward electrification, supply-chain independence, and sustainable industrial growth.
